Anti-beta-2-glycoproteins (anti-B2GP1 antibodies, anti-beta-2-glycoprotein antibodies) are antibodies produced by an individual’s immune system against his or her own phospholipids. These phospholipids are found on the surface of the platelets responsible for blood clotting (clot formation). Antibeta-2-glycoproteins (anti-B2GP1 antibodies, anti-beta-2-glycoprotein antibodies) are often . In autoimmune disease, anti-apolipoprotein H (AAHA) antibodies, also called anti-β 2 glycoprotein I antibodies, comprise a subset of anti-cardiolipin antibodies and lupus anticoagulant.These antibodies are involved in sclerosis and are strongly associated with thrombotic forms of lupus. As a result AAHA are strongly implicated in autoimmune deep vein thrombosis.. Beta 2 Glycoprotein (IgG and IgM) General information Anti-phospholipid syndrome (APS) is an acquired autoimmune condition. The clinical features are venous, arterial and microvascular thrombosis and/or pregnancy complications. Testing for β2GP1 antibodies can.
