Pernicious Anemia and Other B Vitamin Deficiencies

Pernicious Anemia Test and health information

Pernicious anemia is a type of anemia in which the intestines cannot effectively absorb vitamin B12, which results in a reduced count of red blood cells that are important for getting oxygen to the body's cells. 

You can get pernicious anemia when you don't get enough vitamin B12. People with a deficiency of vitamin B12 can't properly absorb this nutrient from their food. They can't make enough healthy red blood cells to meet their body's needs. 

Our red blood cells need vitamin B12 for normal cell growth. It makes red blood cells too big when there is not enough of a certain nutrient. Cells that are too big may not be able to leave the bone marrow where they were made. A low number of red blood cells means that there are fewer cells that can carry oxygen to the body's most important parts, like the brain and heart, as well as other parts and cells. 

People with pernicious anemia may be tired, have headaches and dizziness, chest pain, pale skin, cold hands, and cold feet. Additionally, vitamin B12 deficiency can also cause numbness in the hands and feet, muscle weakness, loss of reflexes, issues with balance, nausea, bloating, heartburn, and confusion.

Pernicious anemia blood tests can provide an accurate reading of your reticulocyte counts, serum folate, iron, and iron-binding. These tests can help show whether you have pernicious anemia or another type of anemia, with confidential results available in 1 to 2 days online when ordered from Ulta Lab Tests after specimen collection.

Listed below are lab tests to detect, diagnose and monitor pernicious anemia.

Description: A CBC or Complete Blood Count with Differential and Platelets test is a blood test that measures many important features of your blood’s red and white blood cells and platelets. A Complete Blood Count can be used to evaluate your overall health and detect a wide variety of conditions such as infection, anemia, and leukemia. It also looks at other important aspects of your blood health such as hemoglobin, which carries oxygen. 

Also Known As: CBC test, Complete Blood Count Test, Total Blood Count Test, CBC with Differential and Platelets test, Hemogram test  

Collection Method: Blood Draw 

Specimen Type: Whole Blood 

Test Preparation: No preparation required 

When is a Complete Blood Count test ordered?  

The complete blood count (CBC) is an extremely common test. When people go to the doctor for a standard checkup or blood work, they often get a CBC. Suppose a person is healthy and their results are within normal ranges. In that case, they may not need another CBC unless their health condition changes, or their healthcare professional believes it is necessary. 

When a person exhibits a variety of signs and symptoms that could be connected to blood cell abnormalities, a CBC may be done. A health practitioner may request a CBC to help diagnose and determine the severity of lethargy or weakness, as well as infection, inflammation, bruises, or bleeding. 

When a person is diagnosed with a disease that affects blood cells, a CBC is frequently done regularly to keep track of their progress. Similarly, if someone is being treated for a blood condition, a CBC may be performed on a regular basis to see if the treatment is working. 

Chemotherapy, for example, can influence the generation of cells in the bone marrow. Some drugs can lower WBC counts in the long run. To monitor various medication regimens, a CBC may be required on a regular basis. 

What does a Complete Blood Count test check for? 

The complete blood count (CBC) is a blood test that determines the number of cells in circulation. White blood cells (WBCs), red blood cells (RBCs), and platelets (PLTs) are three types of cells suspended in a fluid called plasma. They are largely created and matured in the bone marrow and are released into the bloodstream when needed under normal circumstances. 

A CBC is mainly performed with an automated machine that measures a variety of factors, including the number of cells present in a person's blood sample. The findings of a CBC can reveal not only the quantity of different cell types but also the physical properties of some of the cells. 

Significant differences in one or more blood cell populations may suggest the presence of one or more diseases. Other tests are frequently performed to assist in determining the reason for aberrant results. This frequently necessitates visual confirmation via a microscope examination of a blood smear. A skilled laboratory technician can assess the appearance and physical features of blood cells, such as size, shape, and color, and note any anomalies. Any extra information is taken note of and communicated to the healthcare provider. This information provides the health care provider with further information about the cause of abnormal CBC results. 

The CBC focuses on three different types of cells: 

WBCs (White Blood Cells) 

The body uses five different types of WBCs, also known as leukocytes, to keep itself healthy and battle infections and other types of harm. The five different leukocytes are eosinophiles, lymphocytes, neutrophiles, basophils, and monocytes. They are found in relatively steady numbers in the blood. Depending on what is going on in the body, these values may momentarily rise or fall. An infection, for example, can cause the body to manufacture more neutrophils in order to combat bacterial infection. The amount of eosinophils in the body may increase as a result of allergies. A viral infection may cause an increase in lymphocyte production. Abnormal (immature or mature) white cells multiply fast in certain illness situations, such as leukemia, raising the WBC count. 

RBCs (Red Blood Cells) 

The bone marrow produces red blood cells, also known as erythrocytes, which are transferred into the bloodstream after maturing. Hemoglobin, a protein that distributes oxygen throughout the body, is found in these cells. Because RBCs have a 120-day lifespan, the bone marrow must constantly manufacture new RBCs to replace those that have aged and disintegrated or have been lost due to hemorrhage. A variety of diseases, including those that cause severe bleeding, can alter the creation of new RBCs and their longevity. 

The CBC measures the number of RBCs and hemoglobin in the blood, as well as the proportion of RBCs in the blood (hematocrit), and if the RBC population appears to be normal. RBCs are generally homogeneous in size and shape, with only minor differences; however, considerable variances can arise in illnesses including vitamin B12 and folate inadequacy, iron deficiency, and a range of other ailments. Anemia occurs when the concentration of red blood cells and/or the amount of hemoglobin in the blood falls below normal, resulting in symptoms such as weariness and weakness. In a far smaller percentage of cases, there may be an excess of RBCs in the blood (erythrocytosis or polycythemia). This might obstruct the flow of blood through the tiny veins and arteries in extreme circumstances. 

Platelets 

Platelets, also known as thrombocytes, are small cell fragments that aid in the regular clotting of blood. A person with insufficient platelets is more likely to experience excessive bleeding and bruises. Excess platelets can induce excessive clotting or excessive bleeding if the platelets are not operating properly. The platelet count and size are determined by the CBC.

Commonly Asked Questions: 

How does my health care provider use a Complete Blood Count test? 

The complete blood count (CBC) is a common, comprehensive screening test used to measure a person's overall health status.  

What do my Complete Blood Count results mean? 

A low Red Blood Cell Count, also known as anemia, could be due many different causes such as chronic bleeding, a bone marrow disorder, and nutritional deficiency just to name a few. A high Red Blood Cell Count, also known as polycythemia, could be due to several conditions including lung disease, dehydration, and smoking. Both Hemoglobin and Hematocrit tend to reflect Red Blood Cell Count results, so if your Red Blood Cell Count is low, your Hematocrit and Hemoglobin will likely also be low. Results should be discussed with your health care provider who can provide interpretation of your results and determine the appropriate next steps or lab tests to further investigate your health. 

What do my Differential results mean? 

A low White Blood Cell count or low WBC count, also known as leukopenia, could be due to a number of different disorders including autoimmune issues, severe infection, and lymphoma. A high White Blood Cell count, or high WBC count, also known as leukocytosis, can also be due to many different disorders including infection, leukemia, and inflammation. Abnormal levels in your White Blood Cell Count will be reflected in one or more of your different white blood cells. Knowing which white blood cell types are affected will help your healthcare provider narrow down the issue. Results should be discussed with your health care provider who can provide interpretation of your results and determine the appropriate next steps or lab tests to further investigate your health. 

What do my Platelet results mean? 

A low Platelet Count, also known as thrombocytopenia, could be due to a number of different disorders including autoimmune issues, viral infection, and leukemia. A high Platelet Count, also known as Thrombocytosis, can also be due to many different disorders including cancer, iron deficiency, and rheumatoid arthritis. Results should be discussed with your health care provider who can provide interpretation of your results and determine the appropriate next steps or lab tests to further investigate your health. 

NOTE: Only measurable biomarkers will be reported. Certain biomarkers do not appear in healthy individuals. 

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Description: A B12 and Folate test measures the levels of B12 and folic acid in the blood. These results can be used to determine a B12 and/or folate deficiency and evaluate a person's nutritional status. Anemia and Neuropathy can also be evaluated using the results from this test.

Also Known As: Vitamin B12 and Folate test, Cobalamin and Folic Acid Test, Vitamin B12 and Vitamin B9 Test, Vitamin B12 Test, Vitamin B9 Test, Cobalamin Test, Folic Acid Test, Folate Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is Vitamin B12 and Folate panel test ordered?

When a complete blood count and/or blood smear, performed as part of a health checkup or anemia evaluation, reveal a low red blood cell count with the presence of big RBCs, B12 and folate levels may be ordered. A high mean corpuscular volume, in particular, implies that the RBCs are enlarged.

When a person exhibits the following signs and symptoms of a deficit, testing for B12 and folate levels may be necessary.

  • Diarrhea
  • Dizziness
  • Muscle weakness, fatigue
  • Appetite loss.
  • Skin that is pale
  • Irregular heartbeats, rapid heart rate
  • Breathing problems
  • Tongue and mouth ache
  • In the feet, hands, arms, and legs, there is tingling, numbness, and/or burning 
  • Confusion or obliviousness
  • Paranoia

When a person is at risk of deficiency, such as those with a history of malnutrition or a condition associated to malabsorption, B12 and folate testing may be ordered.

Individuals being treated for malnutrition or a B12 or folate deficit may have these tests done on a frequent basis to see how effective their treatments are. This could be part of a long-term therapy plan for people who have a disease that causes chronic deficiency.

