Vasculitis

Vasculitis Lab Tests  and health information

Are you suffering from a chronic illness?

Order a vasculitis blood test to evaluate if you have inflammation and damage to your blood vessels.

If so, you might be wondering if it’s time to get tested for vasculitis. Vasculitis is an inflammation of blood vessels that can affect the kidneys and other organs in your body. It can also cause damage to large arteries or veins.

If you’re experiencing any of the following, a vasculitis blood test may be able to help diagnose your condition. Symptoms include fatigue, weight loss, fever, joint pain, and skin rashes. Some people also experience abdominal pain or nausea with vomiting and diarrhea. If you’ve been diagnosed with an autoimmune disease such as lupus or rheumatoid arthritis, then this test is recommended for further evaluation of your condition.

Testing for vasculitis with blood tests will give you information about red cells in your body that are called erythrocytes (red blood cells), which carry oxygen throughout the body to every cell. The number of red cells in our bodies is important because if they decrease too much, it can lead to anemia (low red cell count). You can also look at the white cells in our bodies called leukocytes (white blood cells) which fight infection by destroying bacteria and viruses that enter our bodies through cuts or other injuries. You can also measure these levels using a complete Blood Count Test panel that includes results for hemoglobin level, hematocrit level, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), platelet count, and white cell differential counts, among others so you can get the information needed to understand it what might be. The ANCA test is used to help diagnose vasculitis. It can also be helpful in differentiating between Wegener’s granulomatosis and microscopic polyangiitis, two types of vasculitis that are very similar. This test measures the level of anti-neutrophil cytoplasmic antibodies (ANCA) in your blood. If these antibodies are found at high levels, it may indicate an autoimmune disorder called systemic necrotizing vasculitides or small vessel vasculitides. These diseases cause inflammation and damage to the smallest blood vessels throughout your body, which can lead to serious complications if not treated properly.

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: The CRP test is used to identify and/or monitor inflammation in patients.

Also Known As: CRP Test, Inflammation test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a C-Reactive Protein test ordered?

When a person's medical history and signs and symptoms indicate that they may have a significant bacterial infection, a CRP test may be recommended. When a newborn displays signs of infection or when a person has sepsis symptoms including fever, chills, and rapid breathing and heart rate, it may be ordered.

It's also commonly requested on a regular basis to check illnesses like rheumatoid arthritis and lupus, and it's routinely repeated to see if medication is working. This is especially effective for inflammation issues because CRP levels decrease as inflammation decreases.

What does a C-Reactive Protein blood test check for?

C-reactive protein is a protein produced by the liver and released into the bloodstream within a few hours following tissue injury, infection, or other inflammatory event. After trauma or a heart attack, with active or uncontrolled autoimmune illnesses, and with acute bacterial infections like sepsis, markedly higher levels are reported. CRP levels can rise by a thousand-fold in response to inflammatory diseases, and their elevation in the blood can occur before pain, fever, or other clinical signs. The test detects inflammation caused by acute situations or monitors disease activity in chronic diseases by measuring the level of CRP in the blood.

The CRP test is not a diagnostic tool, although it can tell a doctor if inflammation is occurring. This information can be combined with other indicators like signs and symptoms, a physical exam, and other tests to establish whether someone has an acute inflammatory disorder or is having a flare-up of a chronic inflammatory disease. The health care provider may next do additional tests and treatment.

This CRP test should not be confused with the hs-CRP test. These are two separate CRP tests, each of which measures a different range of CRP levels in the blood for different purposes.

Lab tests often ordered with a C-Reactive Protein test:

  • Sed Rate (ESR)
  • Procalcitonin
  • ANA
  • Rheumatoid Factor
  • Complement

Conditions where a C-Reactive Protein test is recommended:

  • Arthritis
  • Autoimmune Disorders
  • Pelvic Inflammatory Disease
  • Inflammatory Bowel Disease
  • Sepsis
  • Vasculitis
  • Systemic Lupus Erythematosus
  • Meningitis and Encephalitis

Commonly Asked Questions:

How does my health care provider use a C-Reactive Protein test?

A health practitioner uses the C-reactive protein test to diagnose inflammation. CRP is an acute phase reactant, a protein produced by the liver and released into the bloodstream within a few hours following tissue injury, infection, or other inflammatory event. The CRP test is not a diagnostic test for any ailment, but it can be used in conjunction with other tests to determine whether a person has an acute or chronic inflammatory disorder.

CRP, for example, can be used to detect or track substantial inflammation in someone who is suspected of having an acute ailment like:

  • Sepsis is a dangerous bacterial infection.
  • An infection caused by a fungus
  • Inflammation of the pelvis

People with chronic inflammatory diseases can use the CRP test to detect flare-ups and/or see if their medication is working. Here are a few examples:

  • Inflammatory bowel disease
  • Arthritis, which can take many forms.
  • Autoimmune disorders, examples include lupus and vasculitis

CRP is occasionally requested in conjunction with an erythrocyte sedimentation rate, another inflammatory test. While the CRP test is not specific enough to diagnose an illness, it does serve as a broad marker for infection and inflammation, alerting doctors to the need for more testing and treatment. A variety of additional tests may be used to determine the source of inflammation, depending on the probable cause.

What do my C-Reactive Protein test results mean?

CRP levels in the blood are usually low.

CRP levels in the blood that are high or rising indicate the existence of inflammation, but they don't tell you where it is or what's causing it. A high CRP level can establish the presence of a severe bacterial infection in people who are suspected of having one. High levels of CRP in persons with chronic inflammatory disorders indicate a flare-up or that treatment isn't working.

When the CRP level rises and then falls, it indicates that the inflammation or infection is diminishing and/or responding to treatment.

Is there anything else I should know about C-Reactive Protein?

CRP levels can rise during pregnancy, as well as with the use of birth control tablets or hormone replacement therapy. Obese people have also been found to have higher CRP levels.

In the presence of inflammation, the erythrocyte sedimentation rate test will also rise; however, CRP rises first and then falls faster than the ESR.

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


Description: A Comprehensive Metabolic Panel or CMP is a blood test that is a combination of a Basic Metabolic Panel, a Liver Panel, and electrolyte panel, and is used to screen for, diagnose, and monitor a variety of conditions and diseases such as liver disease, diabetes, and kidney disease. 

Also Known As: CMP, Chem, Chem-14, Chem-12, Chem-21, Chemistry Panel, Chem Panel, Chem Screen, Chemistry Screen, SMA 12, SMA 20, SMA 21, SMAC, Chem test

Collection Method: 

Blood Draw 

Specimen Type: 

Serum 

Test Preparation: 

9-12 hours fasting is preferred. 

When is a Comprehensive Metabolic Panel test ordered:  

A CMP is frequently requested as part of a lab test for a medical evaluation or yearly physical. A CMP test consists of many different tests that give healthcare providers a range of information about your health, including liver and kidney function, electrolyte balance, and blood sugar levels. To confirm or rule out a suspected diagnosis, abnormal test results are frequently followed up with other tests that provide a more in depth or targeted analysis of key areas that need investigating. 

