ANA Screen w/ Reflex to Components

ANA Screen w/ Reflex to Components is a comprehensive blood test that includes the presence of antinuclear antibodies (ANAs), which are autoantibodies targeting the cell nucleus. A positive ANA screen suggests potential autoimmune activity which will then prompt a reflex to the 11 ANA Components test for 11 specific autoantibodies against distinct nuclear antigens, helping to identify or differentiate particular autoimmune diseases.