What does a Vitamin B12 and Folate panel blood test check for?

The B complex of vitamins includes vitamins including vitamin B12 and folate. They are required for the creation of normal red blood cells, tissue and cell repair, and the synthesis of DNA, the genetic material in cells. Both are nutrients that the body cannot make and must be obtained from the diet.

Vitamin B12 and folate tests diagnose vitamin deficiencies by measuring vitamin levels in the liquid section of the blood. The amount of folate in red blood cells is sometimes tested as well.

Folate is a naturally occurring form of the vitamin, whereas folic acid is a supplement that can be added to foods and beverages. Leafy green vegetables, dry beans and peas, citrus fruits, yeast, and liver all contain it. Vitamin B12, also known as cobalamin, can be found in animal-based foods such red meat, fish, poultry, milk, yogurt, and eggs. Fortified cereals, breads, and other grain products have become key sources of B12 and folate in recent years.

A lack of B12 or folate can cause macrocytic anemia, a condition in which red blood cells are bigger than normal. Megaloblastic anemia is a kind of macrocytic anemia marked by the generation of fewer but larger RBCs known as macrocytes, as well as cellular abnormalities in the bone marrow. Reduced white blood cell and platelet counts are two more test results linked to megaloblastic anemia.

B12 is also necessary for nerve function, and a lack of it can induce neuropathy, which causes tingling and numbness in the hands and feet of those who are affected.

Folate is required for cell division, which occurs in the developing fetus. In a growing fetus, a lack of folate during early pregnancy can raise the chance of neural tube abnormalities such spina bifida.

B12 and folate deficiency is most commonly caused by not getting enough of the vitamins through diet or supplements, poor absorption, or increased requirement, as observed during pregnancy:

  • Dietary deficiencies are uncommon in the United States since many meals and beverages are fortified with vitamins that the body stores. Adults normally have many years' worth of vitamin B12 and around three months' worth of folate stored in their liver. Dietary deficiencies normally do not manifest symptoms until the body's vitamin supplies have been exhausted. Vegans and their breast-fed infants can suffer from B12 deficiency.
  • Inadequate absorption—the absorption of vitamin B12 is a multi-step process. B12 is normally released from food by stomach acid and then bound to intrinsic factor, a protein produced by parietal cells in the stomach, in the small intestine. After being absorbed by the small intestine and bound by carrier proteins, the B12-IF complex reaches the blood. B12 absorption is hampered if any of these processes are disrupted by a disease or condition.
  • Increased demand—this can occur as a result of a range of diseases and disorders. When a woman is pregnant or nursing, in early childhood, with malignancies, or with chronic hemolytic anemias, there is an increased demand for folate.

Lab tests often ordered with a Vitamin B12 and Folate panel test:

  • Complete Blood Count
  • Methylmalonic Acid
  • Homocysteine
  • Vitamin B1
  • Vitamin B3
  • Vitamin B5
  • Vitamin B6
  • Vitamin B7
  • Intrinsic Factor Antibody
  • Parietal Cell Antibody
  • Reticulocyte Count

Conditions where a Vitamin B12 and Folate panel test is recommended:

  • Neural Tube Defects
  • Vitamin B12 and Folate Deficiencies
  • Anemia
  • Alcoholism
  • Malnutrition
  • Celiac Disease
  • Malabsorption
  • Neuropathy
  • Inflammatory Bowel Disease

How does my health care provider use a Vitamin B12 and Folate panel test?

Separate tests for vitamin B12 and folate are frequently used in conjunction to detect deficiencies and to aid in the diagnosis of anemias such as pernicious anemia, an inflammatory condition that inhibits B12 absorption.

B12 and folate are two vitamins that the body cannot generate and must be obtained from the diet. They're needed for red blood cell creation, tissue and cell repair, and DNA synthesis, which is the genetic material in cells. B12 is required for normal nerve function.

B12 and folate tests can also be used to assess someone who is experiencing mental or behavioral changes, especially in the elderly. A B12 test can be ordered with or without folate, as well as with other screening laboratory tests like a complete blood count, comprehensive metabolic panel, antinuclear antibody, C-reactive protein, and rheumatoid factor, to help determine why a person is exhibiting signs and symptoms of a nerve disorder.

B12 and folate tests can also be performed in conjunction with a variety of other tests to assess a person's overall health and nutritional status if they have signs and symptoms of substantial malnutrition or dietary malabsorption. People with alcoholism, liver disease, stomach cancer, or malabsorption diseases including celiac disease, inflammatory bowel disease, or cystic fibrosis may fall into this category.

Testing may be performed to assess the success of treatment in patients with known B12 and folate deficits. This is especially true for people who cannot absorb B12 and/or folate effectively and must be treated for the rest of their lives.

Folate levels in the blood's liquid part might fluctuate depending on a person's recent diet. Because red blood cells contain 95 percent of circulating folate, a test to evaluate folate levels inside RBCs could be employed instead of or in addition to the serum test. Some doctors believe that the RBC folate test is a better predictor of long-term folate status and is more clinically useful than serum folate, however there is no consensus on this.

Homocysteine and methylmalonic acid are two more laboratory tests that can be used to detect B12 and folate deficits. In B12 deficiency, both homocysteine and MMA are high, whereas in folate deficit, only homocysteine, not MMA, is elevated. This distinction is critical because treating anemia with folate treats the anemia but not the brain damage, which may be irreparable.

What do my Vitamin B12 and Folate test results mean?

Normal B12 and folate levels may indicate that a person does not suffer from a deficiency and that the signs and symptoms are caused by something else. Normal levels, on the other hand, may indicate that a person's stored B12 and/or folate has not yet been depleted.

A health practitioner may request a methylmalonic acid test as an early sign of B12 insufficiency if a B12 level is normal but a deficiency is still suspected.

A low B12 and/or folate level in a person with signs and symptoms implies a deficiency, although it does not always indicate the severity of the anemia or related neuropathy. Additional tests are frequently performed to determine the source of the deficit. Low B12 or folate levels can be caused by a variety of factors, including:

Dietary folate or B12 deficiency is uncommon in the United States. It can be evident in people who are malnourished in general and vegans who do not eat any animal products. Folate deficiency has become extremely rare since the development of fortified cereals, breads, and other grain products.

Both B12 and folate deficits can be caused by diseases that prevent them from being absorbed in the small intestine. These may include the following:

  • Pernicious anemia.
  • Celiac disease
  • Crohn's disease and ulcerative colitis
  • Bacterial overgrowth or the presence of parasites in the intestines, such as tapeworms
  • Long-term usage of antacids or H2 proton pump inhibitors reduces stomach acid production.
  • Absorption can be considerably reduced by surgery that removes part of the stomach or the intestines, such as gastric bypass.
  • Insufficiency of the pancreas
  • Chronic alcoholism or heavy drinking
  • Some treatments, such as omeprazole, metformin, methotrexate, and/or anti-seizure medications like phenytoin.
  • Increased requirement for healthy fetal development, all pregnant women require an increased amount of folate and are advised to consume 400 micrograms of folic acid every day. People who have cancer that has spread or who have chronic hemolytic anemia require more folate.
  • Smoking

If a person is taking supplements to treat a B12 or folate deficiency, normal or higher findings indicate that the treatment is working.

High amounts of B12 are uncommon, and they aren't routinely evaluated clinically. If a person has a condition such chronic myeloproliferative neoplasm, diabetes, heart failure, obesity, AIDS, or severe liver disease, their vitamin B12 level may be elevated. High B12 levels can also be caused by using estrogens, vitamin C, or vitamin A.

A lack of folate can cause macrocytic anemia, a condition in which red blood cells are bigger than normal. Megaloblastic anemia is a kind of macrocytic anemia marked by the generation of fewer but larger RBCs known as macrocytes, as well as cellular abnormalities in the bone marrow. Reduced white blood cell and platelet counts are two more test results linked to megaloblastic anemia.

Folate is required for cell division, which occurs in the developing fetus. In a growing fetus, a lack of folate during early pregnancy can raise the chance of neural tube abnormalities such spina bifida.

Folate deficiency is most commonly caused by inadequate intake of the vitamin through diet or supplements, poor absorption, or increased bodily requirement, as observed during pregnancy:

  • Dietary deficiencies are uncommon in the United States since many meals and beverages are fortified with vitamins that the body stores. Adults normally have around three months' worth of folate stored in their liver. Dietary deficiencies normally do not manifest symptoms until the body's vitamin supplies have been exhausted.
  • Increased demand—this can occur as a result of a range of diseases and disorders. When a woman is pregnant or nursing, in early childhood, with malignancies, or with chronic hemolytic anemias, there is an increased demand for folate.

Lab tests often ordered with a Folate test:

  • Complete Blood Count
  • Methylmalonic Acid
  • Homocysteine
  • Vitamin B1
  • Vitamin B3
  • Vitamin B5
  • Vitamin B6
  • Vitamin B7
  • Vitamin B12
  • Intrinsic Factor Antibody
  • Parietal Cell Antibody
  • Reticulocyte Count

Conditions where a Folate test is recommended:

  • Neural Tube Defects
  • Vitamin B12 and Folate Deficiencies
  • Anemia
  • Alcoholism
  • Malnutrition
  • Celiac Disease
  • Malabsorption
  • Neuropathy
  • Nervous System Disorders
  • Inflammatory Bowel Disease

How does my health care provider use a Folate test?

Separate tests for vitamin B12 and folate are frequently used in conjunction to detect deficiencies and to aid in the diagnosis of anemias such as pernicious anemia, an inflammatory condition that inhibits B12 absorption.

