Antiphospholipid antibodies are directed against phospholipid-protein complexes and include lupus anticoagulant, anticardiolipin antibodies, and anti-beta-2 glycoprotein I antibodies. Antiphospholipid antibody syndrome is a common cause of acquired thrombophilia and is characterized by venous or arterial thromboembolism or pregnancy morbidity and the presence of antiphospholipid antibodies. Antibodies should be demonstrable on at least 2 occasions separated by 12 weeks. Heterogeneity of the autoantibodies and absence of gold standard assays makes interpretation of laboratory results a challenge for both laboratorians and clinicians. This review discusses the key laboratory and clinical aspects of antiphospholipid antibody syndrome. Particular focus is given to lupus anticoagulant detection, in view of recently updated laboratory guidelines.

UI	MeSH Term	Description	Entries
D006493	Heparin	A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.

D000305	Adrenal Cortex Hormones	HORMONES produced by the ADRENAL CORTEX, including both steroid and peptide hormones. The major hormones produced are HYDROCORTISONE and ALDOSTERONE.

D013923	Thromboembolism	Obstruction of a blood vessel (embolism) by a blood clot (THROMBUS) in the blood stream.	Thromboembolisms
D016682	Lupus Coagulation Inhibitor	An antiphospholipid antibody found in association with a variety of diseases (e.g., SYSTEMIC LUPUS ERYTHEMATOSUS and ANTIPHOSPHOLIPID SYNDROME) as well as in healthy individuals. In vitro, the antibody interferes with the conversion of prothrombin to thrombin and prolongs the partial thromboplastin time. In vivo, it exerts a procoagulant effect resulting in thrombosis mainly in the larger veins and arteries. It further causes obstetrical complications, including fetal death and spontaneous abortion, as well as a variety of hematologic and neurologic complications.

D016736	Antiphospholipid Syndrome	The presence of antibodies directed against phospholipids (ANTIBODIES, ANTIPHOSPHOLIPID). The condition is associated with a variety of diseases, notably systemic lupus erythematosus and other connective tissue diseases, thrombopenia, and arterial or venous thromboses. In pregnancy it can cause abortion. Of the phospholipids, the cardiolipins show markedly elevated levels of anticardiolipin antibodies (ANTIBODIES, ANTICARDIOLIPIN). Present also are high levels of lupus anticoagulant (LUPUS COAGULATION INHIBITOR).

D017152	Antibodies, Antiphospholipid	Autoantibodies directed against phospholipids. These antibodies are characteristically found in patients with certain autoimmune diseases (e.g., SYSTEMIC LUPUS ERYTHEMATOSUS and ANTIPHOSPHOLIPID SYNDROME), some non-autoimmune diseases, and also in healthy individuals.

D017153	Antibodies, Anticardiolipin	Antiphospholipid antibodies found in association with systemic lupus erythematosus (LUPUS ERYTHEMATOSUS, SYSTEMIC;), ANTIPHOSPHOLIPID SYNDROME; and in a variety of other diseases as well as in healthy individuals. The antibodies are detected by solid-phase IMMUNOASSAY employing the purified phospholipid antigen CARDIOLIPIN.
