Beta 2 Glycoprotein 1 IgG Serum

Beta 2 Glycoprotein 1 IgG serum test detects the presence of beta-2 glycoprotein antibody in the blood. Also known as antiphospholipid antibodies, these antibodies are known to target the body’s own phospholipids (lipid proteins) and platelets. This test is mainly used to identify the cause of thrombosis (unexplained blood clot), recurrent miscarriages, and antiphospholipid syndrome (APS). It is mainly ordered along with other tests such as cardiolipin antibody and lupus anticoagulant.

The test is ordered if you have any signs and symptoms of excessive clotting or APS such as deep vein thrombosis (DVT), stroke or transient ischemic attacks (TIA), or pregnancy complications like preeclampsia or recurrent miscarriages. In some cases, people with lupus may also be advised this test to check these autoantibodies in blood.
