   How does an ANCA blood test detect antineutrophil cytoplasmic antibodies?

   • The ANCA blood test detects the presence or absence of these autoantibodies by looking at the pattern of fluorescence on a slide under the microscope. Antineutrophil cytoplasmic antibodies may be present in a variety of autoimmune disorders that cause inflammation and damage to blood vessels throughout the body (systemic vasculitis).

   What does a negative ANCA test mean?

   • A negative result means that no ANCAs were found in your blood sample. Your symptoms probably aren't caused by autoimmune vasculitis. A positive result means that ANCAs were found in your blood sample. This may mean you have autoimmune vasculitis. Your test results will also show which type of ANCAs were found.

   What happens if ANCA antibodies are found?

   • If ANCA antibodies are found, another test may be done on your blood sample to see how much ANCA is in your blood. You will often need other blood tests and a biopsy to confirm the diagnosis. A biopsy is a procedure that removes a small sample of tissue or cells for testing.
