The Cardiolipin antibody (IgG) test (GenBio) is an ELISA for the quantitative detection of autoimmune antibodies to cardiolipin (aCL), a subset of antiphospholipid antibodies. This assay includes standardized cofactor beta 2 glycoprotein (b2-GP1) and phosphotydyl serine to assure measurement of both anti-cardiolipin and anti-b2-GP1 activity.
Elevated levels of anti-cardiolipin have been associated with thrombosis in patients with "anti-phospholipid syndrome" and systemic lupus erythematosus (SLE).