B12 and folate are two vitamins that the body cannot generate and must be obtained from the diet. They're needed for red blood cell creation, tissue and cell repair, and DNA synthesis, which is the genetic material in cells. B12 is required for normal nerve function.

B12 and folate tests can also be used to assess someone who is experiencing mental or behavioral changes, especially in the elderly. A B12 test can be ordered with or without folate, as well as with other screening laboratory tests like a complete blood count, comprehensive metabolic panel, antinuclear antibody, C-reactive protein, and rheumatoid factor, to help determine why a person is exhibiting signs and symptoms of a nerve disorder.

B12 and folate tests can also be performed in conjunction with a variety of other tests to assess a person's overall health and nutritional status if they have signs and symptoms of substantial malnutrition or dietary malabsorption. People with alcoholism, liver disease, stomach cancer, or malabsorption diseases including celiac disease, inflammatory bowel disease, or cystic fibrosis may fall into this category.

Testing may be performed to assess the success of treatment in patients with known B12 and folate deficits. This is especially true for people who cannot absorb B12 and/or folate effectively and must be treated for the rest of their lives.

Folate levels in the blood's liquid part might fluctuate depending on a person's recent diet. Because red blood cells contain 95 percent of circulating folate, a test to evaluate folate levels inside RBCs could be employed instead of or in addition to the serum test. Some doctors believe that the RBC folate test is a better predictor of long-term folate status and is more clinically useful than serum folate, however there is no consensus on this.

Homocysteine and methylmalonic acid are two more laboratory tests that can be used to detect B12 and folate deficits. In B12 deficiency, both homocysteine and MMA are high, whereas in folate deficit, only homocysteine, not MMA, is elevated. This distinction is critical because treating anemia with folate treats the anemia but not the brain damage, which may be irreparable.

What do my Folate Serum test results mean?

Normal folate levels may indicate that a person does not suffer from a deficiency and that the signs and symptoms are caused by something else. Normal levels, on the other hand, may indicate that a person's stored folate has not yet been depleted.

A low folate level in a person with signs and symptoms implies a deficiency, although it does not always indicate the severity of the anemia or related neuropathy. Additional tests are frequently performed to determine the source of the deficit. Low folate levels can be caused by a variety of factors.

Dietary folate deficiency is uncommon in the United States. It can be evident in people who are malnourished in general and vegans who do not eat any animal products. Folate deficiency has become extremely rare since the development of fortified cereals, breads, and other grain products.

Folate deficits can be caused by diseases that prevent them from being absorbed in the small intestine. These may include the following:

  • Pernicious anemia.
  • Celiac disease
  • Crohn's disease and ulcerative colitis
  • Bacterial overgrowth or the presence of parasites in the intestines, such as tapeworms
  • Long-term usage of antacids or H2 proton pump inhibitors reduces stomach acid production.
  • Absorption can be considerably reduced by surgery that removes part of the stomach or the intestines, such as gastric bypass.
  • Insufficiency of the pancreas
  • Chronic alcoholism or heavy drinking
  • Some treatments, such as metformin, omeprazole, methotrexate, or anti-seizure medications like phenytoin.
  • Increased requirement for healthy fetal development, all pregnant women require an increased amount of folate and are advised to consume 400 micrograms of folic acid every day. People who have cancer that has spread or who have chronic hemolytic anemia require more folate.
  • Smoking

If a person is taking supplements to treat a folate deficiency, normal or higher findings indicate that the treatment is working.

Description: A Folate RBC test measures the levels of folic acid within your red blood cells. These results can be used to determine a folate deficiency and evaluate a person's nutritional status. Anemia and Neuropathy can also be evaluated using the results from this test.

Collection Method: Blood Draw

Specimen Type: Whole Blood

Test Preparation: No preparation required

When is a Folate RBC test ordered?

When a complete blood count and/or blood smear, performed as part of a health checkup or anemia evaluation, reveal a low red blood cell count with the presence of big RBCs, B12 and folate levels may be ordered. A high mean corpuscular volume, in particular, implies that the RBCs are enlarged.

When a person exhibits the following signs and symptoms of a deficit, testing for folate levels may be necessary.

  • Diarrhea
  • Dizziness
  • Muscle weakness, fatigue
  • Appetite loss.
  • Skin that is pale
  • Irregular heartbeats, rapid heart rate
  • Breathing problems
  • Tongue and mouth ache
  • In the feet, hands, arms, and legs, there is tingling, numbness, and/or burning 
  • Confusion or obliviousness
  • Paranoia

When a person is at risk of deficiency, such as those with a history of malnutrition or a condition associated to malabsorption, folate testing may be ordered.

Individuals being treated for malnutrition or a folate deficit may have these tests done on a frequent basis to see how effective their treatments are. This could be part of a long-term therapy plan for people who have a disease that causes chronic deficiency.

What does a Folate RBC test check for?

The B complex of vitamins includes vitamins including vitamin B12 and folate. They are required for the creation of normal red blood cells, tissue and cell repair, and the synthesis of DNA, the genetic material in cells. Both are nutrients that the body cannot make and must be obtained from the diet.

Vitamin B9 tests, also known as folate tests, diagnose vitamin deficiencies by measuring vitamin levels in the liquid section of the blood. The amount of folate in red blood cells is sometimes tested as well.

Folate is a naturally occurring form of the vitamin, whereas folic acid is a supplement that can be added to foods and beverages. Leafy green vegetables, dry beans and peas, citrus fruits, yeast, and liver all contain it. Vitamin B12, also known as cobalamin, can be found in animal-based foods such red meat, fish, poultry, milk, yogurt, and eggs. Fortified cereals, breads, and other grain products have become key sources of B12 and folate in recent years

Description: A Ferritin test is a blood test that measures Ferritin levels in your blood’s serum to evaluate the level of iron stored in your body.

Also Known As: Ferritin Serum Test, Ferritin Test, Ferritin Blood Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Ferritin test ordered?

When a CBC test’s implies iron deficiency anemia due to small red blood cells or low hematocrit and hemoglobin levels, the ferritin test, and other iron tests, may be requested, even if other clinical symptoms have not yet arisen.

There are frequently no physical symptoms in the early stages of iron insufficiency. Symptoms rarely develop before hemoglobin falls below dangerous levels. However, when the iron deficit continues, symptoms emerge, prompting a doctor to order ferritin and other iron-related testing. The following are the most prevalent symptoms of iron deficiency anemia:

  • Chronic tiredness/fatigue
  • Weakness
  • Dizziness
  • Headaches
  • Skin that is pale

Shortness of breath, ringing in the ears, sleepiness, and irritability may occur as iron levels are reduced. Chest pain, headaches, limb pains, shock, and even heart failure may occur as the anemia worsens. Learning impairments can occur in children. There are some symptoms that are specific to iron deficiency, in addition to the usual signs of anemia. Pica, a burning feeling in the tongue or a smooth tongue, ulcers at the corners of the mouth, and spoon-shaped finger- and toe-nails are only a few of the symptoms.

When iron overload is suspected, a ferritin level may be requested. Iron overload symptoms differ from person to person and tend to worsen over time. They are caused by an excess of iron in the blood and tissues. Among the signs and symptoms are:

  • Joint discomfort
  • Weakness and exhaustion
  • Loss of weight
  • Energy deficiency
  • Pain in the abdomen
  • Suffering from a lack of sexual desire
  • Hair loss on the body
  • Congestive heart failure is an example of a cardiac issue

Other iron tests including a genetic test for hereditary hemochromatosis may be conducted to confirm the existence of iron excess.

What does a Ferritin blood test check for?

Ferritin is an iron-containing protein that stores iron in cells in its most basic form. The amount of total iron stored in the body is reflected in the little amount of ferritin released into the blood. This test determines how much ferritin is present in the blood.

About 70% of the iron consumed by the body is integrated into the hemoglobin of red blood cells in healthy humans. The remaining 30% is stored primarily as ferritin or hemosiderin, which is a combination of iron, proteins, and other elements. Hemosiderin and ferritin are typically found in the liver, although they can also be found in the bone marrow, spleen, and skeletal muscles.

Iron stores are depleted and ferritin levels fall when available iron is insufficient to meet the body's needs. This can happen owing to a lack of iron, poor absorption, or an increased need for iron, such as during pregnancy or if you have a condition that causes persistent blood loss. Before any indicators of iron shortage appear, significant loss of iron reserves may occur.

When the body absorbs more iron than it needs, iron storage and ferritin levels rise. Chronic iron absorption causes a gradual buildup of iron compounds in organs, which can eventually lead to organ malfunction and failure. Even on a typical diet, this happens in hemochromatosis, a hereditary disorder in which the body absorbs too much iron.

Lab tests often ordered with a Ferritin test:

  • Complete Blood Count
  • Iron Total
  • Iron Total and Total Iron binding capacity
  • Transferrin
  • Comprehensive Metabolic Panel
  • Lipid Panel
  • Zinc Protoporphyrin

Conditions where a Ferritin test is recommended:

  • Anemia
  • Hemochromatosis
  • Lead poisoning
  • Pregnancy
  • Restless Leg Syndrome

How does my health care provider use a Ferritin test?

The ferritin test is used to determine the amount of iron a person has in their body. To determine the existence and severity of iron shortage or iron overload, the test is sometimes ordered in conjunction with an iron test and a TIBC test.

One source of iron overload can be the use of iron supplements.

What does my ferritin lab test result mean?

Ferritin levels are frequently measured alongside other iron tests.

Ferritin levels are low in iron deficient people and high in people who have hemochromatosis or have had several blood transfusions.

