Anca Test

The ANCA test, which stands for Antineutrophil Cytoplasmic Antibodies test, is a blood test used to detect the presence of specific antibodies in the bloodstream. These antibodies are associated with autoimmune diseases, particularly those affecting the blood vessels and causing inflammation.

The ANCA test is performed to help diagnose and monitor autoimmune diseases, such as granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). It can also aid in distinguishing between different types of vasculitis.

A blood sample is collected from a vein in your arm, and the serum is separated to measure the presence of ANCA antibodies. The test is typically performed in a clinical laboratory.

ANCA test results are usually available within a few days to a week, depending on the laboratory's processing time. Your healthcare provider will discuss the results and their implications with you.
