ANCA Profile Test - Uses - Side Effects - Test Results
ANCA Profile Test is a blood test that evaluates ANCA IgG and ANCA IgA. ANCA stands for Anti Neutrophil Cytoplasmic Antibodies, which are proteins made by specific cells of the immune system called neutrophils. ANCA is mainly used to assess ANCA vasculitis, or it is used to detect certain autoimmune diseases or infections. ANCA Profile Test is used to monitor ANCA production in your body and monitor remission or relapse of ANCA vasculitis. ANCA Profile Test is not diagnostic, but it helps diagnose ANCA vasculitis or other autoimmune diseases. ANCA profile measures ANCA levels in serum. ANCA levels are often elevated during the active phase of the disease and drop after remission. ANCA profile should be performed together with C-reactive protein (CRP), ESR (sedimentation rate), and ANCA antibodies (IgG, IgM).

What is the ANCA profile?
ANCA stands for anti-neutrophil cytoplasmic antibodies. ANCA profile testing is a blood test to measure ANCA. ANCA Profile is a series of tests that can be performed to determine what is happening inside a patient’s body. ANA results are considered positive when ANCA levels are higher than 100 units per millimeter. This ANA profile helps doctors determine certain causes of inflammation and can help diagnose autoimmune diseases such as lupus.
What is the ANCA profile used for?
ANCA profile test is used to identify ANCA disease. ANCA stands for anti-neutrophil cytoplasmic antibodies, which are antibodies that recognize and attach themselves to proteins in the cell called neutrophils. The ANCA profile tests for specific types of ANCA antibodies that indicate an autoimmune reaction such as vasculitis. ANCA disease is an ANCA-positive test that can cause inflammation and damage blood vessels. ANCA profile tests can be used to monitor disease activity in patients with ANCA vasculitis.
Understanding the Test Results of ANCA Profile Test
The ANCA profile test is used for ANCA disease diagnosis. This test is performed to determine the presence of ANCA in blood samples. Increased ANCA levels can lead to ANCA-related diseases like Wegener’s Granulomatosis (WG) and Microscopic Polyangiitis (MPA). ANCA profile test is performed when ANCA-positive patients show symptoms that manifest through their eyes and kidneys. In such cases, the condition can be managed by treating ANCA.
Frequently Asked Questions:
Why do I need an ANCA profile Test?
ANCA profile test is the most important test to diagnose ANCA vasculitis. It is conducted with blood samples and reveals how active ANCA disease is. The test consists of 4 subgroups ANCA-A, ANCA-B, ANCA-C, and ANCA-P. ANCA-A and ANCA-B are neutrophil antibodies. ANCA-C is made up of antibodies against Myeloperoxidase (MPO), which is present in the lysosome granules of neutrophils. ANCA-P is a cytoplasmic ANCA antibody. It binds to proteinase 3 (PR3). The ANCA profile test is a sensitive and specific test. It reveals how active ANCA disease is, and it also shows if the kidneys or liver show signs of damage, which may lead to end-stage renal or end-stage liver disease, respectively. It helps determine the severity of ANCA vasculitis and ANCA disease.
What happens during an ANCA profile test?
ANCA profile test normally does not take more than 30 minutes, but it may occasionally take longer. The test is performed through the following steps:
- The patient's blood sample is taken for the test using a painless finger stick.
- The blood sample collected during the test will be poured into bottles for analysis. This is done automatically by machines used to do the test.
- ANCA Profile Report is generated by a machine, and a copy of the test results is given to the doctor for further analysis.
What is ANCA disease?
ANCA disease or ANCA vasculitis is a type of systemic vasculitis, an inflammatory disease that occurs when blood vessels become inflamed. ANCA Vasculitis is a type of AN CA, which is used to diagnose ANCA vasculitis. The disease occurs when ANCA is produced in the body. ANCA forms part of the immune system and is designed to fight bacteria, but it may mistakenly attack the cells lining blood vessels (the endothelium).
What can cause a positive ANCA test?
ANCA vasculitis can be caused by an infection (such as strep throat), cancer (such as leukaemia or lymphoma), certain medications, or autoimmune diseases. ANCA profile test is used to help diagnose ANCA vasculitis. It measures levels of ANCA in the blood. It is known as the ANCA titer test. The test is most useful when ANCA vasculitis symptoms are present, and the ANCA profile test results will be compared to the patient’s ANCA levels before treatment.
Can you live a long life with ANCA vasculitis?
Yes, ANCA vasculitis is one of the under-diagnosed autoimmune diseases, which can lead to organ damage in severe conditions if not diagnosed in time. ANCA vasculitis is considered a manageable disease with ANCA medication. It can also lead to cancer, so it should be treated as soon as possible by ANCA profile test. ANCA vasculitis patients are advised to undergo a routine checkup of their eyes and kidneys.
What is a normal ANCA level?
The normal ANCA level may differ from one lab to another. ANCA profile test is performed using ANCA Enzyme-Linked Immunosorbent Assay (ELISA). The normal value of ELISA is 0.00 - 0.22 units/ml.
Can ANCA be positive for a healthy person?
Yes, ANCA can be positive for a healthy person too. ANCA is detected using ANCA enzyme-linked immunosorbent assay (ELISA). ANCA test results will show the levels of ANCA if it is present in the blood sample.
Do I need to fast for the ANCA test?
No, you do not need to fast for the ANCA test. ANCA profile test uses a painless finger stick to obtain a small drop of blood, which is used for analysis. It involves two ANCA tests, P-ANCA and A-ANCA, that must be performed together.
