Description: An ionized calcium test is a blood test that is used to screen for, diagnose, and monitor a wide range of medical conditions.

Also Known As: Ionized Ca Test, Serum Ionized Calcium Test, Calcium Blood Test, Calcium Ionized Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is an Ionized Calcium test ordered?

A blood calcium test is frequently requested during a general medical evaluation. It's usually part of the comprehensive metabolic panel or the basic metabolic panel, two sets of tests that can be done during an initial evaluation or as part of a routine medical checks.

Many people do not experience symptoms of high or low calcium until their levels are dangerously high or low.

When someone develops numbness around the mouth, hands, and feet, as well as muscle spasms in those areas, an ionized calcium test may be ordered. Low ionized calcium levels can cause these symptoms. When calcium levels fall slowly, however, many people have no symptoms.

What does an Ionized Calcium blood test check for?

Calcium is one of the most plentiful and vital minerals in the human body. It is required for cell signaling as well as the proper operation of muscles, nerves, and the heart. Calcium is essential for blood clotting as well as bone growth, density, and maintenance. This test determines how much calcium is present in the blood.

Calcium is found complexed in the bones for 99 percent of the time, while the remaining 1% circulates in the blood. Calcium levels are closely monitored; if too little is absorbed or consumed, or if too much is lost through the kidney or stomach, calcium is removed from bone to keep blood concentrations stable. Approximately half of the calcium in the blood is metabolically active and "free." The other half is "bound" to albumin, with a minor proportion complexed to anions like phosphate, and both of these forms are metabolically inactive.

Blood calcium can be measured using two different tests. The free and bound forms of calcium are measured in the total calcium test. Only the free, physiologically active form of calcium is measured in the ionized calcium test.

Lab tests often ordered with an Ionized Calcium test:

  • Phosphorus
  • Vitamin D
  • Magnesium
  • PTH
  • Magnesium
  • Albumin
  • Basic Metabolic Panel (BMP)
  • Comprehensive Metabolic Panel (CMP)

Conditions where an Ionized Calcium test is recommended:

  • Kidney Disease
  • Thyroid Disease
  • Alcoholism
  • Malnutrition
  • Parathyroid Diseases
  • Breast Cancer
  • Multiple Myeloma

How does my health care provider use an Ionized Calcium test?

A blood calcium test is used to screen for, diagnose, and monitor a variety of bone, heart, nerve, kidney, and tooth disorders. If a person has signs of a parathyroid disease, malabsorption, or an overactive thyroid, the test may be ordered.

A total calcium level is frequently checked as part of a standard health check. It's part of the comprehensive metabolic panel and the basic metabolic panel, which are both collections of tests used to diagnose or monitor a range of ailments.

When a total calcium result is abnormal, it is interpreted as a sign of an underlying disease. Additional tests to assess ionized calcium, urine calcium, phosphorus, magnesium, vitamin D, parathyroid hormone, and PTH-related peptide are frequently performed to assist determine the underlying problem. PTH and vitamin D are in charge of keeping calcium levels in the blood within a narrow range of values.

Measuring calcium and PTH combined can assist identify whether the parathyroid glands are functioning normally if the calcium is abnormal. Testing for vitamin D, phosphorus, and/or magnesium can assist evaluate whether the kidneys are excreting the right amount of calcium, and measuring urine calcium can help detect whether additional deficits or excesses exist. The balance of these many compounds is frequently just as critical as their concentrations.

The total calcium test is the most common test used to determine calcium status. Because the balance between free and bound calcium is usually constant and predictable, it is a reliable reflection of the quantity of free calcium present in the blood in most cases. However, the balance between bound and free calcium is altered in some persons, and total calcium is not a good indicator of calcium status. Ionized calcium measurement may be required in certain cases. Critically sick patients, those receiving blood transfusions or intravenous fluids, patients undergoing major surgery, and persons with blood protein disorders such low albumin are all candidates for ionized calcium testing.

What do my Ionized Calcium test results mean?

The amount of calcium circulating in the blood is not the same as the amount of calcium in the bones.

A feedback loop including PTH and vitamin D regulates and stabilizes calcium uptake, utilization, and excretion. Conditions and disorders that disturb calcium control can induce abnormal acute or chronic calcium elevations or declines, resulting in hypercalcemia or hypocalcemia symptoms.

Total calcium is usually tested instead of ionized calcium since it is easier to do and requires no additional treatment of the blood sample. Because the free and bound forms of calcium make up about half of the total, total calcium is usually a decent depiction of free calcium. Because nearly half of the calcium in blood is bonded to protein, high or low protein levels might alter total calcium test findings. In these circumstances, an ionized calcium test is more appropriate for measuring free calcium.

A normal total or ionized calcium test, when combined with other normal laboratory findings, indicates that a person's calcium metabolism is normal and blood levels are properly managed.

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

Description: Ceruloplasmin is a blood test that measures that amount of Ceruloplasmin in the blood’s serum. Ceruloplasmin, or Copper Oxide, is a protein that is created in the liver and is used to transport copper from the liver to the parts of the body that need it, including the blood.

Also Known As: Copper Oxide Test, Wilson’s Disease Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Ceruloplasmin test ordered?

When somebody has symptoms that a health practitioner suspects are due to Wilson disease, a ceruloplasmin test may be ordered alone or in combination with blood and 24-hour urine copper testing.

What does a Ceruloplasmin blood test check for?

Ceruloplasmin is a copper-containing enzyme that aids in iron metabolism in the body. The level of ceruloplasmin in the blood is measured with this test.

Copper is a vital mineral that regulates iron metabolism, connective tissue creation, cellular energy production, and nervous system function. The intestines absorb it from meals and liquids, and it is subsequently transferred to the liver, where it is stored or used to make a variety of enzymes.

To make ceruloplasmin, the liver binds copper to a protein and then releases it into the bloodstream. Ceruloplasmin binds about 95 percent of the copper in the blood. As a result, the ceruloplasmin test can be performed in conjunction with one or more copper tests to assist diagnose Wilson disease, a genetic illness in which the liver, brain, and other organs store too much copper.

