The Purpose of an Anticardiolipin Antibodies Blood Test

Anticardiolipin antibodies are autoantibodies that interfere with normal blood clotting. People with abnormal levels of these autoantibodies, which are produced by the immune system, can be at increased risk for stroke, myocardial infarction, venous thrombosis, thromboembolism, thrombocytopenia, and/or recurrent miscarriages. This condition is referred to as antiphospholipid syndrome (APS).