Ferritin is an acute phase reactant that can be elevated in persons who have inflammation, liver illness, chronic infection, autoimmune disorders, or cancer. Ferritin isn't commonly utilized to detect or monitor these problems.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Description: The gastrin test is used to measure gastrin, a hormone that controls stomach acid. The test measures gastrin levels in your blood’s serum.

Also Known As: Gastrinomas Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Overnight fasting (12 hours) required

When is a Gastrin test ordered?

When a patient experiences diarrhea, abdominal pain, and/or recurring peptic ulcers that do not improve after treatment and that the doctor feels are brought on by excessive gastrin production, a gastrin test may be recommended. When a patient's gastrin level is moderately increased and a doctor feels they may have a gastrinoma, they may be given a gastrin stimulation test.

A periodic gastrin test may be requested as a screening test to check for recurrence after a gastrin-producing tumor has been excised.

What does a Gastrin test check for?

The "G-cells" in the antrum, a region of the stomach, create the hormone called "gastrin." During the digestion process, it controls the amount of acid produced in the stomach. To assess a person with recurrent peptic ulcers and/or other severe gastrointestinal symptoms, this test analyzes the level of gastrin in the blood.

The antrum of the stomach swells as food is consumed, and the meal itself causes gastrin to be released. The production of stomach acid is then stimulated by the hormone gastrin. Acidity aids in food digestion, and when it increases, it eventually inhibits the release of gastrin. Low levels of gastrin are often produced by this feedback system, especially while a person is fasting. An excess of gastrin and stomach acid can be brought on by uncommon disorders such G-cell hyperplasia and gastrinomas, including Zollinger-Ellison syndrome. Aggressive peptic ulcers that are challenging to treat may result from this.

Gastrinomas are tumors that make gastrin. One or more gastrinomas can result in ZE syndrome, which is characterized by excessive gastrin levels, significantly increased stomach acid production, and peptic ulcers. Despite the fact that the pancreas' endocrine cells don't typically produce gastrin, gastrinomas frequently develop there. More than half of them are cancerous, leading to cancer that can spread to different organs including the liver. Large amounts of gastrin can be produced by even the smallest tumors.

Lab tests often ordered with a Gastrin test:

  • Helicobacter Pylori (H. Pylori)
  • Gastric Acid

Conditions where a Gastrin test is recommended:

  • Endocrine Syndromes
  • Gastrinomas

How does my health care provider use a Gastrin test?

The main purpose of the gastrin test is to identify cases of excessive gastrin and stomach acid production. It is used to assist in the diagnosis of Zollinger-Ellison syndrome, hyperplasia of G-cells, and gastrinomas, which are gastrin-producing tumors. The stomach's G-cells are specialized cells that create gastrin, which boosts the production of gastric acid.

After a gastrinoma has been surgically removed, a gastrin test may be used to check for recurrence.

Therefore, if the initial gastrin test result is moderately but not significantly high and the healthcare professional feels that a person's symptoms are brought on by a gastrinoma, a gastrin stimulation test may be conducted to provide additional information. This process entails taking a baseline sample of gastrin, administering a drug to the patient to increase gastrin synthesis, and then taking more blood samples at certain intervals for gastrin testing. After secretin administration, the other sources of high gastrin won't exhibit a rise.

To aid in the diagnosis of ZE syndrome, a measurement of the pH level of gastric acid may occasionally be requested before, during, or after a gastrin test.

What do my Gastrin test results mean?

It is uncommon to be concerned about low or normal blood levels of gastrin.

A number of diseases and illnesses, including ZE syndrome, pernicious anemia, G-cell hyperplasia, chronic atrophic gastritis, chronic kidney failure, and pyloric blockage, can cause somewhat elevated levels.

A person is likely to have ZE syndrome and one or more gastrinomas if their gastrin levels are significantly elevated in symptomatic persons and increase significantly after a gastrin stimulation test. In order to find the gastrinomas, imaging tests may be prescribed as a follow-up to elevated gastrin concentrations. Both the size and the number of tumors have no effect on how much gastrin is produced. Large volumes of gastrin can be produced by even small tumors.

Following surgical resection of a gastrinoma, low-grade gastrin levels that later rise could indicate a return of the tumor. Concentrations that remain elevated following treatment may be a sign that it wasn't entirely successful.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Description: Homocysteine is an amino acid that is present in every cell. There is a small amount present as it is an amino acid that changes quickly into other needed products in the body.

Also Known As: Homocysteine Cardiac Risk Test, Homocysteine Blood Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Fasting for at least 8 hours is preferred

When is a Homocysteine test ordered?

When a doctor feels a person may be deficient in vitamin B12 or folate, he or she may request this test. At first, the signs and symptoms are vague and ambiguous. People who have an early deficit may be diagnosed before they show any visible symptoms. Other persons who are impacted may experience a range of moderate to severe symptoms, including:

  • Diarrhea
  • Dizziness
  • Weakness and exhaustion
  • Appetite loss
  • Paleness
  • Heart rate that is quite fast
  • Breathing problems
  • Tongue and mouth ache
  • In the feet, hands, arms, and legs, there is tingling, numbness, and/or burning

Depending on an individual's age and other risk factors, homocysteine may be requested as part of determining a person's risk of developing cardiovascular disease. It may also be ordered after a heart attack or stroke to aid in treatment planning.

When newborn screening identifies an increased level of methionine or if an infant or kid shows signs and symptoms of homocystinuria, this test may be ordered. Babies with this illness will appear normal at birth, but if left untreated, they will develop symptoms such as a displaced lens in the eye, a long slender build, long thin fingers, and skeletal abnormalities within a few years.

What does a Homocysteine blood test check for?

Homocysteine is an amino acid that is found in trace amounts in all of the body's cells. The body generally converts homocysteine to other compounds fast. Because vitamins B6, B12, and folate are required for homocysteine metabolism, elevated levels of the amino acid could indicate a vitamin deficit. The level of homocysteine in the blood is determined by this test.

Increased homocysteine levels have also been linked to an increased risk of coronary heart disease, stroke, peripheral vascular disease, and artery hardening. Homocysteine has been linked to cardiovascular disease risk through a variety of processes, including damage to blood vessel walls and support for the production of abnormal blood clots, but no direct linkages have been established. Several studies have also found no benefit or reduction in CVD risk with folic acid and B vitamin supplementation. The American Heart Association does not believe it to be a significant risk factor for heart disease at this time.

Homocysteine levels in the blood can also be dramatically increased by a rare genetic disorder known as homocystinuria. In homocystinuria, one of multiple genes is mutated, resulting in a defective enzyme that prevents the normal breakdown of methionine, the precursor of homocysteine. Methionine is one of the eleven necessary amino acids that the body cannot make and must therefore be obtained from food.

Homocysteine and methionine build up in the body without the necessary enzyme to break them down. Babies born with this condition appear normal at birth, but develop symptoms such as a long slender build, a dislocated lens in the eye, long thin fingers, osteoporosis, skeletal abnormalities, and a significantly increased risk of thromboembolism and atherosclerosis, which can lead to premature CVD within a few years.

In addition to intellectual disability, mental illness, a little low IQ, behavioral issues, and seizures, artery blockages can induce intellectual disability, mental illness, and seizures. Some of them can be avoided if homocystinuria is diagnosed early, which is why all states screen neonates for the disease.

Lab tests often ordered with a Homocysteine test:

  • Vitamin B12
  • Folate
  • MTHFR Mutation
  • Intrinsic Factor Antibody

Conditions where a Homocysteine test is recommended:

  • Vitamin B12 and Folate Deficiency
  • Heart Attack
  • Heart Disease
  • Stroke

How does my health care provider use a Homocysteine test?

The homocysteine test can be used in a variety of ways, including:

A homocysteine test may be ordered by a doctor to see if a person is deficient in vitamin B12 or folate. Before B12 and folate tests are abnormal, the homocysteine level may be raised. Homocysteine testing may be recommended by some health professionals in malnourished people, the elderly, who absorb less vitamin B12 from their diet, and people who have poor nutrition, such as drug or alcohol addicts.

For those at high risk of a stroke or heart attack, homocysteine testing may be requested as part of a health screening. It could be beneficial for someone who has a family history of coronary artery disease but no other recognized risk factors like smoking, high blood pressure, or obesity. However, because the specific role of homocysteine in the course of cardiovascular disease is unknown, the screening test's efficacy continues to be questioned.

If a health professional believes that an infant or kid has homocystinuria, tests for both urine and blood homocysteine can be utilized to assist diagnose the genetic condition. As part of their newborn screening in the United States, all babies are regularly tested for excess methionine, a symptom of homocystinuria. If a baby's test results are positive, urine and blood homocysteine tests are frequently used to confirm the results.

What do my homocysteine test results mean?

Homocysteine levels may be high in cases of suspected malnutrition, vitamin B12, or folate insufficiency. If a person does not consume enough B vitamins and/or folate through diet or supplements, the body may be unable to convert homocysteine into forms that the body can use. The level of homocysteine in the blood may rise in this scenario.

According to studies conducted in the mid- to late-1990s, those with high homocysteine levels have a substantially higher risk of heart attack or stroke than those with normal levels. The study of the relationship between excessive homocysteine levels and heart disease is still ongoing. However, considering that multiple trials studying folic acid and B vitamin supplementation have found no benefit or reduction in CVD risk, the use of homocysteine levels for risk assessment of cardiovascular disease, peripheral vascular disease, and stroke is now questionable.