What does a Comprehensive Metabolic Panel blood test check for? 

The complete metabolic panel (CMP) is a set of 20 tests that provides critical information to a healthcare professional about a person's current metabolic status, check for liver or kidney disease, electrolyte and acid/base balance, and blood glucose and blood protein levels. Abnormal results, particularly when they are combined, can suggest a problem that needs to be addressed. 

The following tests are included in the CMP: 

  • Albumin: this is a measure of Albumin levels in your blood. Albumin is a protein made by the liver that is responsible for many vital roles including transporting nutrients throughout the body and preventing fluid from leaking out of blood vessels. 

  • Albumin/Globulin Ratio: this is a ratio between your total Albumin and Globulin  

  • Alkaline Phosphatase: this is a measure of Alkaline phosphatase or ALP in your blood. Alkaline phosphatase is a protein found in all body tissues, however the ALP found in blood comes from the liver and bones. Elevated levels are often associated with liver damage, gallbladder disease, or bone disorder. 

  • Alt: this is a measure of Alanine transaminase or ALT in your blood. Alanine Aminotransferase is an enzyme found in the highest amounts in the liver with small amounts in the heart and muscles. Elevated levels are often associated with liver damage. 

  • AST: this is a measure of Aspartate Aminotransferase or AST. Aspartate Aminotransferase is an enzyme found mostly in the heart and liver, with smaller amounts in the kidney and muscles. Elevated levels are often associated with liver damage. 

  • Bilirubin, Total: this is a measure of bilirubin in your blood. Bilirubin is an orange-yellowish waste product produced from the breakdown of heme which is a component of hemoglobin found in red blood cells. The liver is responsible for removal of bilirubin from the body. 

  • Bun/Creatinine Ratio: this is a ratio between your Urea Nitrogen (BUN) result and Creatinine result.  

  • Calcium: this is a measurement of calcium in your blood. Calcium is the most abundant and one of the most important minerals in the body as it essential for proper nerve, muscle, and heart function. 

  • Calcium: is used for blood clot formation and the formation and maintenance of bones and teeth. 

  • Carbon Dioxide: this is a measure of carbon dioxide in your blood. Carbon dioxide is a negatively charged electrolyte that works with other electrolytes such as chloride, potassium, and sodium to regulate the body’s acid-base balance and fluid levels.  

  • Chloride: this is a measure of Chloride in your blood. Chloride is a negatively charged electrolyte that works with other electrolytes such as potassium and sodium to regulate the body’s acid-base balance and fluid levels. 

  • Creatinine: this is a measure of Creatinine levels in your blood. Creatinine is created from the breakdown of creatine in your muscles and is removed from your body by the kidneys. Elevated creatinine levels are often associated with kidney damage. 

  • Egfr African American: this is a measure of how well your kidneys are functioning. Glomeruli are tiny filters in your kidneys that filter out waste products from your blood for removal while retaining important substances such as nutrients and blood cells. 

  • Egfr Non-Afr. American: this is a measure of how well your kidneys are functioning. Glomeruli are tiny filters in your kidneys that filter out waste products from your blood for removal while retaining important substances such as nutrients and blood cells. 

  • Globulin: this is a measure of all blood proteins in your blood that are not albumin. 

  • Glucose: this is a measure of glucose in your blood. Glucose is created from the breakdown of carbohydrates during digestion and is the body’s primary source of energy. 

  • Potassium: this is a measure of Potassium in your blood. Potassium is an electrolyte that plays a vital role in cell metabolism, nerve and muscle function, and transport of nutrients into cells and removal of wastes products out of cells. 

  • Protein, Total: this is a measure of total protein levels in your blood. 
    Sodium: this is a measure of Sodium in your blood. Sodium is an electrolyte that plays a vital role in nerve and muscle function. 

  • Sodium: this is a measure of sodium in your blood's serum. Sodium is a vital mineral for nerve and muscle cell function.

  • Urea Nitrogen (Bun): this is a measure of Urea Nitrogen in your blood, also known as Blood UreaNitrogen (BUN). Urea is a waste product created in the liver when proteins are broken down into amino acids. Elevated levels are often associated with kidney damage. 

Lab tests often ordered with a Comprehensive Metabolic Panel test: 

  • Complete Blood Count with Differential and Platelets
  • Iron and Total Iron Binding Capacity
  • Lipid Panel
  • Vitamin B12 and Folate
  • Prothrombin with INR and Partial Thromboplastin Times
  • Sed Rate (ESR)
  • C-Reactive Protein

Conditions where a Comprehensive Metabolic Panel test is recommended: 

  • Diabetes
  • Kidney Disease
  • Liver Disease
  • Hypertension

Commonly Asked Questions: 

How does my health care provider use a Comprehensive Metabolic Panel test? 

The comprehensive metabolic panel (CMP) is a broad screening tool for assessing organ function and detecting diseases like diabetes, liver disease, and kidney disease. The CMP test may also be requested to monitor known disorders such as hypertension and to check for any renal or liver-related side effects in persons taking specific drugs. If a health practitioner wants to follow two or more separate CMP components, the full CMP might be ordered because it contains more information. 

What do my Comprehensive Metabolic Panel test results mean? 

The results of the tests included in the CMP are usually analyzed together to look for patterns. A single abnormal test result may indicate something different than a series of abnormal test findings. A high result on one of the liver enzyme tests, for example, is not the same as a high result on several liver enzyme tests. 

Several sets of CMPs, frequently performed on various days, may be examined to gain insights into the underlying disease and response to treatment, especially in hospitalized patients. 

Out-of-range findings for any of the CMP tests can be caused by a variety of illnesses, including kidney failure, breathing issues, and diabetes-related complications, to name a few. If any of the results are abnormal, one or more follow-up tests are usually ordered to help determine the reason and/or establish a diagnosis. 

Is there anything else I should know? 

A wide range of prescription and over-the-counter medications can have an impact on the results of the CMP's components. Any medications you're taking should be disclosed to your healthcare professional. Similarly, it is critical to provide a thorough history because many other circumstances can influence how your results are interpreted. 

What's the difference between the CMP and the BMP tests, and why would my doctor choose one over the other? 

The CMP consists of 14 tests, while the basic metabolic panel (BMP) is a subset of those with eight tests. The liver (ALP, ALT, AST, and bilirubin) and protein (albumin and total protein) tests are not included. If a healthcare provider wants a more thorough picture of a person's organ function or to check for specific illnesses like diabetes or liver or kidney disease, he or she may prescribe a CMP rather than a BMP. 

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

Please note the following regarding BUN/Creatinine ratio: 

The lab does not report the calculation for the BUN/Creatinine Ratio unless one or both biomarkers’ results fall out of the published range. 

If you still wish to see the value, it's easy to calculate. Simply take your Urea Nitrogen (BUN) result and divide it by your Creatinine result.  

As an example, if your Urea Nitrogen result is 11 and your Creatinine result is 0.86, then you would divide 11 by 0.86 and get a BUN/Creatinine Ratio result of 12.79.

Description: A Creatinine test is a blood test that is used to evaluate the health of your kidneys and diagnose and monitor the treatment of kidney disease.