Lab tests often ordered with a Ceruloplasmin test:

  • Copper

Conditions where a Ceruloplasmin test is recommended:

  • Wilson’s Disease
  • Liver Diseases

How does my health care provider use a Ceruloplasmin test?

Wilson disease is a rare genetic ailment characterized by excessive copper accumulation in the liver, brain, and other organs, as well as low levels of ceruloplasmin. Ceruloplasmin testing is performed in conjunction with blood and/or urine copper assays to assist diagnosis Wilson disease.

Copper is a mineral that plays an important role in the human body. Ceruloplasmin binds about 95 percent of the copper in the blood. In an unbound state, just a minimal quantity of copper is present in the blood.

A ceruloplasmin test may be ordered in conjunction with a copper test to assist diagnose problems in copper metabolism, copper deficiency, or Menkes kinky hair syndrome, a rare genetic condition.

What do my Ceruloplasmin test results mean?

Ceruloplasmin levels are frequently tested in conjunction with copper testing because they are not indicative of a specific illness.

Wilson disease can be identified by low ceruloplasmin and blood copper levels, as well as high copper levels in the urine.

About 5% of persons with Wilson disease who have neurological symptoms, as well as up to 40% of those with hepatic symptoms, especially if they are critically unwell, will have normal ceruloplasmin levels.

The person tested may have a copper deficiency if ceruloplasmin, urine, and/or blood copper values are low.

Anything that affects the body's ability to metabolize copper or the supply of copper has the potential to impact blood ceruloplasmin and copper levels.

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. 

Lab tests often ordered with a Complete Blood Count test: 

  • Reticulocytes
  • Iron and Total Iron Binding Capacity
  • Basic Metabolic Panel
  • Comprehensive Metabolic Panel
  • Lipid Panel
  • Vitamin B12 and Folate
  • Prothrombin with INR and Partial Thromboplastin Times
  • Sed Rate (ESR)
  • C-Reactive Protein
  • Epstein-Barr Virus
  • Von Willebrand Factor Antigen

  • Anemia
  • Aplastic Anemia
  • Iron Deficiency Anemia
  • Vitamin B12 and Folate Deficiency
  • Sickle Cell Anemia
  • Heart Disease
  • Thalassemia
  • Leukemia

  • Mononucleosis

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.

Description: Copper is a blood test that measures the amount of copper in the blood's plasma. Copper levels in the blood can help to diagnose Wilson's Disease.

Also Known As: Cu Test, Blood Copper Test, Free Copper Test, Hepatic Copper Test, Copper Serum Test, Copper Plasma Test, Copper Blood Test

Collection Method: Blood Draw

Specimen Type: Plasma or Serum

Test Preparation: No preparation required

When is a Copper test ordered?

When a health practitioner suspects Wilson disease, excess copper storage, or copper poisoning, one or more copper tests are requested along with ceruloplasmin.

When copper and ceruloplasmin results are abnormal or inconclusive, a hepatic copper test may be conducted to further evaluate copper storage.

What does a Copper blood test check for?

Copper is an important mineral that the body uses to make enzymes. These enzymes are involved in the regulation of iron metabolism, the development of connective tissue, cellular energy production, the production of melanin, and nervous system function. This test determines how much copper is present in the blood, urine, or liver.

Nuts, chocolate, mushrooms, seafood, whole grains, dried fruits, and liver are all high in copper. Copper may be absorbed into drinking water as it passes through copper pipes, and copper may be absorbed into food as it is cooked or served on copper dishes. Copper is absorbed from food or liquids in the intestines, converted to a non-toxic form by binding it to a protein, and transported to the liver in normal circumstances. To make the enzyme ceruloplasmin, the liver saves some copper and binds the remainder to another protein called apoceruloplasmin. Ceruloplasmin binds about 95 percent of the copper in the blood, with the rest attached to other proteins like albumin. In a free condition, only a little amount is present in the blood. Excess copper is excreted by the liver in the bile, which is then excreted by the body in the feces. Copper is also excreted in the urine in small amounts.

Copper excess and deficiency are uncommon. Wilson disease is a rare genetic ailment that causes the liver, brain, and other organs to store too much copper. Excess copper can arise when a person is exposed to and absorbs high amounts of copper in a short period of time or little amounts over a long period of time.

Copper deficiency can arise in patients with severe malabsorption diseases such cystic fibrosis and celiac disease, as well as infants who are exclusively fed cow-milk formulas.

Menkes kinky hair syndrome is a rare X-linked hereditary disorder that causes copper shortage in the brain and liver of affected babies. Seizures, delayed development, aberrant artery growth in the brain, and unique gray brittle kinky hair are all symptoms of the condition, which mostly affects men.

Lab tests often ordered with a Copper test:

  • Ceruloplasmin
  • Heavy Metals
  • ACTH
  • Aldosterone
  • 17-Hydroprogesterone
  • Growth Hormone

Conditions where a Copper test is recommended:

  • Wilson Disease
  • Malnutrition

How does my health care provider use a Copper test?

Copper testing is largely used to detect Wilson disease, a rare genetic ailment in which the liver, brain, and other organs accumulate an excessive amount of copper. A copper test is less usually used to detect copper excess caused by another ailment, to diagnose a copper deficit, or to track treatment for one of these conditions.

Copper is a necessary mineral, but too much of it can be harmful. The majority of it is bound to the enzyme ceruloplasmin in the blood, leaving only a little quantity "free" or unbound.

A whole blood copper test is usually ordered in conjunction with a ceruloplasmin level. If the findings of these tests are abnormal or ambiguous, a 24-hour urine copper test to monitor copper elimination and/or a copper test on a liver biopsy to check copper storage in the liver may be conducted.

A free blood copper test is sometimes ordered as well. If Wilson disease is suspected, genetic testing for mutations in the ATP7B gene may be undertaken. However, these tests are only available in a restricted number of locations and are usually carried out in specialized reference or research laboratories.

A copper test may be used to identify Menkes kinky hair syndrome, a rare inherited copper transport failure condition.

What do my Copper test results mean?

Copper test findings are frequently linked to ceruloplasmin levels and considered in context. Copper results that are abnormal are not indicative of a specific illness; rather, they signal that more research is needed. Because ceruloplasmin is an acute phase reactant, it might be raised if inflammation or severe infections are present, making interpretation difficult. Ceruloplasmin and copper levels rise during pregnancy, as well as with the use of estrogen and oral contraceptives.

