Clinical Significance

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 toward MPO. Patients with drug induced lupus, etc., often present with a P-ANCA pattern that is associated with antibodies against MPO.
