Learn more about detecting and diagnosing autoimmune disorders, including common lupus symptoms and other related diseases. We offer a variety of advanced lab tests including our patented AVISE Lupus test.

AVISE CTD combines AVISE Lupus, a 10-marker diagnostic test designed to help rule-in or rule-out lupus, with an expanded connective tissue disease panel to aid in the differential diagnosis of other connective tissue diseases.

The AVISE CTD lupus test can help diagnose lupus as well as connective tissue diseases, myopathies, rheumatoid arthritis, autoimmune thyroid disease, and antiphospholipid syndrome, which sometimes coexist with lupus. AVISE CTD can also help patients with fibromyalgia determine whether an autoimmune disease is present alongside their fibromyalgia.

AVISE testing provides state-of-the-art insight to aid physicians in the diagnosis, prognosis and monitoring of autoimmune conditions.