Wilson disease is characterized by low blood copper concentrations, elevated urine copper levels, low ceruloplasmin levels, and increased liver copper.

Elevated copper concentrations in the blood and urine, as well as normal or increased ceruloplasmin levels, may suggest excessive copper exposure or be linked to disorders that reduce copper excretion, such as chronic liver disease, or release copper from tissues, such as acute hepatitis. Chronic diseases can cause an increase in hepatic copper levels.

Copper deficiency is indicated by lower copper concentrations in the blood and urine, as well as lower ceruloplasmin levels.

A normal hepatic copper test could mean that copper metabolism is normal, or that the distribution of copper in the liver is uneven, and that the sample isn't reflective of the person's health.

If a person is being treated for Wilson disease or copper toxicity with copper-binding medicines, their 24-hour urine copper levels may be high until their body copper stores are depleted. Copper concentrations in the blood and urine should return to normal over time.

If a person is being treated for a copper deficient disorder and their ceruloplasmin and total copper levels start to rise, the condition is likely responding to the treatment.

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.

Description: A Hemoglobin (Hgb) test is a blood test that measures the amount of hemoglobin your red blood cells contain.

Also Known As: Hb Test, Hgb Test

Collection Method: Blood Draw

Specimen Type: Whole Blood

Test Preparation: No preparation required

When is a Hemoglobin test ordered?

The hemoglobin test may be requested as part of a general health assessment or when a person exhibits signs and symptoms of a red blood cell disorder such as anemia or polycythemia.

When someone has been diagnosed with recurrent bleeding difficulties, chronic anemias, or polycythemia, this test may be done numerous times or on a regular basis to check the effectiveness of treatment. It's also possible that it'll be ordered on a regular basis for those having therapy for cancers that are known to harm the bone marrow.

What does a Hemoglobin blood test check for?

Hemoglobin is an iron-containing protein found in all red blood cells, which gives them their distinctive red color. RBCs use hemoglobin to bind to oxygen in the lungs and transport it to tissues and organs all over the body. It also aids in the movement of a little amount of carbon dioxide, which is a byproduct of cell metabolism, from tissues and organs to the lungs, where it is exhaled.

The hemoglobin test determines how much hemoglobin is present in a person's blood sample. To swiftly assess an individual's red blood cells, a hemoglobin level can be used alone or in conjunction with a hematocrit, a test that assesses the fraction of blood made up of RBCs. Red blood cells, which account for roughly 40% of the amount of blood, are created in the bone marrow and released into the bloodstream when they are mature, or nearly so. RBCs have a 120-day lifespan, and the bone marrow must constantly manufacture new RBCs to replace those that have aged and degraded or have been lost due to hemorrhage.

RBCs, and thus the level of hemoglobin in the blood, can be affected by a variety of diseases and situations. When the quantity of red blood cells grows, the hemoglobin level and hematocrit both rise. When the synthesis of RBCs by the bone marrow decreases, RBC destruction increases, or blood is lost owing to hemorrhage, the hemoglobin level and hematocrit fall below normal. Anemia is a disorder in which the body's tissues and organs do not acquire enough oxygen, causing exhaustion and weakness. It is caused by a decline in RBC count, hemoglobin, and hematocrit. Polycythemia occurs when the body produces too many RBCs, causing the blood to thicken, resulting in sluggish blood flow and other complications.

Lab tests often ordered with a Hemoglobin test:

  • Complete Blood Count (CBC)
  • Hematocrit
  • Red Blood Cell Count (RBC Count)
  • Blood Smear
  • Iron Total
  • Ferritin
  • Reticulocyte Count
  • Vitamin B12
  • Folate
  • Red Cell Indices
  • G6PD
  • Erythropoietin
  • Hemoglobinopathy Evaluation

Conditions where a Hemoglobin test is recommended:

  • Anemia
  • Sickle Cell Anemia
  • Thalassemia
  • Myeloproliferative Neoplasms
  • Hemoglobin Abnormalities
  • Bone Marrow Disorders

How does my health care provider use a Hemoglobin test?

Anemia is commonly detected with a hemoglobin test in conjunction with a hematocrit or as part of a complete blood count. The test can be used to detect, diagnose, or track a variety of illnesses and disorders that impact red blood cells and/or hemoglobin levels in the blood. All red blood cells include hemoglobin, an iron-containing protein that allows RBCs to bind to oxygen in the lungs and transport it to tissues and organs throughout the body.

A hemoglobin test can be used for a variety of purposes, including:

  • Anemia and polycythemia are diagnosed, diagnosed, and measured.
  • Assess the patient's reaction to anemia or polycythemia treatment.
  • If the anemia is severe, you can help make decisions about blood transfusions or other therapies.

Some factors influence RBC production in the bone marrow, resulting in an increase or decrease in the quantity of mature RBCs discharged into the bloodstream. The longevity of RBCs in the circulation can be influenced by a variety of factors. The overall amount of RBCs and hemoglobin will diminish if there is greater destruction of RBCs or loss of RBCs through bleeding, and/or the bone marrow is unable to make new ones quickly enough, leading in anemia.

This test can tell you if you have an issue with red blood cell production or longevity, but it can't tell you what's causing it. A blood smear, reticulocyte count, iron studies, vitamin B12 and folate levels, and, in more severe cases, a bone marrow examination are some of the other tests that may be conducted at the same time or as follow-up to establish a reason.

What do my Hemoglobin test results mean?

Because hemoglobin levels are frequently measured as part of a complete blood count, the results of other components are taken into account. Hemoglobin levels must be interpreted in conjunction with other indicators such as RBC count, hematocrit, reticulocyte count, and/or red blood cell indices when they rise or fall. Other characteristics to consider are age, gender, and race. Hemoglobin reflects the RBC count and hematocrit results in general.