Also Known As: Create Test, Blood Creatinine Test, Serum Creatinine Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Creatinine test ordered?

During a health assessment, creatinine may be requested as part of a complete or basic metabolic panel. It may be ordered if a person is seriously ill or if a doctor feels that their kidneys aren't functioning properly.

When someone has a known renal condition or a disease that may impact kidney function, a creatinine blood test, coupled with a BUN test and urine albumin, may be ordered at regular intervals. When a CT scan is planned, before to and during some medication therapy, and before and after dialysis, both BUN and creatinine may be requested to assess the effectiveness of treatments.

What does a Creatinine blood test check for?

Creatinine is a waste product created by muscles when a molecule called creatine is broken down. The kidneys eliminate creatinine from the body by filtering almost all of it from the blood and excreting it in the urine. The level of creatinine in the blood and/or urine is measured in this test.

Creatine is a component of the energy-producing cycle that allows muscles to contract. The body produces both creatine and creatinine at a roughly steady rate. Because the kidneys filter almost all creatinine from the blood and excrete it in the urine, blood levels are usually an excellent predictor of how well the kidneys are operating. The amount produced is determined by the person's size and muscular mass. As a result, men's creatinine levels will be slightly higher than women's and children's.

A blood creatinine test's results can be combined with those from other tests, such as a 24-hour urine creatinine test, to produce calculations that are used to assess kidney function.

Lab tests often ordered with a Creatinine test:

  • BUN (Blood Urea Nitrogen)
  • Creatinine Clearance
  • Comprehensive Metabolic Panel (CMP)
  • Basic Metabolic Panel (BMP)
  • Urinalysis
  • Microalbumin and Creatinine Ratio
  • Cystatin C with eGFR
  • Beta-2 Microglobulin
  • Urine Protein

Conditions where a Creatinine test is recommended:

  • Kidney Disease
  • Diabetes
  • Proteinuria
  • Hypertension

How does my health care provider use a Creatinine test?

Kidney function is assessed with a creatinine blood test. It's usually requested in conjunction with a BUN test or as part of a basic or comprehensive metabolic panel, which consists of a series of tests designed to assess the operation of the body's primary organs. BMP or CMP tests are used to screen healthy persons during normal physical exams, as well as to help evaluate people who are acutely or chronically ill in the emergency room and/or hospital. Creatinine testing is sometimes done as part of a renal panel to assess kidney function.

Creatinine is a waste product created by muscles when a molecule called creatine is broken down. Because the kidneys filter almost all creatinine from the blood and discharge it into the urine, blood levels are usually an excellent predictor of how well the kidneys are operating.

The kidneys are a pair of bean-shaped organs placed on the right and left sides of the back at the bottom of the ribcage. Nephrons are a million microscopic blood filtering units found within them. Blood is continuously filtered by a small cluster of looping blood arteries called a glomerulus in each nephron. Water and tiny molecules flow through the glomerulus, but blood cells and bigger molecules are retained. Each glomerulus has a little tube attached to it that gathers the fluid and molecules that flow through it and then reabsorbs what the body can use. Urine is formed from the residual waste.

If the creatinine and BUN tests are abnormal, or if the patient has an underlying condition that affects the kidneys, such as diabetes or high blood pressure, creatinine and BUN tests may be used to monitor renal functionality and therapy effectiveness. Before some procedures, such as a CT scan, that may necessitate the use of medicines that can harm the kidneys, blood creatinine and BUN tests may be requested to assess renal function.

Creatinine test results can be utilized in calculations to determine renal function.

The estimated glomerular filtration rate, used as a screen to search for signs of early kidney damage, is calculated using blood creatinine readings, as well as age, weight, and sex.

What do my Creatinine test results mean?

Elevated creatinine levels in the blood indicate renal disease or other disorders affecting kidney function.

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


Description: Sed Rate is a blood test that is used to measure the rate that red blood cells fall to the bottom of a test tube. The measurement is based how many cells fall within one hour. This test can be used to determine infection or inflammation.

Also Known As: Erythrocyte Sedimentation Rate Test, ESR Test, Sed Rate Test, Sedimentation Rate Test, Westergren Sedimentation Rate Test

Collection Method: Blood Draw

Specimen Type: Whole Blood

Test Preparation: No preparation required

When is a Sed Rate test ordered?

When a condition or disease is believed to be causing inflammation in the body, an ESR may be ordered. Several inflammatory illnesses can be identified using this test. It may be requested, for example, if arthritis is suspected of producing joint inflammation and pain, or if inflammatory bowel disease is suspected of causing digestive symptoms.

When a person develops symptoms of polymyalgia rheumatica, systemic vasculitis, or temporal arteritis, such as headaches, neck or shoulder discomfort, anemia, pelvic pain, poor appetite, joint stiffness, and unexplained weight loss, a doctor may recommend an ESR. To follow the development of specific illnesses, the sed rate test can also be routinely ordered.

A health practitioner may wish to repeat the ESR before undertaking a full workup to look for disease.

What does a Sed Rate blood test check for?

The erythrocyte sedimentation rate is a test that evaluates the degree of inflammation in the body indirectly. The test evaluates the rate at which erythrocytes fall in a blood sample that has been placed in a tall, thin, vertical tube. The millimeters of clear fluid present at the upper portion of the tube after one hour are reported as the results.

When a drop of blood is inserted in a tube, the red blood cells settle out slowly, leaving just a small amount of transparent plasma. In the presence of an increased number of proteins, particularly proteins known as acute phase reactants, red cells settle at a faster pace. Inflammation raises the levels of acute phase reactants such as C-reactive protein and fibrinogen in the blood.

An inherent component of the immune system's response is inflammation. It could be chronic, showing symptoms over time with conditions like autoimmune illnesses or cancer, or acute, showing symptoms right away after a shock, injury, or infection.

The ESR is a non-specific indication that can rise in a number of disorders; it is not a diagnostic test. It provides you with a fundamental understanding of whether you have an inflammatory condition or not.

Given the availability of more recent, specialized tests, there have been reservations about the ESR's utility. The ESR test, on the other hand, is commonly used to diagnose and monitor temporal arteritis, systemic vasculitis, and polymyalgia rheumatica. Extremely high ESR values can aid in differentiating between rheumatic diseases. Furthermore, ESR may still be a viable alternative in some cases, such as when newer tests are unavailable in resource-constrained places or while monitoring the progression of a disease.

Lab tests often ordered with a Sed Rate test:

  • C-Reactive Protein
  • ANA
  • Rheumatoid Factor

Conditions where a Sed Rate test is recommended:

  • Vasculitis
  • Autoimmune Disorders
  • Rheumatoid Arthritis
  • Osteoarthritis
  • Celiac Disease
  • Lupus
  • Chronic Fatigue Syndrome
  • Juvenile Rheumatoid Arthritis
  • Inflammatory Bowel Disease

How does my health care provider use a Sed Rate test?

The erythrocyte sedimentation rate is a non-specific, very straightforward test that has been used for many years to detect inflammation associated with infections, malignancies, and autoimmune illnesses.