A 2012 research study using various datasets, including 50,000 persons with coronary heart disease, called into question the possibility of a cause-and-effect relationship between homocysteine levels and heart disease. Although the American Heart Association recognizes a link between homocysteine levels and heart attack/stroke survival rates, it does not consider high homocysteine to be a major CVD risk factor.

While the AHA does not advocate for widespread use of folic acid and B vitamins to reduce the risk of heart attack and stroke, it does advocate for a balanced, nutritious diet and advises doctors to consider total risk factors as well as nutrition when treating cardiovascular disease.

Significantly elevated homocysteine concentrations in the urine and blood indicate that an infant is likely to have homocystinuria and need additional testing to confirm the reason of the increase.

Description: The Intrinsic Factor Blocking antibody test is a blood test used to detect antibodies to Intrinsic Factor, a protein complex created by your stomach lining to help your body absorb Vitamin B12.

Also Known As: Intrinsic Factor Antibody test, IF Antibody Test, IF Antibody Type 1 Test, IF Antibody Type 2 Test,

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is an Intrinsic Factor Blocking Antibody test ordered?

It is uncommon to order the intrinsic factor antibody test. When a person has symptoms of pernicious anemia with a vitamin B12 deficiency, such as when they exhibit the following signs and symptoms:

  • Paleness
  • weakness, exhaustion
  • tingling and numbness in the hands and/or feet
  • larger-than-normal red blood cells; occasionally, large RBCs are found before the other symptoms become apparent, for example, during a routine complete blood count test for a health examination.

Testing for vitamin B12, folate, and methylmalonic acid is typically prompted by these findings.

An IF antibody test is often requested when a person's vitamin B12 level is low and their levels of homocysteine and methylmalonic acid are elevated.

What does an Intrinsic Factor Blocking Antibody test check for?

Intrinsic factor antibodies are immune system-produced proteins linked to pernicious anemia. This examination finds blood-circulating intrinsic factor antibodies.

A type of specialized stomach wall cell known as parietal cells produces the protein known as intrinsic factor. Stomach acids release vitamin B12 from food during digestion, and it then binds with intrinsic factor to create a complex. For vitamin B12 to be absorbed in the small intestine, this complex must first form.

Vitamin B12 is crucial for the synthesis of red blood cells in addition to its responsibilities in the brain and nervous system. Vitamin B12 is generally not absorbed if there is insufficient intrinsic factor, which prevents the body from producing enough healthy red blood cells and results in anemia. The amount of neutrophils and platelets may fall in addition to anemia.

Pernicious anemia is anemia brought on by a deficiency of intrinsic factor. This disorder is primarily autoimmune in nature and results from the body's immune system producing antibodies against parietal cells and/or the intrinsic factor. These antibodies have the potential to harm parietal cells, obstruct the generation of intrinsic factor, or stop intrinsic factor from performing its biological role.

The laboratory can check for two different IF antibodies:

The most common test is for intrinsic factor blocking antibody, because it is more specific for pernicious anemia.

Antibody that binds intrinsic factors prevents the absorption of the combination of intrinsic factors and vitamin B12

Lab tests often ordered with an Intrinsic Factor Blocking Antibody test:

  • Vitamin B12
  • Folate
  • Methylmalonic Acid
  • Gastrin
  • Parietal Cell Antibody
  • Homocysteine
  • Complete Blood Count

Conditions where an Intrinsic Factor Blocking Antibody test is recommended:

  • Vitamin B12 and Folate Deficiencies
  • Anemia
  • Autoimmune Disease
  • Neuropathy

How does my health care provider use an Intrinsic Factor Blocking Antibody test?

A vitamin B12 deficiency's underlying cause and the presence of pernicious anemia can both be determined with the use of an intrinsic factor antibody test.

Lack of intrinsic factor results in vitamin B12 insufficiency, which is the cause of pernicious anemia. The primary cause of this illness is when the body's immune system creates antibodies against its own tissues and targets the parietal cells or intrinsic factor. These antibodies have the potential to harm parietal cells, obstruct the generation of intrinsic factor, or stop intrinsic factor from performing its biological role. Vitamin B12 and intrinsic factor combine to generate a compound that facilitates absorption in the small intestine.

In most cases, IF antibody testing is utilized as a follow-up procedure after other laboratory tests, including as a vitamin B12 test, a methylmalonic acid test, and a complete blood count, have determined that a person has a vitamin B12 deficiency with accompanying anemia and/or neuropathy.

It can help establish a diagnosis when combined with a test for antibodies against parietal cells.

There are two IF antibodies that could be examined:

anti-intrinsic factor antibody that prevents vitamin B12 from attaching to intrinsic factor. This is the one that is typically examined since it is more specific for pernicious anemia.

Antibody that binds to or precipitates intrinsic factors and prevents the small intestine from absorbing the intrinsic factor-vitamin B12 combination.

What do my Intrinsic Factor Blocking Antibody test results mean?

When making a diagnosis, the results of other laboratory tests are frequently combined with the results of intrinsic factor antibody tests. It is most likely that someone has pernicious anemia if they have elevated IF antibodies, elevated methylmalonic acid and homocysteine levels, and low vitamin B12 levels.

The absence of pernicious anemia is not always indicated by a negative test result. Up to 50% of persons who are impacted won't have IF antibodies. In the absence of them, the doctor may request a parietal cell antibody test to aid in making the diagnosis. Antibodies against parietal cells are less focused than IF antibodies. About 90% of people with pernicious anemia have them, but they can also be found in a wide range of other diseases and in approximately 10% of the general public.

Description: Iron and Total Iron Binding Capacity is a blood panel used to determine iron levels in your blood, your body’s ability to transport iron, and help diagnose iron-deficiency and iron overload.

Also Known As: Serum Iron Test, Serum Fe Test, Iron Binding Capacity Test, IBC Test, Serum Iron-Binding Capacity Siderophilin Test, TIBC Test, UIBC Test, Iron Lab Test, TIBC Blood test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Iron and Total Iron Binding Capacity test ordered?

When a doctor feels that a person's symptoms are caused by iron overload or poisoning, an iron and TIBC test, as well ferritin assays, may be done. These may include the following:

  • Joint discomfort
  • Weakness and exhaustion
  • Energy deficiency
  • Pain in the abdomen
  • Suffering from a lack of sexual desire
  • Problems with the heart

When a child is suspected of ingesting too many iron tablets, a serum iron test is required to detect the poisoning and to determine its severity.

A doctor may also request iron and TIBC when the results of a standard CBC test are abnormal, such as a low hematocrit or hemoglobin, or when a doctor suspects iron deficiency based on signs and symptoms such as:

  • Chronic tiredness/fatigue
  • Dizziness
  • Weakness
  • Headaches
  • Skin that is pale

What does a Iron and Total Iron Binding Capacity blood test check for?

Iron is a necessary ingredient for survival. It is a vital component of hemoglobin, the protein in red blood cells that binds and releases oxygen in the lungs and throughout the body. It is required in small amounts to help form normal red blood cells and is a critical part of hemoglobin, the protein in RBCs that binds oxygen in the lungs and releases it as blood circulates to other parts of the body.

By detecting numerous components in the blood, iron tests are ordered to determine the quantity of iron in the body. These tests are frequently ordered at the same time, and the data are analyzed together to determine the diagnosis and/or monitor iron deficiency or overload.

The level of iron in the liquid component of the blood is measured by serum iron.

Total iron-binding capacity is a measurement of all the proteins in the blood that may bind to iron, including transferrin.

The percentage of transferrin that has not yet been saturated is measured by the UIBC. Transferrin levels are also reflected in the UIBC.

Low iron levels can cause anemia, resulting in a decrease in the production of microcytic and hypochromic RBCs. Large amounts of iron, on the other hand, might be hazardous to the body. When too much iron is absorbed over time, iron compounds build up in tissues, particularly the liver, heart, and pancreas.

Normally, iron is absorbed from food and distributed throughout the body by binding to transferrin, a liver protein. About 70% of the iron delivered is used in the synthesis of hemoglobin in red blood cells. The rest is stored as ferritin or hemosiderin in the tissues, with minor amounts being utilized to make other proteins like myoglobin and enzymes.

Insufficient intake, limited absorption, or increased dietary requirements, as observed during pregnancy or with acute or chronic blood loss, are all signs of iron deficiency. Excessive intake of iron pills can cause acute iron overload, especially in children. Excessive iron intake, genetic hemochromatosis, multiple blood transfusions, and a few other disorders can cause chronic iron overload.

Lab tests often ordered with a Iron and Total Iron Binding Capacity test:

  • Complete Blood Count
  • Ferritin
  • Transferrin
  • Zinc Protoporphyrin

Conditions where a Iron and Total Iron Binding Capacity test is recommended:

  • Anemia
  • Hemochromatosis

How does my health care provider use a Iron and Total Iron Binding Capacity test?

The amount of circulating iron in the blood, the capacity of the blood to carry iron, and the amount of stored iron in tissues can all be determined by ordering one or more tests. Testing can also assist distinguish between different types of anemia

The level of iron in the blood is measured by serum iron.

Total iron-binding capacity is a measurement of all the proteins in the blood that may bind to iron, including transferrin. The TIBC test is a useful indirect assessment of transferrin because it is the predominant iron-binding protein. In response to the requirement for iron, the body generates transferrin. Transferrin levels rise when iron levels are low, and vice versa. About one-third of the binding sites on transferrin are used to transport iron in healthy humans.

The reserve capacity of transferrin, or the part of transferrin that has not yet been saturated, is measured by UIBC. Transferrin levels are also reflected in the UIBC.