Anemia is defined as a low hemoglobin level combined with a low RBC count and a low hematocrit. Among the causes are:

  • Excessive blood loss-as a result of severe trauma or continuous bleeding from the digestive tract, bladder, or uterus.
  • Iron, folate, or B12 deficiency are examples of nutritional inadequacies.
  • Toxins, radiation, chemotherapy, infection, and medicines can all cause damage to the bone marrow.
  • Myelodysplastic syndrome, aplastic anemia, or tumors of the bone marrow, such as lymphoma, leukemia, multiple myeloma, or other cancers of the bone marrow
  • Renal failure—severe and chronic kidney illnesses cause the kidneys to produce less erythropoietin, a hormone that drives RBC synthesis in the bone marrow.
  • Inflammatory diseases or disorders that last a long time
  • Hemoglobin production is reduced.
  • Excessive destruction of red blood cells, such as hemolytic anemia caused by autoimmunity or faults in the red blood cell itself, such as hemoglobinopathy, RBC membrane abnormalities, or RBC enzyme.

Polycythemia is defined as a high hemoglobin level combined with a high RBC count and hematocrit. Among the causes are:

  • Lung disease-when a person's body is unable to breathe in and absorb enough oxygen. As a result, the body produces more red blood cells to compensate.
  • Congenital heart disease—in some cases, an improper connection between the two sides of the heart occurs, resulting in lower blood oxygen levels. The body responds by creating extra red blood cells in an attempt to compensate.
  • Excess erythropoietin-producing kidney tumors
  • Hemoglobin levels in heavy smokers are higher than in nonsmokers.
  • Genetic factors
  • Having to live at a high altitude
  • Dehydration causes hemoglobin to rise unnaturally when the volume of liquid in the blood declines.
  • Polycythemia vera-a rare condition in which the body creates too many RBCs.

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 Magnesium test is a blood test that measures magnesium levels in your blood’s serum and is useful in determining the cause of abnormal levels of magnesium, calcium, and or potassium, and is useful in the evaluation of a wide variety of disorders such as diabetes, kidney disease, and malabsorption.

Also Known As: Magnesium RBC Test, Magnesium Red Bood Cell Test, Mg Test, Mag test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Magnesium RBC test ordered?

Magnesium tests may be requested by health professionals as a follow-up to chronically low calcium and potassium levels in the blood. It may also be prescribed if a person exhibits symptoms of a magnesium deficiency, such as twitching, muscle weakness, cramping, disorientation, seizures, or cardiac arrhythmias.

As part of an evaluation of malabsorption, malnutrition, diarrhea, or alcoholism, a health practitioner may prescribe a magnesium level to check for a deficit. Testing may also be done if someone is taking drugs that cause the kidneys to excrete magnesium. When magnesium and/or calcium supplementation is required, the level of magnesium in the blood can be measured at regular intervals to ensure that the medication is working.

A magnesium test, along with kidney function tests such as a BUN and creatinine, may be given on a regular basis when someone has a kidney problem or uncontrolled diabetes to help monitor renal function and ensure that the person is not excreting or retaining excessive quantities of magnesium.

What does a Magnesium RBC test check for?

The magnesium test measures the amount of magnesium in your blood’s serum. Magnesium is a mineral that supports healthy bones, muscle contraction, neuron function, and energy production. It enters the body through the diet and is then absorbed by the small intestine and colon. Bones, cells, and tissues all contain the element magnesium. It is challenging to determine the total magnesium content from blood tests alone since only 1% of the magnesium present in the body is accessible in the blood. However, this test is still useful for figuring out a person's magnesium levels.

Small levels of magnesium can be found in a range of meals, including green vegetables like spinach, whole grains, and nuts. Magnesium is commonly found in foods that contain dietary fiber. The body regulates how much magnesium it receives and excretes or conserves in the kidneys to keep its magnesium level stable.

Magnesium deficiency can occur as a result of malnutrition, malabsorption-related disorders, or excessive magnesium loss via the kidneys. Magnesium overload can occur as a result of taking magnesium-containing antacids or a decrease in the kidneys' ability to eliminate magnesium.

There may be no or few nonspecific symptoms in someone with mild to severe magnesium insufficiency. Nausea, loss of appetite, exhaustion, confusion, muscle cramps, seizures, changes in heart rate, and numbness or tingling are all symptoms of persistent or severe deficits. They can also wreak havoc on calcium metabolism and worsen calcium deficiency. Nausea, muscle weakness, loss of appetite, and an erratic heart rate are some of the symptoms of excess magnesium, which are similar to those of deficiency.

Lab tests often ordered with a Magnesium RBC test:

  • Complete Blood Count
  • Calcium
  • Iron Total and Total Iron binding capacity
  • Potassium
  • Comprehensive Metabolic Panel
  • Lipid Panel
  • Phosphorus
  • Parathyroid Hormone
  • Vitamin D
  • Glucose

Conditions where a Magnesium RBC test is recommended:

  • Kidney Disease
  • Hypothyroidism
  • Diabetes
  • Alcoholism
  • Malnutrition
  • Malabsorption
  • Diarrhea
  • Dehydration
  • Parathyroid Diseases
  • Addison Disease
  • Adrenal Insufficiency

How does my health care provider use a Magnesium RBC test?

Magnesium levels in the blood are measured with a magnesium test. Atypical magnesium levels are most frequently found in conditions or illnesses that result in insufficient or excessive renal excretion of magnesium or impaired intestinal absorption of magnesium. Magnesium levels can be measured to determine the severity of kidney issues, uncontrolled diabetes, and/or uncontrolled diabetes as well as to diagnose gastrointestinal diseases.

Because a low magnesium blood level can lead to chronically low calcium and potassium levels over time, it may be tested to help diagnose calcium, phosphorus, potassium, and/or parathyroid hormone – another component of calcium regulation – problems.

Magnesium levels can be checked on a regular basis to monitor the response to oral or intravenous magnesium supplements, and calcium supplementation can be monitored using calcium and phosphorus tests.

What does my Magnesium RBC test result mean?

