The C-ANCA PR3 test measures the presence of anti-proteinase 3 (PR3) antibodies in the blood. These antibodies target PR3, an enzyme found in neutrophils, and are associated with certain autoimmune diseases, particularly vasculitis conditions like Wegener's granulomatosis and microscopic polyangiitis. The test helps diagnose these conditions by detecting these specific antibodies, indicating immune system activity against the body’s own tissues. It also aids in monitoring disease activity and treatment effectiveness.

The C-ANCA PR3 test is a diagnostic blood test that detects the presence of anti-proteinase 3 (PR3) antibodies. These antibodies target PR3, an enzyme found in neutrophils, and are specifically associated with certain autoimmune diseases, notably vasculitis conditions like Wegener's granulomatosis (now known as granulomatosis with polyangiitis) and microscopic polyangiitis.

In autoimmune vasculitis, the immune system erroneously attacks the body’s own blood vessels, leading to inflammation and damage. The presence of C-ANCA (cytoplasmic antineutrophil cytoplasmic antibodies) that target PR3 is a marker of this aberrant immune response.

The C-ANCA PR3 test is used to diagnose these diseases by confirming the presence of these specific antibodies. It also helps in monitoring disease activity and response to treatment. Elevated levels of C-ANCA PR3 can indicate active disease or a relapse, guiding therapeutic decisions. However, it is used alongside clinical evaluation and other diagnostic tests to provide a comprehensive view of the patient's condition.
