Clinical Significance
Beta-2-Glycoprotein 1, apolipoprotein H, is a cofactor in antiphospholipid antibody binding and is the critical antigen in the antiphospholipid antibody syndrome. Beta-2- Glycoprotein 1 antibody is more specific than cardiolipin antibody that may express reactivity in patients with syphilis and other infectious diseases.
