   What is ANCA testing?

   • ANCA testing is more commonly used to diagnose vasculitis, a group of autoimmune disorders that affect small blood vessels. In vasculitis, ANCAs attach to neutrophils and cause them to attack the blood vessels. This attack makes the blood vessels swell up. Three types of vasculitis are linked to ANCA:

   What does a positive ANCA test mean?

   • You may have both types of ANCA. If you are having symptoms of IBD, a positive result may mean that you are more likely to have ulcerative colitis rather than Crohn's disease. Up to 80% of the people with ulcerative colitis will have a positive ANCA test. Your doctor will explain the meaning of your test results to you.

   What are the different types of ANCA tests?

   • There are two main types of ANCA, and testing can determine whether you have one or both: cANCA: Targets a protein called proteinase 3 (PR3). pANCA: Targets a protein called myeloperoxidase (MPO). Who performs an ANCA test? A healthcare provider, like a nurse, doctor or laboratory technician, takes the sample of blood.

   Should ANCA be used to diagnose AAV?

   • In an appropriate clinical context, a positive ANCA test with proven specificity to either PR3 or MPO is strongly suggestive of AAV. In practice, ANCA should be used to support AAV diagnosis and suspected relapses.