Low magnesium levels in the blood can suggest that a person isn't getting enough magnesium or is excreting too much. Deficiencies are most commonly encountered in:

  • Low nutritional intake 
  • Gastrointestinal conditions
  • Diabetes that is uncontrolled
  • Hypoparathyroidism
  • Use of a diuretic for a long time
  • diarrhea that lasts for a long time
  • Following surgery
  • Burns that are severe
  • Pregnancy toxicity

Magnesium levels in the blood are rarely elevated as a result of food sources, but rather as a result of an excretion problem or excessive supplementation. Increased levels can be cause by:

  • Failure of the kidneys
  • Hyperparathyroidism
  • Hypothyroidism
  • Dehydration
  • Diabetic acidosis
  • Addison's disese
  • Use of antacids or laxatives containing magnesium

Description: A Potassium RBC test is a test that is normally part of an electrolyte panel or Comprehensive Metabolic panel to help diagnose and monitor any electrolyte imbalances.

Also Known As:  K Test

Collection Method: Blood Draw

Specimen Type: Whole Blood

Test Preparation: No preparation required

When is a Potassium RBC test ordered?

When patients get a normal medical exam or are being assessed for a serious illness, potassium levels may be required.

When a healthcare provider is diagnosing and monitoring hypertension, diabetic ketoacidosis, and renal disease, as well as monitoring a patient on dialysis, diuretic medication, or intravenous fluids, potassium tests may be performed at regular intervals.

What does a Potassium RBC test check for?

Potassium is a necessary electrolyte for cell metabolism. It assists in the delivery of nutrients into cells and the removal of waste materials from cells. It also plays a role in muscle function by assisting in the transmission of messages between neurons and muscles. This test determines how much potassium is present in the blood and/or urine.

Potassium, along with other electrolytes like sodium, chloride, and bicarbonate, aids in fluid regulation and maintains a stable acid-base balance in the body. Potassium is found in all body fluids, although it is concentrated in the cells. Only a trace amount is found in fluids outside of cells and in the blood's liquid portion.

The majority of the potassium we require comes from the foods we eat, and most people consume enough potassium. The body consumes what it needs and excretes the rest through the urine. The body works to keep the potassium level in the blood within a restricted range. Aldosterone, a hormone generated by the kidney's adrenal glands, is the key regulator.

Because potassium levels in the blood are so low, even little adjustments can have a big impact. There might be major health effects if potassium levels are either low or too high; a person may get shock, respiratory failure, or heart rhythm abnormalities. An abnormal potassium level can affect neuron and muscle function; for example, the heart muscle's capacity to contract may be impaired.

Lab tests often ordered with Potassium RBC:

  • Chloride
  • Sodium
  • Bicarbonate
  • Electrolytes
  • Basic Metabolic Panel (BMP)
  • Comprehensive Metabolic Panel (CMP)
  • Aldosterone
  • Renin

Conditions where a Potassium RBC test is recommended:

  • Hypertension
  • Acidosis
  • Alkalosis
  • Kidney Disease
  • Heart Disease
  • Conn Syndrome
  • Addison Disease

How does my health care provider use a Potassium RBC test?

A potassium test is used to detect irregular potassium values, such as high and low potassium. It's frequently utilized as part of a standard physical's electrolyte panel or basic metabolic panel.

Potassium is a necessary electrolyte for cell metabolism. It assists in the delivery of nutrients into cells and the removal of waste materials from cells. It also has a role in muscular function, assisting in the transmission of messages between nerves and muscles, as well as heart function.

The potassium test can be used to detect and/or monitor kidney disease, which is the most prevalent cause of elevated potassium levels in the blood. When someone has diarrhea and vomiting, excessive sweating, or a range of symptoms, it can also be utilized to check for abnormal levels. Many disorders can cause elevated potassium levels in the blood. If metabolic acidosis is suspected, or if high blood pressure or other indications of disease are present, a healthcare practitioner may order this test, along with others, to discover an electrolyte imbalance. When there are symptoms involving the heart, potassium in particular might be assessed.

The potassium test can also be used to track the effects of medicines that cause potassium loss in the kidneys, such as diuretics, or pharmaceuticals that reduce potassium clearance from the body, resulting in high potassium levels.

What do my Potassium test results mean?

Conditions that cause high potassium levels include:

  • Kidney failure
  • The disease Addison's
  • Tissue damage Infection
  • Diabetes
  • Dehydration
  • Too much potassium intake
  • Excessive IV potassium in individuals receiving intravenous fluids
  • Nonsteroidal anti-inflammatory medicines, ACE inhibitors, beta blockers, and potassium-sparing diuretics are among the pharmaceuticals that can induce excessive potassium in a tiny percentage of persons.

Low potassium levels can be detected in a variety of situations, including:

  • Conn syndrome
  • Diarrhea and vomiting.
  • An acetaminophen overdose complication
  • When someone with diabetes takes insulin, their potassium level may drop, especially if they have not properly managed their diabetes.
  • Low potassium is usually caused by "water pills," and if someone is taking them, their potassium level will be checked on a regular basis by their healthcare professional.

Furthermore, medicines including corticosteroids, beta-adrenergic agonists like isoproterenol, alpha-adrenergic antagonists like clonidine, antibiotics like gentamicin and carbenicillin, and the antifungal amphotericin B can cause potassium loss.

Urine potassium concentrations must be compared to blood potassium levels. Because the body generally removes excess potassium, the concentration in the urine may be higher than the blood. When the body loses too much potassium, it can also show up in the urine; in this situation, the blood level will be normal to low. If potassium levels in the blood are low due to insufficient consumption, urine concentrations will be low as well.

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

Description: Transferrin is a blood test used to measure the amount of transferrin in the blood's serum. It is used to evaluate if there is a proper amount of iron being transport throughout the body. A test called Total Iron Binding Capacity, or TIBC, will tell you how much of that transferrin is capable of transporting, or binding to the iron in the blood.

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Fasting for at least 12 hours is required

When is a Transferrin test ordered?

When a doctor wants to analyze or monitor a person's nutritional health, a transferrin test may be ordered along with additional tests like prealbumin.

What does a Transferrin blood test check for?

The primary protein in the blood that bonds to iron and transfers it across the body is transferrin. Total iron binding capacity, unsaturated iron binding capacity, and transferrin saturation are all measures of how much transferrin is available to bind to and transport iron.

The transferrin serum test, along with TIBC, UIBC, and transferrin saturation, measures the blood's ability to bind and transport iron, and is an indicator of iron storage.