The iron test result, as well as TIBC or UIBC, are used to calculate transferrin saturation. It represents the proportion of transferrin that is iron-saturated.

Ferritin is the major storage protein for iron inside cells, and serum ferritin represents the quantity of stored iron in the body.

These tests are frequently ordered together, and the results can assist the doctor figure out what's causing the iron deficit or overload.

Additional information about iron

A balance between the quantity of iron received into the body and the amount of iron lost is required to maintain normal iron levels. Because a tiny quantity of iron is lost each day, a deficiency will develop if too little iron is consumed. In healthy persons, there is usually enough iron to prevent iron deficiency and/or iron deficiency anemia, unless they eat a bad diet. There is a greater need for iron in some circumstances. People who have persistent gut bleeding or women who have heavy menstrual periods lose more iron than they should and can develop iron deficiency. Females who are pregnant or breastfeeding lose iron to their babies and may develop an iron shortage if they do not consume enough supplemental iron. Children may require additional iron, especially during periods of rapid growth, and may suffer iron shortage.

Low serum iron can also arise when the body is unable to adequately utilize iron. The body cannot correctly utilize iron to generate additional red cells in many chronic disorders, particularly malignancies, autoimmune diseases, and chronic infections. As a result, transferrin production slows, serum iron levels drop because little iron is absorbed from the stomach, and ferritin levels rise. Malabsorption illnesses like sprue syndrome can cause iron deficiency.

Description: A Lactate Dehydrogenase or LD test is a blood test that measure the level of the enzyme Lactate Dehydrogenase in your blood’s serum and can be used to detect a wide variety of disorders including liver disease, kidney disease, infections, and pancreatitis.

Also Known As: LD Test, LDH Test, Lactic Acid Dehydrogenase Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Lactate Dehydrogenase test ordered?

When a health practitioner feels that a disease or condition is causing cellular or tissue damage, an LD level, coupled with other tests such as a comprehensive metabolic panel, may be requested. More specific tests, such as alanine transaminase, aspartate aminotransferase, or alkaline phosphatase, may be used to identify the illness and pinpoint which organs are affected if LD is increased. Total LD levels may be ordered at regular intervals to monitor the course and/or resolution of the acute or chronic issue once it has been diagnosed.

When a person has had muscle damage or injury, or when they have signs and symptoms of hemolytic anemia, LD levels may be ordered.

When a person has been diagnosed with cancer, LD testing may be performed on a regular basis.

When a person exhibits signs and symptoms of meningitis, or when there is an accumulation of fluid around the heart, lungs, or abdomen, this test may be recommended.

What does a Lactate Dehydrogenase blood test check for?

Lactate dehydrogenase is an energy-producing enzyme found in nearly all of the body's cells, with the highest concentrations in the heart, liver, muscles, kidneys, lungs, and blood cells; bacteria also produce LD. This test determines the amount of LD in the blood or other bodily fluids.

In the fluid component of the blood, just a little quantity of LD is normally measurable. When cells are injured or destroyed, LD is released into the bloodstream. As a result, an LD blood level is a non-specific indicator of tissue damage elsewhere in the body. It cannot be used to determine the underlying cause or location of cellular damage on its own. It can, however, be used in conjunction with other blood tests to assist diagnose and/or monitor disorders that cause tissue damage, such as liver or blood diseases, or cancer.

Fluid can accumulate or the components of the fluid present can change when there is damage, inflammation, or infection in a specific area of the body, such as the brain, heart, or lungs. The amount of LD in the fluid could help you figure out what's wrong. When a person has bacterial meningitis, for example, LD levels in the cerebrospinal fluid are usually high. The LD test, in combination with other tests, can be used to detect whether fluid buildup around the heart, lungs, or abdominal cavity is caused by injury or inflammation or by an imbalance of fluid pressure inside blood vessels and blood protein levels. Some fluids that can be analyzed using an LD test are listed in the article on Body Fluid Analysis.

Lab tests often ordered with a Lactate Dehydrogenase test:

  • Comprehensive Metabolic Panel
  • Haptoglobin
  • Hepatic Function Panel

Conditions where a Lactate Dehydrogenase test is recommended:

  • Liver Disease
  • Kidney Disease
  • Lung Diseases
  • Heart Disease
  • Heart Attack
  • Anemia
  • Meningitis
  • Pancreatic Diseases
  • Testicular Cancer
  • Ovarian Cancer
  • Lymphoma
  • Leukemia

How does my health care provider use a Lactate Dehydrogenase test?

A lactate dehydrogenase test is a non-specific test that can be used to diagnose a variety of diseases and disorders. When cells are injured or destroyed, LD, an enzyme found in practically all of the body's cells, is released from the cells into the fluid portion of blood. As a result, the presence of LD in the blood is a general sign of tissue and cellular damage. In the presence of certain disorders, the amount of LD may also grow in other types of body fluids.

A blood test for LD may be used:

  • As a broad measure of whether or not acute or chronic tissue injury exists and how severe it is
  • To diagnose and track the progression of illnesses such as anemia and severe infections.
  • To aid in the staging, prognosis, and/or monitoring of cancers such as germ cell tumors, lymphoma, leukemia, melanoma, and neuroblastoma, as well as lymphoma, leukemia, melanoma, and neuroblastoma.

Body fluids are subjected to an LD test for a variety of reasons:

  • To aid in the evaluation of cerebrospinal fluid and the differentiation between bacterial and viral meningitis
  • To identify whether the build up of fluid is related to an injury and inflammation or to an imbalance of pressure within blood vessels and the amount of protein in the blood by evaluating other body fluids such as peritoneal, pleural, or pericardial fluid. This information is useful in determining therapy options.

Other fluids that can be tested using an LD test are included in the article on Body Fluid Analysis.

What do my lactate dehydrogenase test results mean?

LD values that are elevated usually indicate tissue damage. As cellular death begins, LD levels normally climb, peak after a period of time, and then begin to diminish. LD levels are raised in a number of situations, indicating that it has a wide tissue distribution.

Elevated LD levels may be seen with:

  • Hemolytic anemia
  • Pernicious anemia 
  • Infectious mononucleosis
  • Meningitis
  • Encephalitis
  • HIV
  • Sepsis
  • Intestinal and pulmonary infarctions
  • Acute kidney disease
  • Acute hepatitis
  • Acute muscle damage
  • Pancreatitis
  • Fractures of the bones
  • Malignancies of the testicles, lymphoma, or other cancers

A high level of LD in the blood may suggest that cancer treatment has failed. A high level is associated with a poorer prognosis for cancer patients. Moderately high LD blood levels may remain in several chronic and progressive diseases. LD levels that are low or normal do not usually indicate a concern. When a high amount of ascorbic acid is consumed, low levels can occur.

Fluids in the body:

  • Cerebrospinal fluid—a high LD implies bacterial meningitis, whereas a low or normal amount indicates viral meningitis is more likely.
  • Pericardial fluid, peritoneal fluid, or pleural fluid with a high LD is an exudate, while fluid with a low LD is a transudate. Cirrhosis or congestive heart failure are the most common causes of transudates. Exudates can have a variety of causes, and determining the cause usually necessitates additional testing.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.


Description: Methylmalonic Acid, also known as MMA, is a blood test used to detect Vitamin B12 deficiency early on before an individual becomes deficient or when there is a mild deficiency already present. MMA can also be used to diagnose methylmalonic acidemia in newborns.

Also Known As: MMA Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Methylmalonic Acid test ordered?

When a vitamin B12 test result comes back low, an MMA test may be performed, sometimes coupled with a homocysteine test.

Asymptomatic persons with a higher risk of vitamin B12 insufficiency, such as the elderly, or those using certain medicines for a long period, such as Metformin, are also given MMA. If the two tests are not scheduled together, an MMA test may be ordered as a follow-up to an increased homocysteine level.

When a doctor fears that an acutely unwell child has inherited methylmalonic acidemia, MMA testing may be recommended.

What does a Methylmalonic Acid blood test check for?

Methylmalonic acid is a naturally occurring chemical that is required for human metabolism and energy generation. Vitamin B12 aids in the conversion of methylmalonyl CoA to succinyl Coenzyme A in one step of metabolism. If there isn't enough B12, the MMA concentration rises, resulting in an increase in MMA levels in the blood and urine. Methylmalonic acid levels that are high in the blood or urine are a sensitive and early sign of vitamin B12 insufficiency.

Anemia and the formation of big red blood cells can occur as a result of vitamin B12 deficiency over time. It can also induce neuropathy symptoms including numbness and tingling in the hands and feet, as well as mental or behavioral problems like cognitive impairment, disorientation, irritability, and depression in severe cases. Though some patients may have some degree of neuropathy, an increased concentration of MMA may frequently be detected before blood cell alterations and full-blown symptoms appear.

Although the link between MMA and B12 has been recognized for over 40 years, MMA testing is not widely used, and there is no consensus on its clinical relevance. Some doctors believe that MMA is a better indicator of bioavailable B12 than the standard vitamin B12 test since a considerable portion of B12 detected in the blood is bound to proteins and is not biologically active. Others feel that measuring MMA and homocysteine can help detect early and mild B12 insufficiency. Others believe that many moderate deficits diagnosed do not evolve to more serious deficiencies and so do not require identification or treatment.

Methylmalonic acidemia is a rare metabolic condition that affects roughly 1 in 25,000 to 100,000 people. Testing babies for high levels of MMA could help doctors diagnose it. Screening for this disease is required in all 50 states in the United States. This condition prevents babies from converting methylmalonyl Coenzyme A to succinyl Coenzyme A.

