Antiphospholipid antibodies (APA) are associated with an increased risk of venous and arterial thrombosis and recurrent fetal loss.These antibodies can be IgG, IgM, or IgA.

Antiphospholipid antibodies require several different tests for detection. Lupus anticoagulants are detected by clotting methods. APA such as anticardiolipin antibody and anti-beta 2 glycoprotein 1 antibodies are detected by immunologic assays. Anti-Beta 2 Glycoprotein Antibodies are a more specific marker for increased risk of thrombosis than anticardiolipin assays. APA associated with thrombotic risk are persistent, and should be confirmed by a repeat positive test after 2-3 months. APA results aid in diagnosis and are helpful in determining the intensity and duration of anticoagulant treatment for patients with Antiphospholipid Syndrome and thrombosis.
