Cardiolipin Antibodies –IgG

Cardiolipin antibodies are autoantibodies produced by the immune system that mistakenly target the body's own cardiolipins, substances found in the outermost layer of cells (cell membranes) and platelets. These autoantibodies can affect the body's ability to regulate blood clotting in a way that is not well understood.

Anticardiolipin antibodies (ACA) are present in acquired prothrombotic syndromes and are linked to ischemic stroke, myocardial infarction, and systemic lupus erythematosus, but it is not known if they are causal or merely a sign of ongoing vascular inflammatory disease.