Because an elevated ESR often indicates the presence of inflammation, but does not tell the health practitioner where the inflammation is in the body or what is causing it, it is referred to as a non-specific test. Other illnesses besides inflammation may have an impact on an ESR. As a result, other tests, such C-reactive protein, are routinely paired with the ESR.

ESR is used to identify temporal arteritis, systemic vasculitis, and polymyalgia rheumatica, among other inflammatory illnesses. A notably elevated ESR is one of the crucial test results used to support the diagnosis.

This test can be used to track disease activity and treatment response in both of the disorders mentioned above, as well as several others including systemic lupus erythematosus.

What do my Sed Rate test results mean?

Because ESR is a non-specific inflammatory measure that is influenced by a variety of circumstances, it must be used in conjunction with other clinical findings, the individual's medical history, and the results of other laboratory tests. The health practitioner may be able to confirm or rule out a suspected illness if the ESR and clinical data match.

Without any signs of a specific condition, a single elevated ESR is usually insufficient to make a medical conclusion. A normal result does not, however, rule out inflammation or illness.

Inflammation, as well as anemia, infection, pregnancy, and aging, can cause a moderately raised ESR.

A severe infection with a rise in globulins, polymyalgia rheumatica, or temporal arteritis are common causes of an extremely high ESR. Depending on the person's symptoms, a health practitioner may employ various follow-up tests, such as blood cultures. Even if there is no inflammation, people with multiple myeloma or Waldenstrom's macroglobulinemia have extraordinarily high ESRs.

Rising ESRs may suggest increased inflammation or a poor response to therapy when monitoring a condition over time; normal or falling ESRs may indicate an adequate response to treatment.

Description: The Hepatic Function Panel is a blood test that measures multiple markers to evaluate the health of your liver.

Also Known As: Liver Profile Test, Liver Function Test, LFT, Liver Enzyme Test, Liver Test, Liver Blood Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Hepatic Function Panel test ordered?

When someone is at risk for liver dysfunction, a liver panel, or one or more of its components, may be requested. Here are a few examples:

  • People who are taking drugs that could harm their liver
  • Those who are alcoholics or who use a lot of alcohol
  • Those who have a history of hepatitis virus exposure, either known or suspected
  • Individuals with a history of liver illness in their families
  • Overweight people, especially those with diabetes and/or high blood pressure

When a person exhibits signs and symptoms of liver disease, a liver panel may be done; however, most people with liver disease do not have any of these symptoms until the disease has been present for years or is very severe. Here are a few examples:

  • Weakness and exhaustion
  • Appetite loss.
  • Vomiting and nausea
  • Swelling and/or pain in the abdomen
  • Jaundice
  • Urine that is dark in color and feces that is light in color
  • Pruritus
  • Diarrhea

To make a diagnosis, no single collection of liver tests is usually used. Several liver panels are frequently done over the course of a few days or weeks to aid in determining the source of the liver illness and assessing its severity.

When liver illness is discovered, the liver panel or one or more of its components can be used to monitor it on a regular basis over time. A liver panel may be conducted on a regular basis to assess the efficacy of treatment for the liver condition.

What does a Hepatic Function Panel blood test check for?

A liver panel is a collection of tests used to diagnose, evaluate, and track the progression of liver illness or damage. The liver is one of the largest organs in the body, and it is placed behind the lower ribs in the upper right section of the belly. Drugs and substances that are detrimental to the body are metabolized and detoxified by the liver. It makes blood clotting factors, proteins, and enzymes, as well as regulating hormone levels and storing vitamins and minerals. Bile, a fluid produced by the liver, is delivered to the small intestine via ducts to aid in fat digestion or to the gallbladder to be stored and concentrated for later use.

Inflammation, scarring, bile duct blockages, liver tumors, and liver dysfunction can all be caused by a range of disorders and infections that cause acute or chronic liver damage. Toxins, alcohol, narcotics, and some herbal medications can all be dangerous. Before signs like jaundice, dark urine, light-colored feces, itching, nausea, exhaustion, diarrhea, and unexplained weight loss or increase appear, there may be considerable liver damage. To reduce damage and preserve liver function, early identification is critical.

The liver panel assesses the enzymes, proteins, and chemicals generated, processed, or removed by the liver, as well as those that are altered by liver injury. Some are produced by damaged liver cells, while others indicate a reduction in the liver's ability to execute one or more activities. When these tests are performed combined, they provide a picture of a person's liver's health, an indication of the severity of any liver injury, changes in liver status over time, and a starting point for further diagnostic testing.

Lab tests often ordered with a Hepatic Function Panel test:

  • GGT
  • Prothrombin Time and International Normalized Ratio
  • LD
  • Hepatitis A Testing
  • Hepatitis B Testing
  • Hepatitis C Testing
  • Emergency and Overdose Drug Testing

  • Cirrhosis

Commonly Asked Questions:

How does my health care provider use a Hepatic Function Panel test?

A liver panel can be performed to check for damage to the liver, especially if someone has an illness or is taking a medication that could harm the liver. For regular screening, a comprehensive metabolic panel, which is commonly conducted as part of a general health checkup, may be ordered instead of a liver panel. The majority of the liver panel is included in this group of tests, as well as other tests that evaluate other organs and systems in the body.

If a person has signs and symptoms that indicate suspected liver malfunction, a liver panel or one or more of its component tests may be done to assist identify liver disease. If a person has a known illness or liver disease, testing may be done at regular intervals to assess the liver's health and the efficiency of any therapies. To evaluate and monitor a jaundiced newborn, a variety of bilirubin tests may be ordered.

Abnormal tests on a liver panel may necessitate a repeat study of one or more tests, or the entire panel, to evaluate if the elevations or declines continue, and/or additional testing to discover the etiology of the liver dysfunction.

Typically, a panel consists of numerous tests performed simultaneously on a blood sample.

What do my Liver Panel Test results mean?

The findings of a liver panel test are not diagnostic of a specific condition; rather, they show that the liver may be malfunctioning. Abnormal liver test results in a person who has no symptoms or recognized risk factors may signal a transitory liver injury or reflect something going on elsewhere in the body, such as the skeletal muscles, pancreas, or heart. It could potentially signal the presence of early liver disease, necessitating more testing and/or periodic monitoring.

The results of liver panels are generally compared. Several sets of results from tests conducted over several days or weeks are sometimes analyzed together to see if a pattern emerges. Each person's test findings will be unique, and they will most likely alter over time. A healthcare professional examines the combined findings of liver tests to learn more about the underlying disease. Further testing is frequently required to discover the cause of the liver damage and/or illness.

Abnormal test results may signal a need to review a person's dosage or medication choice if they are taking medicines that may impact their liver. When a person with liver disease is being monitored, the healthcare provider will look at the findings of the liver panel together to see if liver function or damage is getting worse or better. Increased abnormalities in bilirubin, albumin, and/or PT, for example, may suggest a decline in liver function, whereas steady or improved findings may indicate liver function preservation or improvement.