Lab tests often ordered with a Transferrin test:

  • Iron Total
  • Iron Total and Total Iron Binding Capacity
  • Ferritin
  • Complete Blood Count (CBC)
  • Hemoglobin
  • Hematocrit
  • Reticulocyte Count

Conditions where a Transferrin test is recommended:

  • Iron Deficiency Anemia
  • Hemochromatosis
  • Liver Disease
  • Malnutrition

How does my health care provider use a Transferrin test?

When assessing a person's nutritional state or liver function, a transferrin test is commonly performed. Transferrin will be low in people with liver disease because it is produced in the liver. Transferrin levels fall when there isn't enough protein in the diet, so this test is used to keep track of your diet.

What do my transferrin test results mean?

The findings of transferrin testing are frequently compared to the results of other iron tests.

If you have the following conditions, you may have a low transferrin level:

  • Hemochromatosis
  • Anemia caused by a build-up of iron in the body can cause a variety of symptoms.
  • Malnutrition
  • Inflammation
  • Hepatitis
  • A kidney ailment that causes protein loss in the urine such as nephrotic syndrome

When there is an iron deficit, transferrin saturation decreases, and when there is an overabundance of iron, such as in iron overload or poisoning, it increases.

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

Description: This test will measure the amount of retinol in the blood. It can be used to determine if there is too much vitamin A or not enough vitamin A in the blood.

Also Known As: Retinol test

Collection Method: Blood draw

Specimen Type: Serum

Test Preparation: Overnight fasting is preferred

When is a Vitamin A test ordered?

When a person shows signs and symptoms that point to a vitamin A deficiency or is malnourished in general, a vitamin A test may be recommended. The following are some of the signs and symptoms:

  • Blindness at night
  • Eyes, skin, and hair that are dry
  • Damage to and ulcers on the cornea
  • Lesions and thickening of the skin
  • On the lining of the eyes, there are grayish patches.
  • Infections that recur
  • Anemia

When a person has an illness that causes malabsorption of nutrients, testing may be done on a regular basis to check vitamin A status and ensure that the individual is getting enough vitamin A. Inadequate vitamin A absorption has been linked to the following diseases:

  • Celiac disease
  • Irritable bowel syndrome
  • Crohn's disease

When a person exhibits signs and symptoms of vitamin A poisoning and their medical history is compatible with the ingestion of vitamin A-containing foods or supplements, testing may be undertaken. The following are some of the indications and symptoms of vitamin A toxicity:

  • Headache
  • Vomiting and nausea
  • Vision that is doubled or blurred
  • Fatigue
  • Weakness
  • Dizziness
  • Seizures
  • Irritability
  • Muscle ache
  • Joint and bone discomfort
  • Loss of weight
  • Hair loss
  • Dryness of the mucous membranes
  • Itching
  • Dysfunction of the liver
  • At the corners of the mouth, there are cracks
  • Tongue inflammation

What does a Vitamin A blood test check for?

This test examines the amount of retinol in the blood; in animals, retinol is the most common form of vitamin A. Vitamin A is necessary for proper vision, skin growth and integrity, bone formation, immunological function, and embryonic development. It is essential for the production of photoreceptors in the eyes as well as the maintenance of the lining of the eye's surface and other mucous membranes. Vitamin A deficiency can impair night vision, induce eye damage, and even result in blindness in severe situations. Vitamin A excesses, whether acute or chronic, can be hazardous, resulting in a variety of symptoms and, in rare cases, birth abnormalities.

Vitamin A is not produced by the body, so it must be obtained from food. Vitamin A is found in meat, while carotene is found in vegetables and fruits. Vitamin A is stored in the liver and adipose tissues, with healthy people storing up to a year's worth. Through a feedback system that releases vitamin A from storage as needed and enhances or decreases the efficiency of dietary vitamin A absorption, the body maintains a reasonably steady concentration in the blood.

Vitamin A deficiency is uncommon in the United States, but it is a major health issue in many underdeveloped countries where people have poor diets. Night blindness is one of the first indicators of vitamin A insufficiency. The World Health Organization estimated that night blindness impacted as many as 5 million preschool age children and nearly 10 million pregnant women in a 1995-2005 study of the global incidence of vitamin A deficiency in populations at risk. In addition, they calculated that 190 million preschool children and 19 million pregnant women were at danger of vitamin A deficiency due to low retinol levels, which indicated a lack of vitamin A supply.

Deficits are most common among malnourished people, those with malabsorption disorders such celiac disease, cystic fibrosis, or chronic pancreatitis, the elderly, and those with alcoholism and liver disease in the United States.

Overuse of vitamin supplements is the leading cause of vitamin A toxicity. It can, however, happen when the diet contains a significant amount of vitamin A-rich foods, such as liver.

Lab tests often ordered with a Vitamin A test:

  • Complete Blood Count (CBC)
  • Comprehensive Metabolic Panel (CMP)
  • Vitamin B12
  • Folate
  • Vitamin D
  • Iron Total
  • Iron and TIBC

Conditions where a Vitamin A test is recommended:

  • Malnutrition
  • Celiac Disease
  • Cystic Fibrosis
  • Pancreatitis
  • Anemia
  • Alcoholism
  • Liver Disease
  • Malabsorption

How does my health care provider use a Vitamin A test?

Vitamin A testing is used to diagnose vitamin A deficiency in patients who have symptoms like night blindness or who have disorders that limit nutritional absorption in the intestine and are at risk of deficiency. Vitamin A deficiency is uncommon in the United States, hence testing for this purpose is uncommon. Testing is sometimes performed to detect hazardous levels of vitamin A induced by ingesting high doses of the vitamin.

Vitamin A excesses, whether acute or chronic, can be hazardous, resulting in a variety of symptoms and, in rare cases, birth abnormalities.

What do my Vitamin A test results mean?

A normal vitamin A blood level suggests that a person has enough vitamin A right now, but it doesn't tell you how much vitamin A is held in reserve. Until vitamin A stores are depleted, the body will keep vitamin A levels in the blood at a reasonably constant level.

A low vitamin A blood test result means that the person's reserves have been depleted and they are deficient.

A high vitamin A blood level implies that the body's ability to retain vitamin A has been exceeded, and that excess vitamin A is currently circulating in the bloodstream, where it may be deposited in other tissues, causing toxicity.