Lab tests often ordered with a Methylmalonic Acid test:

  • Vitamin B12
  • Folate
  • Homocysteine
  • Intrinsic Factor Antibody
  • Complete Blood Count (CBC)
  • Reticulocyte Count
  • Parietal Cell Antibody

Conditions where a Methylmalonic Acid test is recommended:

  • Vitamin B12 Deficiency
  • Folate Deficiency
  • Anemia

How does my health care provider use a Methylmalonic Acid test?

The methylmalonic acid test can be used to determine a vitamin B12 deficiency that is mild or early. It can be ordered alone or in conjunction with a homocysteine test as a follow-up to a vitamin B12 test result that falls below the normal range.

MMA is a chemical produced in the body in extremely minute amounts. It is required for metabolism and the creation of energy. Vitamin B12 aids in the conversion of methylmalonyl CoA to succinyl Coenzyme A in one step of metabolism. If there isn't enough B12, the MMA level rises, resulting in an increase in MMA levels in the blood and urine. Methylmalonic acid levels in the blood or urine can be used to detect vitamin B12 insufficiency early.

There are currently no standards for screening asymptomatic adults for vitamin B12 deficiency, however those at high risk without symptoms, such as the elderly or those taking particular drugs for a long time, may require confirmation with MMA and/or homocysteine.

The MMA test is quite sensitive in detecting a B12 deficiency. It is the preferred confirmatory test for a B12 deficiency because it is more specific than homocysteine.

MMA testing may be conducted in some cases to assist detect methylmalonic acidemia, a rare inherited metabolic condition. In all 50 states in the United States, newborn screening programs currently require testing for this disease.

What do my Methylmalonic Acid test results mean?

Early stages of B12 deficiency may be evident if MMA and homocysteine levels are elevated while vitamin B12 levels are mildly diminished. This could indicate a decrease in B12 availability in the tissues.

If only the homocysteine level is high but not the MMA, the person may be deficient in folate. This distinction is critical because treating anemia with folate treats the anemia but not the brain damage, which may be irreparable.

If both MMA and homocysteine levels are within normal limits, a B12 shortage is unlikely.

Infants with the rare hereditary illness methylmalonic acidemia may have moderately to severely high levels of MMA.

Reduced MMA levels are uncommon and are not considered clinically significant.

Description: Reticulocytes are red blood cells that are not fully developed yet. The reticulocyte test is used to measure the amount of underdeveloped red blood cells.

Also Known As: Retic Count Reticulocyte Percent Test, Reticulocyte Index Test, Corrected Reticulocyte Test, Reticulocyte Production Index Test, RPI Test

Collection Method: Blood Draw

Specimen Type: Whole Blood

Test Preparation: No preparation required

When is a Reticulocyte Count test ordered?

A reticulocyte count may be requested in the following situations:

  • A low RBC count, as well as a low hemoglobin and hematocrit, are found on a complete blood count.
  • A doctor wants to check the function of the bone marrow.
  • Paleness, loss of energy, exhaustion, weakness, shortness of breath, and/or blood in the stool are signs and symptoms of anemia or persistent bleeding.
  • A disorder known to impact RBC production, such as iron deficiency anemia, vitamin B12 or folate deficiency, or renal illness, has been recognized and is being treated.
  • A person is receiving radiation or chemotherapy.
  • A bone marrow transplant has been performed.

When a person has an increased quantity of RBCs and an elevated hemoglobin and hematocrit, a blood test is performed to evaluate the degree and pace of RBC overproduction.

What does a Reticulocyte Count blood test check for?

Reticulocytes are young red blood cells that have just been created. The number and/or percentage of reticulocytes in the blood is determined by a reticulocyte test, which is a reflection of recent bone marrow function or activity.

Red blood cells are made in the bone marrow, where blood-forming stem cells differentiate and grow into reticulocytes, which then mature into mature RBCs. When compared to mature RBCs, reticulocytes have a volume of about 24 percent more. Although adult RBCs do not have a nucleus like most other cells in the body, reticulocytes still contain some genetic material. Reticulocytes lose the last traces of RNA as they mature, and most of them are fully matured within a day of being released from the bone marrow into the bloodstream. The reticulocyte count or percentage is an excellent measure of a person's ability to manufacture enough red blood cells in their bone marrow.

RBCs last around 120 days in circulation, and the bone marrow must constantly manufacture new RBCs to replace those that have aged and degraded or have been lost due to hemorrhage. Normally, a steady number of RBCs is maintained in the blood by replacing deteriorated or lost RBCs on a regular basis.

A range of diseases and conditions, including those that cause severe bleeding, can impair the creation of new RBCs and/or their survival. These situations can cause an increase or decrease in the number of RBCs, as well as a change in the reticulocyte count.

Reticulocyte % higher than normal: Anemia is caused by a lack of RBCs in the blood due to acute or chronic bleeding or enhanced RBC breakdown (hemolysis). The body adjusts for this loss or responds to deficiency anemia treatment by increasing RBC production and releasing RBCs into the bloodstream before they mature. When this happens, the number and percentage of reticulocytes in the blood grows until the bone marrow's production capacity is reached or until a sufficient number of RBCs replaces those that were lost.

A lower-than-normal percentage of reticulocytes: When the bone marrow isn't working properly, RBC production can suffer. A bone marrow condition, such as aplastic anemia, can cause this. Other causes that might cause decreased production include liver cirrhosis, kidney disease, cancer treatments such as radiation or chemotherapy, a low amount of the hormone erythropoietin, or dietary shortages such as iron, vitamin B12, or folate. As old RBCs are eliminated from the blood but not entirely replaced, there are fewer RBCs in circulation, poorer hemoglobin and oxygen-carrying capacity, a lower hematocrit, and a lower number of reticulocytes.

Due to excessive RBC production by the bone marrow, both the reticulocyte and RBC counts might occasionally rise. This could be caused by increased erythropoietin production, diseases that cause chronic RBC overproduction (polycythemia vera), or cigarette smoking.

Some medications can increase or reduce the number of reticulocytes in the body.

Lab tests often ordered with a Reticulocyte Count test:

  • Complete Blood Count (CBC)
  • Red Blood Cell Count
  • Hemoglobin
  • Hematocrit
  • Blood Smear
  • Erythropoietin
  • Vitamin B12
  • Folate
  • Haptoglobin
  • G6PD
  • Iron Total
  • Iron and Total Iron Binding Capacity
  • Ferritin

Conditions where a Reticulocyte Count test is recommended:

  • Anemia
  • Bone Marrow Disorders
  • Myeloproliferative Neoplasms

How does my health care provider use a Reticulocyte Count test?

A reticulocyte test is used to assess the number and/or percentage of reticulocytes in the blood to aid in the diagnosis of red blood cell abnormalities such as anemia and bone marrow illnesses. Reticulocytes are young red blood cells that have just been created. Before being released into the circulation, they develop and mature in the bone marrow.

The reticulocyte test can be used in the following situations:

  • To help determine the reason of aberrant results on a complete blood count, RBC count, hemoglobin, or hematocrit.
  • To see if the bone marrow is appropriately functioning and reacting to the body's need for red blood cells.
  • To aid in the detection and differentiation of various kinds of anemia
  • To track how well people are responding to treatments, such as those for iron deficiency anemia.
  • To track the activity of the bone marrow after therapies like chemotherapy.
  • To keep track of how well you're doing after a bone marrow transplant.

A reticulocyte count is usually done using an automated device and can be done in conjunction with a complete blood count, which includes an RBC count, hemoglobin, and hematocrit. It is possible to report either an absolute number of reticulocytes or a percentage of reticulocytes. The number of reticulocytes is compared to the total number of red blood cells as a percentage:

[ Number of Reticulocytes / Total Red Blood Cells ] X 100 = Reticulocyte Percentage

Several more tests, in addition to a reticulocyte count, can be done to further screen someone for a disorder that affects RBC production. Here are a few examples:

  • Iron testing
  • Haptoglobin
  • G6PD
  • Erythropoietin
  • Vitamin B12 and Folate

Following up on abnormal results from early tests, a bone marrow aspiration and biopsy may be performed. This is an invasive operation that is not performed on everyone. If necessary, it can, however, supply extra information.

What do my reticulocyte count test results mean?

The results must be carefully evaluated in conjunction with the results of other tests, such as a red blood cell count, hemoglobin, hematocrit, or a complete blood count. The reticulocyte count, in general, reflects recent bone marrow activity. The results could reveal whether a disease or condition is present that is causing an elevated need for new RBCs, as well as whether the bone marrow is capable of meeting that demand. Overproduction of RBCs may be detected in some cases.

When anemia is present and the bone marrow responds adequately to the demand for more RBCs, the bone marrow will create more and allow for the early release of more immature RBCs, resulting in an increase in the number of reticulocytes in the blood.

A high reticulocyte count along with low RBCs, hemoglobin, and hematocrit may indicate the following conditions:

  • When a person bleeds, the number of reticulocytes increases after a few days to make up for the loss of red blood cells. If someone has chronic blood loss, the marrow will try to keep up with the need for new RBCs by increasing the number of reticulocytes.
  • Anemia is caused by an increase in the breakdown of RBCs in hemolytic anemia. To compensate, the bone marrow boosts RBC production, resulting in a high reticulocyte count.
  • Hemolytic illness of the newborn: Similar to hemolytic anemia, this syndrome causes an increase in RBC destruction.