Description: A Urinalysis complete test is a urine test that is used to screen for, diagnose, and monitor a variety of conditions and diseases urinary tract infections and kidney disorders.

Also Known As: Urine Test, Urine Analysis Test, UA Test, urine microscopic examination Test, Urinalysis Test, Complete Urinalysis Test

Collection Method: Urine Collection

Specimen Type: Urine

Test Preparation: No preparation required

When is a Urinalysis Complete test ordered?

A urinalysis test may be ordered when a person undergoes a routine wellness examination, is admitted into a hospital, will have surgery, or is having a prenatal checkup.

When a person visits a doctor with symptoms of a urinary tract infection or another urinary system ailment, such as kidney disease, a urinalysis will almost certainly be prescribed. The following are some possible signs and symptoms:

  • Pain in the abdomen
  • Backache
  • Urination that is painful or occurs frequently
  • Urine with blood in it

Testing may also be conducted at regular intervals to track the progress of a condition.

What does a Urinalysis Complete test check for?

A urinalysis is a series of examinations done on urine that are physical, chemical, and microscopic. The tests identify and/or measure a number of elements in the urine, including cells, cellular fragments, and microbes. These elements include byproducts of healthy and unhealthy metabolism.

Urine is produced by the kidneys, two fist-sized organs located on either side of the spine near the base of the rib cage. The kidneys help the body regulate its water balance, filter wastes from the blood, and store proteins, electrolytes, and other molecules for later use. To get rid of everything unnecessary, urine travels from the kidneys to the ureters, bladder, and urethra before exiting the body. The color, amount, concentration, and content of urine will change slightly every time a person urinates due to the varied elements in urine, despite the fact that pee is normally yellow and clear.

By screening for components in the urine that aren't typically present and/or monitoring aberrant levels of specific substances, many illnesses can be caught early on. Glucose, bilirubin, protein, red and white blood cells, crystals, and germs are among examples. They could be present because of the following reasons:

  • The body responds to an elevated amount of the substance in the blood by attempting to remove the excess through urine.
  • There is a problem with the kidneys.
  • As with bacteria and white blood cells, there is a urinary tract infection present.

Three separate phases make up a full urinalysis:

  • The color and clarity of the urine are assessed using a visual examination.
  • Chemical examination, which determines the concentration of urine and tests for roughly 9 chemicals that provide useful information about health and disease.
  • Microscopic inspection that identifies and counts the different types of cells, casts, crystals, and other components found in urine, such as bacteria and mucus.

When abnormal results are found, or if a healthcare provider requests it, a microscopic analysis is usually performed.

It may be essential to repeat the test if the findings of a urinalysis are abnormal, and further other urine and blood tests may be needed to help establish a diagnosis, if the results are abnormal.

Lab tests often ordered with a Urinalysis Complete test:

  • Complete Blood Count
  • Iron Total and Total Iron binding capacity
  • Hemoglobin A1c
  • Lipid Panel
  • CMP
  • TSH
  • Urine Culture
  • Bilirubin Fractionated
  • Glucose

Conditions where a Urinalysis Complete test is recommended:

  • Diabetes
  • Kidney Disease
  • Liver Disease
  • Hypertension
  • Pregnancy
  • Hematuria
  • Proteinuria
  • Kidney Stones

How does my health care provider use a Urinalysis Complete test?

A urinalysis is a series of tests that can diagnose a variety of disorders. It can be used to screen for and/or diagnose a variety of illnesses, including urinary tract infections, renal abnormalities, liver diseases, diabetes, and other metabolic disorders, to name a few.

Urinalysis may be used in conjunction with other tests, such as urine albumin, to monitor the progress of treatment in patients with diseases or conditions like diabetes or kidney disease.

What do my urinalysis complete test results mean?

There are numerous ways to interpret the results of a urinalysis. Unusual results are a warning sign that something isn't right and needs further testing.  To connect the urinalysis results with an individual's symptoms and clinical findings and to look for the causes of aberrant findings, other targeted tests must be done, such as a complete blood count, metabolic panel, or urine culture.

It is more likely that a problem must be addressed the higher the concentration of the atypical component, such as noticeably increased levels of protein, glucose, or red blood cells. On the other hand, the outcomes do not inform the medical professional as to what led to the finding or whether it is a transient or ongoing sickness.

A normal urinalysis does not rule out the possibility of disease. Early in a disease process, some persons will not release elevated amounts of a drug, and others will release them irregularly throughout the day, which means they could be overlooked by a single urine sample. Small amounts of substances may be undetectable in very dilute urine.

NOTE: Only measurable biomarkers will be reported.

Decreased C3 and C4 levels may be associated with acute glomerulonephritis, membranoproliferative glomerulonephritis, immune complex disease, active systemic lupus erythematosis, cryoglobulinemia, congenital C4 deficiency and generalized autoimmune disease

Description: The Complement Component C3 test is a blood test used to measure levels of Complement 3 in your blood’s serum as part of autoimmune disease testing.

Also Known As: C3 Test, Complement C3 Test, Complement Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Overnight fasting is preferred

When is a Complement Component C3c test ordered?

When a person exhibits inexplicable edema, inflammation, or indications of an autoimmune condition like SLE, complement testing may be mandated. It may also be requested when a medical professional wants to assess the complement system of a patient who they suspect may have an immune complex-related disease.

When the total complement activity is abnormal, individual complement components may be ordered to help identify which ones are lacking or defective. The most usually prescribed levels are C3 and C4, however when additional shortages are detected, other levels, such C1 inhibitor, may also be required. Because the relative levels are frequently significant, C3 and C4 are frequently ordered together.

Complement testing may be used to provide a general assessment of the severity of an acute or chronic ailment after a diagnosis, with the underlying supposition that the severity is related to the decline in complement levels. When a doctor wishes to track the progression of a problem, they could occasionally order complement testing.

What does a Complement Component C3c blood test check for?

More than 30 circulating blood proteins make up the intricate complement system, which functions to support inflammatory and immunological responses. Its main function is to eliminate invading infections like viruses and bacteria. When the body produces antibodies against its own tissues that it misinterprets as foreign, the complement system can also be activated. The amount or activity of complement proteins in the blood is measured by complement assays.

A component of the body's innate immune system is the complement system. The innate immune system is non-specific and rapid to react to external molecules, in contrast to the acquired immune system, which generates antibodies that target and defend against specific threats. It does not require prior exposure to an invasive drug or bacterium and does not keep track of prior interactions.

The primary complement proteins are numbered C1 through C9. There are nine of them. Together with the remaining proteins, these elements form complexes that react to infections, non-self tissues, dead cells, and inflammation by activating, amplifying, breaking apart, and generating cascades.

There are numerous strategies to start complement activation. These are known as lectin, alternative, or classical routes. However, the development of the membrane attack complex is the common result of all activation mechanisms. Several things happen as a result of complement activation:

  • Each pathogen or aberrant cell that has been selected for eradication adheres to the surface thanks to the MAC. It produces lysis, or the demise of the cell by letting the contents out, much like puncturing a water-filled balloon, by creating a lesion in the membrane wall.
  • It makes blood arteries more permeable, enabling white blood cells to go from the bloodstream and into the tissues to fight infections.
  • WBCs are drawn to the infection site by it.
  • It promotes the killing of germs by macrophages and neutrophils during phagocytosis, a process.
  • It makes immune complexes more soluble and aids in their removal from the circulation.