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


Description: Vitamin D, 1,25-Dihydroxy, LC/MS/MS is a blood test that measures calcitriol (1,25-Dihydroxyvitamin) in your blood's serum.

Also Known As: Calcitriol Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Vitamin D 1,25-Dihydroxy test ordered?

When renal illness or problems of the enzyme that converts 25-hydroxyvitamin D to 1,25-dihydroxyvitamin D are suspected, 1,25-dihydroxyvitamin D tests may be requested. This test is only performed in rare cases when calcium levels are high or a person has an illness that produces excessive amounts of vitamin D, such as sarcoidosis or some types of lymphoma.

Vitamin D levels are sometimes evaluated to check therapy success when vitamin D, phosphorus, calcium or magnesium supplementation is required.

What does a Vitamin D 1,25-Dihydroxy blood test check for?

Vitamin D is a group of chemicals that are necessary for the healthy development and growth of teeth and bones. The level of vitamin D in the blood is determined by this test.

Vitamin D is tested in the blood in two forms: 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D. The primary form of vitamin D found in the blood is 25-hydroxyvitamin D, which is a relatively inactive precursor to the active hormone 1,25-dihydroxyvitamin D. 25-hydroxyvitamin D is routinely evaluated to assess and monitor vitamin D status in humans due to its longer half-life and higher concentration.

Endogenous vitamin D is created in the skin when exposed to sunshine, whereas exogenous vitamin D is taken through foods and supplements. Vitamin D2 and vitamin D3 are two separate kinds of vitamin D with somewhat different chemical structures. Fortified foods, as well as most vitamin preparations and supplements, include the D2 form. The type of vitamin D3 produced by the body is also used in some supplements. When the liver and kidneys convert vitamin D2 and D3 into the active form, 1,25-dihydroxyvitamin D, they are equally effective.

Vitamin D's major function is to assist balance calcium, phosphorus, and magnesium levels in the blood. Vitamin D is necessary for bone growth and health; without it, bones become fragile, misshapen, and unable to mend themselves properly, leading to disorders such as rickets in children and osteomalacia in adults. Vitamin D has also been proven to influence the growth and differentiation of a variety of other tissues, as well as to aid in immune system regulation. Other illnesses, such as autoimmune and cancer, have been linked to vitamin D's other roles.

According to the Centers for Disease Control and Prevention, two-thirds of the US population has adequate vitamin D, while one-quarter is at risk of inadequate vitamin D and 8% is at risk of insufficiency, as defined by the Institute of Medicine's Dietary Reference Intake.

The elderly or obese, persons who don't receive enough sun exposure, people with darker skin, and people who take certain drugs for lengthy periods of time are all at risk of insufficiency. Adequate sun exposure is usually defined as two intervals of 5-20 minutes each week. Vitamin D can be obtained through dietary sources or supplements by people who do not get enough sun exposure.

Lab tests often ordered with a Vitamin D 1,25-Dihydroxy test:

  • Vitamin D 25-Hydroxy (D2 and D3)
  • Calcium
  • Phosphorus
  • PTH
  • Magnesium
  • Bone Markers
  • Trace Minerals

Conditions where a Vitamin D 1,25-Dihydroxy test is recommended:

  • Osteoporosis
  • Kidney Disease
  • Lymphoma
  • Autoimmune Disorders
  • Cystic Fibrosis
  • Celiac Disease
  • Malabsorption
  • Malnutrition

How does my health care provider use a Vitamin D 1,25-Dihydroxy test?

Determine whether a deficit or excess of vitamin D is causing bone weakening, deformity, or improper calcium metabolism.

Because PTH is required for vitamin D activation, it can aid in diagnosing or monitoring problems with parathyroid gland function.

Because vitamin D is a fat-soluble vitamin that is absorbed from the intestine like a fat, it can help monitor the health of people with conditions that interfere with fat absorption, such as cystic fibrosis and Crohn's disease.

People who have had gastric bypass surgery and may not be able to absorb adequate vitamin D should be closely monitored.

When vitamin D, calcium, phosphorus, and/or magnesium supplementation is suggested, it can help assess the success of the treatment.

What do my Vitamin D, 1,25-Dihydroxy test results mean?

In kidney illness, a low level of 1,25-dihydroxyvitamin D is one of the first alterations to appear in people with early renal failure.

A high amount of 1,25-dihydroxyvitamin D can arise when there is an excess of parathyroid hormone or when there are disorders that can produce 1,25-dihydroxyvitamin D outside of the kidneys, such as sarcoidosis or some lymphomas.

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


Brief Description: A Vitamin D test is a blood test used to determine if you have a Vitamin D deficiency and to monitor Vitamin D levels if you are on supplementation.

Also Known As: Ergocalciferol Test, Vitamin D2 Test, Cholecalciferol Test, Vitamin D3 Test, Calcidiol Test, 25-hydroxyvitamin D Test, Calcifidiol Test, 25-hydroxy-vitamin D Test, Vitamin D Total Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Fasting preferred, but not required.

When is a Vitamin D test ordered?

When calcium levels are inadequate and/or a person exhibits symptoms of vitamin D deficiency, such as rickets in children and bone weakening, softness, or fracture in adults, 25-hydroxyvitamin D is frequently ordered to rule out a vitamin D deficit.

When a person is suspected of having a vitamin D deficiency, the test may be requested. Vitamin D deficiency is more common in older folks, people who are institutionalized or homebound and/or have minimal sun exposure, people who are obese, have had gastric bypass surgery, and/or have fat malabsorption. People with darker skin and breastfed babies are also included in this category.

Before starting osteoporosis medication, 25-hydroxyvitamin D is frequently requested.

The type of vitamin D3 produced by the body is also used in some supplements. When the liver and kidneys convert vitamin D2 and D3 into the active form, 1,25-dihydroxyvitamin D, they are equally effective.

Some tests may not differentiate between the D2 and D3 forms of vitamin D and just report the total result. Newer methods, on the other hand, may record D2 and D3 levels separately and then sum them up to get a total level.

Vitamin D's major function is to assist balance calcium, phosphorus, and magnesium levels in the blood.

