The test is for the semi-quantitative combined detection of IgG, IgM and IgA autoantibodies specific for the Phospholipid Cardiolipin in huma serum or plasma (EDTA, citrate, heparin). The kit is intended to assess total anti-Cardiolipin autoantibody levels in patients where this information is useful in diagnosis, particularly as an aid in the assessment of thrombotic risk in patients with systemic lupus erythematosus or other lupus like disorders. Total anti-Cardiolipin levels represent one parameter in a multi-criterion diagnostic process.

§ 866.5660 Multiple autoantibodies immunological test system.
(a)
Identification. A multiple autoantibodies immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoantibodies (antibodies produced against the body's own tissues) in serum and other body fluids. Measurement of multiple autoantibodies aids in the diagnosis of autoimmune disorders (disease produced when the body's own tissues are injured by autoantibodies).(b)
Classification. Class II (performance standards).