The amount or activity of complement proteins in the blood is measured by complement assays. To ascertain whether the system is operating normally, complement components might be examined individually or collectively. The two complement proteins that are most routinely tested are C3 and C4. If a medical professional suspects a shortfall that cannot be detected by C3 or C4, total complement activity can be assessed. The function of the entire C1–C9 classical complement pathway is evaluated by CH50. Each of the nine complement levels can be measured separately to check for inherited or acquired deficits if this reading is outside the usual range.

Lab tests often ordered with a Complement Component C3c test:

  • Complement Component C4c
  • CH50
  • Sed Rate
  • C-Reactive Protein
  • Rheumatoid Factor
  • ANA Screen
  • Antibody Screen

Conditions where a Complement Component C3c test is recommended:

  • Autoimmune Disorders
  • Lupus
  • Rheumatoid Arthritis
  • Kidney disease
  • Vasculitis

How does my health care provider use a Complement Component C3c test?

To ascertain whether shortages or anomalies in the complement system are the root cause of, or contribute to, a person's sickness or condition, complement assays, most frequently C3 and C4, are utilized.

What do my Complement Component C3c test results mean?

Increased consumption or, less frequently, a congenital deficit, can cause complement levels to drop. A high incidence of recurrent microbial infections is typically caused by a hereditary defect in one of the complement proteins. Reduced complement levels are linked to a higher risk of autoimmune disease development. While C3 alone is often low in septicemia and diseases brought on by fungus or parasites, like malaria, C3 and C4 levels are typically both decreased in SLE.

Complement levels will typically return to normal if the underlying acute or chronic ailment can be treated if the deficiency is brought on by one of these.

Complement activity may be reduced with:

  • Hepatitis
  • Cirrhosis
  • Malnutrition
  • Septicemia
  • Kidney Disease
  • Lupus
  • Angioedema
  • Rheumatoid Arthritis

During acute or chronic inflammation, complement protein levels typically rise together with those of other unrelated proteins known as acute phase reactants. When the underlying illness is treated, all of these often return to normal. Comparatively to the frequently ordered C-reactive protein, complement proteins are less frequently measured in these circumstances, hence the value of their measurement in these circumstances is not discussed here.

Increased complement activity include can be seen with:

  • Juvenile Rheumatoid Arthritis
  • Thyroiditis
  • Sarcoidosis
  • Cancer
  • Ulcerative Colitis
  • Acute Myocardial Infarction

How does my health care provider use a Complement Total test?

When a person has a disease or illness, complement tests are done to evaluate whether deficiencies or abnormalities in the complement system are the root cause or a contributing factor. In order to assess the overall integrity of the classical complement pathway, total complement activity may be ordered. To check for deficits, additional complement components are obtained if necessary.

What do my Complement Total test results mean?

It's possible for complement levels to drop as a result of greater intake or, less frequently, a congenital deficiency. A high incidence of recurrent microbial infections is typically caused by a hereditary defect in one of the complement proteins. Reduced complement levels are linked to a higher risk of autoimmune disease development.

Complement levels will typically return to normal if the underlying acute or chronic ailment can be treated if the deficiency is brought on by one of these.

During acute or chronic inflammation, complement protein levels typically rise together with those of other unrelated proteins known as acute phase reactants.

Testing for anti-neutrophil cytoplasmic antibodies (P-ANCA and/or C-ANCA) has been found to be useful in establishing the diagnosis of suspected vascular diseases (e.g., crescentic glomerulonephritis, microscopic polyarteritis and Churg-Strauss syndrome), bowel disease (Crohn's Disease, ulcerative colitis, primary sclerosing cholangitis, and autoimmune hepatitis) as well as with other autoimmune diseases (drug-induced lupus, SLE, Felty's syndrome). ANCA has classically been divided into C-ANCA and P-ANCA depending on the immunofluorescent pattern observed. More recently the specific antigens responsible for these patterns have been described and isolated. The antigen that gives the C-ANCA pattern is proteinase-3 (PR-3). Multiple antigens are responsible for P-ANCA pattern, the principle antigen being myeloperoxidase (MPO). Patients with vascular diseases will generally have either a C-ANCA pattern or P-ANCA pattern, and give positive results in specific tests for PR-3 or MPO. Patients with bowel disease have been shown to have antibodies that give a P-ANCA or C-ANCA pattern. These antibodies however, may not be directed towards MPO. Patients with drug induced lupus, etc., often present with a P-ANCA pattern that is associated with antibodies against MPO.

Description: An antinuclear antibody screening is a blood test that is going to look for a positive or negative result. If the result comes back as positive further test will be done to look for ANA Titer and Pattern. Antinuclear antibodies are associated with Lupus.

When is a Comprehensive ANA IFA Panel test ordered?

When someone exhibits signs and symptoms of a systemic autoimmune illness, the ANA test is requested. Symptoms of autoimmune illnesses can be vague and non-specific, and they can fluctuate over time, steadily deteriorate, or oscillate between periods of flare-ups and remissions.

What does a Comprehensive ANA IFA Panel blood test check for?

Antinuclear antibodies are a type of antibody produced by the immune system when it is unable to differentiate between its own cells and foreign cells. Autoantibodies are antibodies that attack the body's own healthy cells, causing symptoms like tissue and organ inflammation, joint and muscle discomfort, and weariness. The moniker "antinuclear" comes from the fact that ANA specifically targets chemicals located in a cell's nucleus. The presence of these autoantibodies in the blood is detected by the ANA test.

The presence of ANA may be a sign of an autoimmune process, and it has been linked to a variety of autoimmune illnesses, the most common of which being systemic lupus erythematosus.

One of the most common tests used to detect an autoimmune disorder or rule out other conditions with comparable signs and symptoms is the ANA test. As a result, it's frequently followed by other autoantibody tests that can help establish a diagnosis. An ENA panel, anti-dsDNA, anti-centromere, and/or anti-histone test are examples of these.

Lab tests often ordered with a Comprehensive ANA IFA Panel test:

The antinuclear antibody test is one of the most common tests used to identify systemic lupus erythematosus. It is used as a primary test to assist evaluate a person for autoimmune illnesses that affect multiple tissues and organs throughout the body.

When a person's immune system fails to discriminate between their own cells and foreign cells, autoantibodies called ANA are created. They attack chemicals found in a cell's nucleus, causing organ and tissue damage.

ANA testing may be utilized in conjunction with or after other autoantibody tests, depending on a person's indications and symptoms and the suspected condition. Antibodies that target specific compounds within cell nuclei, such as anti-dsDNA, anti-centromere, anti-nucleolar, anti-histone, and anti-RNA antibodies, are detected by some of these tests, which are considered subsets of the general ANA test. In addition, an ENA panel can be utilized as a follow-up to an ANA.