For example, a low reticulocyte count with low hemoglobin, low red blood cells, and low hematocrit can be detected when:

  • Anemia due to a lack of iron
  • Folic acid deficiency or pernicious anemia
  • Aplastic anemia is a kind of anemia that occurs when the
  • Radiation therapy is a type of treatment that uses a
  • Infection or malignancy can induce bone marrow failure.
  • A low level of erythropoietin can be caused by severe kidney disease.
  • Alcoholism

When a person has anemia, the percentage of reticulocytes in their blood may appear to be higher than the total number of RBCs. A calculation known as a corrected reticulocyte count or reticulocyte index may be reported to get a more accurate estimate of bone marrow function. When a person's hematocrit is compared to a normal hematocrit reading, the RI is computed. The reticulocyte production index and an immature reticulocyte fraction are two more estimates that may be presented. The IRF was once known as the reticulocyte maturity index, but it is currently the most widely used phrase to describe the younger percentage of reticulocytes.

The existence of a disease or condition is indicated by the reticulocyte test, however it is not specifically diagnostic of any disease. It's a warning that more research is needed, as well as a method for monitoring therapy effectiveness.

When reticulocyte numbers increase after chemotherapy, a bone marrow transplant, or treatment for an iron, vitamin B12, or folate shortage, bone marrow RBC production is on the mend.

A high reticulocyte count can indicate an overproduction of RBCs in people who do not have anemia or have a high RBC count. This can be caused by a variety of factors, including:

  • Polycythemia vera
  • Excess erythropoietin-producing tumor

Pernicious Anemia is a type of anemia in which the intestines cannot effectively absorb vitamin B12, which results in a reduced count of red blood cells. In general, anemia is a condition that involves a lack of red blood cells, which are essential for transporting oxygen to the tissues of the body. There are various types of anemia, but pernicious anemia is a type of vitamin B12 anemia that is typically caused by an autoimmune problem. Here, we’ll discuss this rare condition, how it’s diagnosed, and how it can be treated. 

About Pernicious Anemia

When a person is diagnosed with pernicious anemia, their body cannot make enough red blood cells because it doesn’t have the necessary vitamin B12 to make them. Vitamin B12 is found in many foods, but people with this condition aren’t able to properly absorb this nutrient from food. The result is that they can’t make enough healthy red blood cells to serve their body’s needs. 

Our red blood cells require vitamin B12 for normal cell division. A lack of the nutrient causes red blood cells to be too large. Cells that are too large may fail to get out of the bone marrow where they’re produced. A reduced count of red blood cells means that there are fewer cells able to carry oxygen to the body’s essential organs like the brain and heart as well as other organs and tissues. 

What Causes Pernicious Anemia?

Pernicious anemia occurs because the body cannot absorb vitamin B12 from foods to adequately produce red blood cells. This is a rare problem, but an autoimmune response often causes it. Typically, pernicious anemia occurs because the protein in the stomach known as ‘intrinsic factor’ is diminished because the body’s own immune system mistakenly attacks it or the processes that produce it. Intrinsic factor is needed to help the body absorb vitamin B12. Without enough of this protein, the body, ultimately, can’t make an adequate supply of red blood cells.

Some cases of pernicious anemia involve an inherited disorder. Sometimes children are born with a disorder that prevents the body from making intrinsic factor. This condition is called congenital pernicious anemia. 

Other cases may relate to diet; for instance, a person can suffer from pernicious anemia if they don’t get enough vitamin B12 in their diet. A person’s ability to absorb vitamin B12 can also be compromised if another health condition is present such as celiac disease, Crohn’s disease, or HIV. Some medications can lead to vitamin B12 malabsorption in the small intestine. A tapeworm infection can also cause pernicious anemia. In some cases, gastric bypass procedures can also lead to this condition. 

Are There Risk Factors for Pernicious Anemia?

Medical researchers have found that there are certain risk factors that may make a person more susceptible to the development of this condition. These risk factors include: 

  • Northern European / Scandinavian descent
  • Family history of pernicious anemia
  • Having type 1 diabetes
  • Diagnosed with celiac disease or Crohn’s disease
  • Aged 60 or over

What Are the Signs and Symptoms of Pernicious Anemia?

Many of the signs and symptoms of pernicious anemia occur with all forms of anemia. Others are specifically related to the lack of vitamin B12 that occurs with this disorder. People who suffer from pernicious anemia may experience extreme fatigue, which is common to all forms of anemia. People feel tired because the body doesn’t have an adequate supply of red blood cells needed to carry oxygen to its organs and tissues. 

Other signs and symptoms of pernicious anemia include:

  • Headache
  • Dizziness
  • Chest pain
  • Pale skin
  • Cold hands and feet

While these symptoms can occur with any form of anemia, pernicious anemia also features symptoms that are particularly associated with a lack of vitamin B12. Symptoms of vitamin B12 deficiency include:

  • Hands and feet numbness
  • Muscle weakness
  • Loss of reflexes
  • Problems with balance
  • Confusion
  • Nausea
  • Bloating
  • Heartburn
  • Loss of appetite
  • Smooth and thick red tongue

Pernicious anemia can cause complications such as heart murmurs and even heart failure. Untreated pernicious anemia can be deadly. Fortunately, treatment can alleviate these symptoms, and people can usually recover to lead a normal life. 

How Is Pernicious Anemia Diagnosed?

Test results can support a diagnosis of pernicious anemia; however, many doctors may suspect the condition based on the symptoms present in the individual and a physical exam. Tests are necessary because the physician will need to know if the disorder is caused by a lack of intrinsic factor or something else. Doctors also need to learn how severe the condition is in order to provide the best possible treatment. Ulta Lab Tests can support a diagnosis of pernicious anemia. Its tests are reliable and easy to use.

What Are the Diagnostic Tests Available to Diagnose Pernicious Anemia?

Healthcare provides rely on blood tests to make a diagnosis of pernicious anemia as well as to understand what may be causing it. Each test can pinpoint some factor related to pernicious anemia, such as the presence of certain antibodies or abnormal blood cell counts. High levels of some elements like homocysteine can lead to a diagnosis of this condition. Some of the tests used most frequently to diagnose this disease are:

Complete Blood Count Panel

A complete blood count (CBC) tests various parts of the blood, such as hemoglobin and hematocrit. A low level of either of these elements may be indicative of anemia. Hemoglobin is a protein that’s rich in iron and helps the red blood cells deliver oxygen to parts all over the body. Hematocrit measures how much space in the blood is taken up by red blood cells. 

A CBC test provides a count of red blood cells, white blood cells, and platelets in the blood. If these counts are not in the normal range, a problem like pernicious anemia is likely present. Sometimes abnormal results can indicate a different problem, such as an infection. 

Finally, a CBC provides a measurement of red blood cell size. A telltale feature of pernicious anemia is red blood cells that are larger than normal. 

Other Tests to Diagnose Pernicious Anemia

If the CBC reveals the presence of pernicious anemia, more tests will be ordered to determine what is causing the disorder to occur. For instance, if a test uncovers intrinsic factor antibodies, the pernicious anemia is caused by an autoimmune response. Bone marrow tests may also be ordered to test the size of the marrow cells, which are typically larger in cases involving pernicious anemia.

Here is an overview of various tests used to diagnose pernicious anemia:

Note the following tests that rule out iron deficiency anemia:

  • Iron Total: iron and iron-binding capacity tests will indicate if pernicious anemia is present.
  • TIBC: this test measures iron binding capacity; a poor measure can indicate pernicious anemia. 
  • Ferritin: Pernicious anemia can cause low ferritin levels; if ferritin is tested low, the condition may be diagnosed.
  • Transferrin: this protein will be found in the blood if iron is low; low iron can indicate pernicious anemia.

How Is Pernicious Anemia Treated?

People who are diagnosed with pernicious anemia may require lifelong treatment that includes vitamin B12 injections. Treatment should prevent the anemia as well as its symptoms. If the cause of the pernicious anemia can be found, it may also be treated--if possible. Healthcare providers will also need to manage any complications that occur, such as heart or nerve damage. 

If you are diagnosed with pernicious anemia, your doctor may recommend either vitamin B12 pills or vitamin B12 injections. If your condition is severe, injections are usually prescribed first. Healthcare providers will inject vitamin B12 weekly or even daily in order to achieve the optimum amount of this vitamin in the bloodstream.

Once the vitamin B12 has reached a normal level, injections may only be required on a monthly basis. In cases that are less severe, patients may be prescribed pills or even a nose spray containing vitamin B12. Most people will experience symptom alleviation after a mere few days of treatment. Over the course of treatment, healthcare providers may adjust the dosing of vitamin B12 depending on the patient’s needs. 

Sometimes other treatments are needed to address other root causes of the pernicious anemia or to treat other conditions that the patient is experiencing, such as celiac disease. In many cases, patients may be able to administer their own injections of vitamin B12. Depending on the patient’s condition, they may receive these shots at home from a caregiver or may wish to travel to their health clinic to receive the injections. 

What about Pernicious Anemia Complications?

Health complications can occur as a result of untreated pernicious anemia. These might include heart irregularities or even heart failure. On the other hand, even with treatment, a person may experience health complications related to their anemia. For instance, gastric cancer is a dangerous complication that can occur with this condition. Doctors will monitor patients for signs of this condition. 

Other complications may include gastrointestinal problems, neurological problems (i.e. memory loss), and peripheral nerve damage. 

Living with Pernicious Anemia

People with pernicious anemia often live normal lives with treatment; however, they may require lifelong treatment and will need routine monitoring to ensure that no complications are arising and that the optimum dose of vitamin B12 is being provided. If you or a loved one is diagnosed with this condition, it’s important to meet with your physician on a regular basis to ensure that it’s managed effectively.
