The ANA-8-Screen ELISA is a test system for the qualitative measurement of antinuclear antibodies (ANAs) SS-A (52 and 60 kDa), SS-B, RNP-70, Sm, RNP/Sm, Scl-70, Centromere B and Jo-1 in human serum or plasma. This test is used for screening patients with suspected autoimmune connective tissue diseases, e.g. systemic lupus erythematosus, mixed connective tissue disease, Sjoegren’s syndrome, scleroderma, and polymyositis/dermatomyositis.