These further tests are performed in addition to a person's clinical history to assist diagnose or rule out other autoimmune conditions such Sjögren syndrome, polymyositis, and scleroderma.

To detect ANA, various laboratories may employ different test procedures. Immunoassay and indirect fluorescent antibody are two typical approaches. The IFA is regarded as the gold standard. Some labs will test for ANA using immunoassay and then employ IFA to confirm positive or equivocal results.

An indirect fluorescent antibody is created by mixing a person's blood sample with cells attached to a slide. Autoantibodies in the blood bind to the cells and cause them to react. A fluorescent antibody reagent is used to treat the slide, which is then inspected under a microscope. The existence of fluorescence is observed, as well as the pattern of fluorescence.

Immunoassays—these procedures are frequently carried out using automated equipment, however they are less sensitive than IFA in identifying ANA.

Other laboratory tests linked to inflammation, such as the erythrocyte sedimentation rate and/or C-reactive protein, can be used to assess a person's risk of SLE or another autoimmune disease.

What do my ANA test results mean?

A positive ANA test indicates the presence of autoantibodies. This shows the presence of an autoimmune disease in someone who has signs and symptoms, but more testing is needed to make a definitive diagnosis.

Because ANA test results can be positive in persons who have no known autoimmune disease, they must be carefully assessed in conjunction with a person's indications and symptoms.

Because an ANA test can become positive before signs and symptoms of an autoimmune disease appear, determining the meaning of a positive ANA in a person who has no symptoms can take some time.

SLE is unlikely to be diagnosed with a negative ANA result. It is normally not required to repeat a negative ANA test right away; however, because autoimmune illnesses are episodic, it may be desirable to repeat the ANA test at a later date if symptoms persist.

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

When is an ANA Screen test ordered?

When someone exhibits signs and symptoms of a systemic autoimmune illness, the ANA test is requested. Symptoms of autoimmune illnesses can be vague and non-specific, and they can fluctuate over time, steadily deteriorate, or oscillate between periods of flare-ups and remissions.

What does an ANA Screen blood test check for?

Antinuclear antibodies are a type of antibody produced by the immune system when it is unable to differentiate between its own cells and foreign cells. Autoantibodies are antibodies that attack the body's own healthy cells, causing symptoms like tissue and organ inflammation, joint and muscle discomfort, and weariness. The moniker "antinuclear" comes from the fact that ANA specifically targets chemicals located in a cell's nucleus. The presence of these autoantibodies in the blood is detected by the ANA test.

The presence of ANA may be a sign of an autoimmune process, and it has been linked to a variety of autoimmune illnesses, the most common of which being systemic lupus erythematosus.

One of the most common tests used to detect an autoimmune disorder or rule out other conditions with comparable signs and symptoms is the ANA test. As a result, it's frequently followed by other autoantibody tests that can help establish a diagnosis. An ENA panel, anti-dsDNA, anti-centromere, and/or anti-histone test are examples of these.

Lab tests often ordered with an ANA Screen test:

  • ENA Panel
  • Sed Rate (ESR)
  • C-Reactive Protein
  • Complement
  • AMA

Testing for anti-neutrophil cytoplasmic antibodies (P-ANCA and/or C-ANCA) has been found to be useful in establishing the diagnosis of suspected vascular diseases, inflammatory bowel disease, as well as other autoimmune diseases.

Additional test processing fees will be charged if initial results dictate Reflex (further) testing.


Description: An ANCA screen is used to detect antineutrophil cytoplasmic antibodies in your blood to test for autoimmune vasculitis and to differentiate between Crohn’s disease and ulcerative colitis when testing for inflammatory bowel disease.

Also Known As: ANCA test, cANCA test, pANCA test, Serine Protease 3 test, Acticytoplasmic Test, 3-ANCA test, PR3-ANCA Test, MPO-ANCA test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is an ANCA Screen test ordered?

When a person exhibits symptoms and signs that point to systemic autoimmune vasculitis, an ANCA test must be performed. Early indications of the illness could include a fever, weariness, weight loss, aches in the muscles and/or joints, and nocturnal sweats. As the illness worsens, damage to blood arteries all throughout the body may result in the signs and symptoms of consequences affecting different tissues and organs.

When a patient exhibits symptoms that point to inflammatory bowel disease and the doctor wants to differentiate between Crohn's disease and ulcerative colitis, they may be prescribed an ANCA test together with an anti-Saccharomyces cerevisiae antibody test.

What does an ANCA Screen test check for?

The immune system of a person makes autoantibodies called antineutrophil cytoplasmic antibodies that wrongly target and attack proteins found in the person's neutrophils. These autoantibodies are found in the blood and their concentration is determined by ANCA testing. The autoantibodies that target the proteins myeloperoxidase and proteinase 3 are two of the most prevalent forms or subgroups of ANCA.

An individual's blood sample is combined with neutrophils for the test, which is then put on a slide and stained fluorescently. Under a microscope, ANCA will exhibit a pattern of fluorescence if they are present. Atypical ANCA, perinuclear, or cytoplasmic ANCA are possible classifications for the pattern. Alternately, a direct ELISA assay can be used in the laboratory to check for myeloperoxidase or proteinase 3 antibodies. When investigating possible vasculitis cases, fluorescence and ELISA testing are frequently combined.

ANCA may be found in a number of autoimmune conditions that result in organ failure, tissue damage, and inflammation.

Systemic vasculitis is a group of diseases characterized by blood vessel deterioration and injury. Due to blood channel narrowing and obstruction, which results in a reduction in blood supply, it can harm tissue and organs. Aneurysms, which are weak spots in the walls of blood vessels that have the potential to burst, can also be created. The degree of autoimmune activity and the areas of the body affected by systemic vasculitis determine the symptoms that an affected person may experience. There are a few forms of systemic vasculitis that are closely linked to ANCA production:

  • Polyangiitis and granulomatosis
  • Miniature polyangiitis
  • Polyangiitis along with eosinophilic granulomatosis
  • Nodular polyarteritis

The most typical cases of cANCA/PR3 antibodies and pANCA/MPO antibodies include granulomatosis with polyangiitis and microscopic polyangiitis, respectively. To varied degrees of responsiveness, both may be present in all three categories.

An instance of inflammatory bowel disease known as ulcerative colitis is characterized by inflamed and harmed tissues in the colon's lining. UC and Crohn disease, another kind of IBD that can affect any section of the intestinal tract, can be challenging to distinguish from one another. Atypical ANCA is typically seen in UC patients, but only 20% of CD patients may be positive.

Lab tests often ordered with an ANCA Screen test:

  • Antibody Panel
  • Complete Blood Count (CBC)
  • Sed Rate
  • C-Reactive Protein
  • Urinalysis
  • ASCA
  • Calprotectin
  • Lactoferrin

Conditions where an ANCA Screen test is recommended:

  • Autoimmune Disorders
  • Vasculitis
  • Inflammatory Bowel Disease

How does my health care provider use an ANCA Screen test?

