The Complement Total CH50 Test measures overall activity of the complement system, a key part of the immune response that helps fight infections and regulate inflammation. Abnormal results may indicate autoimmune diseases such as lupus, complement deficiencies, or immune complex disorders. Doctors use this blood test to evaluate immune function, investigate recurrent infections, and monitor treatment in patients with suspected immune or autoimmune conditions.

The ANCA Vasculitides Test measures antibodies that target neutrophils, helping identify autoimmune vasculitis. It aids in diagnosing conditions including granulomatosis with polyangiitis and microscopic polyangiitis. This test provides insight into systemic inflammation, kidney disease, and respiratory involvement, supporting evaluation of autoimmune disorders linked to vascular and organ damage.

The ANA IFA Panel Comprehensive screens for autoimmune disorders by detecting antinuclear antibodies and specific markers including dsDNA, Sm, Sm/RNP, Scl-70, and Sjögren’s SS-A/SS-B. Doctors order this panel for patients with joint pain, rash, fatigue, or suspected lupus, scleroderma, or Sjögren’s syndrome. Results provide critical insight into autoimmune activity, helping confirm diagnosis, monitor disease progression, and guide treatment decisions.

The ANA Screen IFA with Reflex to Titer and Pattern Test detects antinuclear antibodies in blood to evaluate autoimmune activity. If positive, further testing identifies antibody concentration (titer) and fluorescence pattern, helping diagnose conditions like lupus, rheumatoid arthritis, or Sjögren’s syndrome. Doctors order this test to investigate symptoms such as joint pain, fatigue, rash, or swelling and to guide treatment for autoimmune and connective tissue disorders.

The ANCA Screen with MPO and PR3 with Reflex to ANCA Titer detects antineutrophil cytoplasmic antibodies linked to autoimmune vasculitis.
