7 results for "Antinuclear Antibodies (ANA)" between $25.00 and $300.00

The body's immune system normally attacks invaders such as bacteria and viruses. An ANA test measures antibodies in your blood that attack your body's healthy tissues (autoimmune diseases). While low levels of ANA are common in Rheumatoid Arthritis, high levels of ANA may indicate possible Lupus.

This test detects antibodies to nuclear antigens. The ANA test is ordered to help screen for autoimmune disorders such as rheumatoid arthritis, scleroderma and Sjögren’s syndrome. It is most often used as one of the tests to diagnose systemic lupus erythematosus (SLE).

Antineutrophil cytoplasmic autoantibodies exhibiting pANCA or cANCA patterns are detected using indirect immunofluorescent antibody (IFA) techniques with a substrate of ethanol-fixed human neutrophils. Positive patient sera with perinuclear or nuclear patterns are repeated using a formalin-fixed substrate in order to differentiate the presence of true pANCA antibodies from possible interference with antinuclear antibodies (ANA).

Detect antibodies associated with SLE and mixed connective tissue disease. Anti-Sm is highly specific for SLE. Anti-RNP is found with a variety of rheumatoid diseases. RNP, Sm, SS-A, SS-B, Scl-70, and Jo-1 are extractable nucleoprotein complexes found in the nucleus and/or cytoplasm of substrate cells.