ANCA antibody tests can be used to:

  • Assist in the detection and diagnosis of granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis, among other types of autoimmune vasculitis. This test may occasionally be performed to keep tabs on the patient's progress in therapy or to spot a relapse of certain illnesses.
  • Help distinguish between Crohn's disease and ulcerative colitis, two prevalent varieties of inflammatory bowel illness.

ANCA are immune system-generated autoantibodies that wrongly target proteins in a person's neutrophils. Myeloperoxidase and proteinase 3 are the targets of the majority of ANCA subgroups.

There are two possible exam types:

  • ANCA testing are most frequently carried out with indirect immunofluorescence microscopy. Neutrophils and serum samples are combined to allow any potential autoantibodies to interact with the cells. A fluorescent stain is applied to the sample before it is placed on a slide. After that, the slide is studied under a microscope to identify any patterns. MPO antibodies are linked to the perinuclear pattern, while PR3 antibodies are linked to the cytoplasmic pattern. Atypical ANCA is yet another potential pattern.
  • Antibodies to proteinase 3 and myeloperoxidase can be evaluated separately and specifically using an immunoassay technique.

ANCA, MPO, and PR3 are three tests that some labs will run as a panel, while others will only run MPO and PR3 if the initial ANCA test is positive.

Erythrocyte sedimentation rate and/or C-reactive protein tests to check for inflammation, complete blood counts to measure and assess white and red blood cells, and urinalysis, blood urea nitrogen, and creatinine tests to assess kidney function are additional tests that may be carried out to help with diagnosis. Viral tests for hepatitis or CMV may be prescribed for some patients.

What do my ANCA Screen test results mean?

Care must be taken while interpreting ANCA test results and many considerations must be made. A doctor will take into account clinical symptoms in addition to the outcomes of laboratory testing and other kinds of examinations, such imaging investigations.

Positive results from the ANCA, PR3, and/or MPO tests aid in confirming the diagnosis of systemic autoimmune vasculitis and identifying its many subtypes. However, a biopsy of an afflicted spot is frequently needed to confirm a diagnosis.

Results from negative ANCA tests indicate that an autoimmune vasculitis is not likely to be the cause of a person's symptoms.

Multiple ANCA patterns may be observed for a successful outcome using the indirect immunofluorescence microscopy method.

Perinuclear fluorescence is especially prominent close to the nucleus. In about 90% of samples MPO antibodies will be present with a pANCA pattern.

Fluorescence that is cytoplasmic spreads throughout the cell's cytoplasm. In about 85% of samples PR3 antibodies will be present with a cANCA pattern.

Very little or no fluorescence indicates negative ANCA.

If the ANCA test is positive, another test is run to figure out how much antibody is actually present. The term for this is titer. A serum sample is diluted in stages to determine the titer, and the presence of the antibody is checked after each dilution. The titer is the highest dilution at which the antibody can be found. The titer is 1:64, for instance, if a serum tests positive after being diluted 64 times. More antibody is found in the blood the greater the titer.

ANCA levels can fluctuate over time and are occasionally used in a broad sense to monitor disease activity and/or therapeutic response; nevertheless, titer levels may be variable in certain patients, inadequately reflecting the status of remission or relapse.

More than 80% of individuals with active granulomatosis with polyangiitis have a positive PR3 antibody test and a positive cANCA or pANCA.

Indicators of microscopic polyangitis, glomerulonephritis, eosinophilic granulomatosis with polyangiitis, and Goodpasture syndrome include positive tests for MPO antibodies and a positive pANCA. Other autoimmune diseases such systemic lupus erythematosus, rheumatoid arthritis, and Sjögren syndrome may also exhibit MPO and pANCA.

Patients with signs of an inflammatory bowel illness may benefit from ANCA testing.

If the atypical ANCA is positive and the ASCA is negative, ulcerative colitis is probably present.

As long as ASCA is positive and atypical ANCA is negative, Crohn's disease is most likely present. Even if ANCA and/or ASCA tests are negative, a person may nonetheless have UC, CD, or another IBD.

Cardiolipin antibodies (CA) are seen in a subgroup of patients with autoimmune disorders, particularly Systemic Lupus Erythematosus (SLE), who are at risk for vascular thrombosis, thrombocytopenia, cerebral infarct and/or recurrent spontaneous abortion. Elevations of CA associated with increased risk have also been seen in idiopathic thrombocytopenic purpura, rheumatoid and psoriatic arthritis, and primary Sjögren's syndrome.


Vasculitis is a term that is used to describe a group of conditions characterized by inflamed blood vessels. If there is not a clear, obvious cause for the condition, then it is typically referred to as primary vasculitis. When there is a cause, it is called secondary vasculitis. There are a lot of things that can cause secondary vasculitis, such as allergic reactions to medication, infection with hepatitis C, auto-immune diseases such as rheumatoid arthritis, and even complications related to lymphoma or leukemia. 

Vasculitis can affect veins, arteries, and capillaries, resulting in narrowed vessels that limit the circulation of blood and can cause tissue or organ damage. A weakened vessel can lead to an aneurysm, which may, in turn, cause life-threatening internal bleeding. 

There are a lot of different kinds of vasculitis, and they are classified based on the size and type of the blood vessel affected. Understanding the different types and they’re sometimes confusing or nebulous symptoms is important for recognizing the condition so that people can get appropriate treatment. 

The Types of Vasculitis and their Symptoms 

Vasculitis is a systemic illness. This means that symptoms can often be non-specific. Some of the most common symptoms are easily confused with other diseases that cause inflammation, for example: 

  • Loss of appetite 
  • Fatigue 
  • Weight loss 
  • Aches and pains 
  • Fever 

The symptoms might come on suddenly or could gradually surface over a period of several months. The order of onset, presentation, and type of symptoms can vary massively. Some people experience localized symptoms specific to the type of vasculitis that they are suffering from, and this can help to characterize the condition more clearly in some cases, but not everyone’s condition results in the same symptoms, so diagnosis is not easy. 

Laboratory Test

Complete Blood Count (CBC) testing is a test that checks the red blood cells and hemoglobin and can help to diagnose anemia. It also looks at the white blood cell count, which may be increased if someone has an infection, or reduced if they have had treatments that may weaken the immune system. Some types of vasculitis can cause increased white blood cell counts. One example is Eosinophilic Granulomatosis with Polyangiitis (EGPA). 

C-reactive protein (CRP) testing can identify cases of inflammation within the body. 

Erythrocyte sedimentation rate (ESR) testing is another test that can detect inflammation, and it can identify certain types of vasculitis,  with this test also detects the presence of inflammation and can be increased in several types of vasculitis, such as microscopic polyangiitis and granulomatosis with polyangiitis being one example. 

Creatinine testing is used to assess the functioning of the kidneys. Reduced kidney function is sometimes present in vasculitis. 

Liver panels help to determine if liver function is impaired. 

Urinalysis looks for red blood cells and protein in the urine, which can be a sign of kidney inflammation. 

Anti-neutrophil cytoplasmic antibody (ANCA) testing looks for a marker that can be often be found in patients with certain systemic vasculitis diseases. 

Complement is a test for the part of the immune response, which is something that is often reduced in people with vasculitis.