When vitamin D, calcium, phosphorus, and/or magnesium supplementation is suggested, it can help assess the success of the treatment.

What do my Vitamin D results result mean?

Despite the fact that vitamin D techniques differ, most laboratories use the same reference intervals. Because toxicity is uncommon, researchers have focused on the lower limit and what cut-off for total 25-hydroxyvitamin D shortage implies.

A low blood level of 25-hydroxyvitamin D could indicate that a person isn't getting enough sunlight or dietary vitamin D to meet his or her body's needs, or that there's an issue with absorption from the intestines. Seizure medications, notably phenytoin, might occasionally interfere with the liver's generation of 25-hydroxyvitamin D.

Vitamin D insufficiency has been linked to an increased risk of some malignancies, immunological illnesses, and cardiovascular disease.

Excessive supplementation with vitamin pills or other nutritional supplements frequently results in a high level of 25-hydroxyvitamin D.

Unbound calcium is typically measured when the balance between free and bound calcium is disrupted, which can occur with:

  • Extremely low albumin levels
  • Major surgeries
  • Blood transfusions
  • Critical illnesses

Those with low ionized calcium may experience muscle spasms or numbness around the mouth or in their hands and feet.

The average processing time is 1-2 business days, and it has no fasting requirements.

Ceruloplasmin and Copper

Ceruloplasmin is a protein containing copper, an essential mineral for a variety of bodily functions.

Ceruloplasmin and copper blood tests help diagnose diseases that cause abnormal levels of copper in the body, including Wilson's Disease, Celiac Disease, and Cystic Fibrosis. 

The average processing time for a Ceruloplasmin blood test is 4-5 days. It has no fasting requirements and is often accompanied by a copper blood test, which has an average processing time of 2-4 days.

Complete Blood Count and Hemoglobin 

Hemoglobin (Hgb) and Complete Blood Count (CBC) are part of routine general health blood work.

Hgb is a protein that carries oxygen throughout the body. 

Low Hgb levels can indicate anemia, nutritional deficiencies, bone marrow disorders, or kidney damage. High Hgb levels may indicate dehydration, lung disease, heart disease, or kidney tumors. 

The average processing time for Hgb and CBC blood tests is typically 1 day.

Iron and Total Iron Binding Capacity

Total Iron Binding Capacity is a blood test that measures the amount of iron you have in your blood and how well the protein transferrin carries the iron in your blood.

The average processing time for a TIBC test is 1-2 days.

Iron helps muscles store and use oxygen, and too little iron can lead to iron-deficiency anemia. Low iron levels may occur from blood loss, poor diet, or inefficient absorption of iron from food.

Ferritin

Ferritin is a protein that stores iron inside the body's cells. By measuring ferritin, doctors can indirectly measure the amount of iron in your blood.

Ferritin blood tests are often ordered after a person receives abnormal CBC results and may be accompanied by an Iron and TIBC Test to check for iron deficiency or overload.

The average processing time of a Ferritin blood test is typically 1 day.

Magnesium, RBC

Magnesium is essential for almost all of the body's chemical processes, including the maintenance of the body's:

  • Muscle and nerve function
  • Bone strength
  • Heart function
  • Blood pressure
  • Blood sugar levels
  • Immune system

Magnesium deficiencies may occur in cases of malnutrition and malabsorption. Magnesium excess may occur from ingesting antacids containing magnesium or when the kidneys excrete magnesium ineffectively.

The average processing time for a Magnesium RBC lab test is 4-5 days.

Potassium, RBC

Potassium is an electrolyte that is important for body and muscle function. Abnormal potassium levels may indicate kidney disease, diabetes, or thyroid disorder, among other conditions.

The average processing time is 5 to 7 days.

Transferrin

Transferrin is a protein that helps carry iron to various parts of the body. It directly measures iron-binding capacity. This makes it useful in the assessment of iron balance, deficiency, and overload.

The typical processing time is 1-3 days, and it is necessary to fast 8-12 hours before blood sample collection.

Vitamin A (Retinol)

Vitamin A is essential for:

  • Healthy skin
  • Healthy eyes and vision
  • Bone growth
  • Immune function
  • Embryonic development

Vitamin A deficiency may occur if a person does not eat enough meat, fruits, and vegetables. Disorders associated with malnutrition or malabsorption can also cause it.

Symptoms of Vitamin A deficiency include:

  • Night blindness
  • Dry eyes, skin, or hair
  • Skin lesions
  • Anemia
  • Gray spots on the eye's lining
  • Repeated infections

Retinol tests also check for Vitamin A toxicity. This typically occurs because of supplement overuse or a diet that consists largely of Vitamin A rich foods.

The average processing time for a Vitamin A (retinol) lab test is 3-7 business days. It is necessary to fast for 12 hours before having your sample collected.

Vitamin D, 1, 25-Dihydroxy

Vitamin D, 1, 25-Dihydroxy is typically ordered to test for an excess of Vitamin D. This can occur with conditions such as parathyroid disorder and kidney failure.

The average processing time is 5-7 business days.

Vitamin D, 25-Hydroxy

Vitamin D, 25-Hydroxy is necessary for teeth and bones to have proper growth and health. It also helps the immune system and bodily tissues develop healthily.

A Vitamin D lab test is usually ordered to test for symptoms of vitamin D deficiency. Vitamin D deficiency is usually caused by insufficient sun exposure or conditions like Cystic Fibrosis and Crohn's Disease. Symptoms of Vitamin D deficiency include:

  • Tiredness
  • Weakness
  • Aches and pains
  • Frequent infections

The typical processing time is 1-3 days, and it has no fasting requirements.

Zinc

Zinc is essential for a strong immune system, normal growth and cell reproduction, and healing from injuries.

Zinc deficiency occurs from a lack of dietary intake or an excess of certain minerals, which prevent the body from effectively absorbing zinc. It may also occur with conditions such as Crohn's Disease and Sickle Cell Anemia.

Symptoms include:

  • Recurring infections
  • Decreased speed of healing
  • Severe diarrhea
  • Thinning hair
  • Recurring skin rashes or acne
  • Decreased ability to taste or smell

The typical processing time is 3-5 days, and there are no fasting requirements.
