β2-Glycoprotein 1 Antibodies, IgA
Also known as: Anti-β2 Glycoprotein 1, Beta-2 Glycoprotein 1 Antibodies
Use
Assess the risk of thrombosis in patients who may be at risk for antiphospholipid syndrome (APS). This test should be used in conjunction with current traditional anticardiolipin and anticoagulant tests.1
Special Instructions
Anti-β2-glycoprotein 1 testing should be used in conjunction with traditional anticardiolipin and anticoagulant tests. It is not a standalone screening test for APS.
Limitations
Anti-β2-glycoprotein 1 should not be used alone as a screening test for antiphospholipid syndrome. Approximately 30% of patients tested will have discordant results between ACA and β2-GP1 antibodies. A negative anti-β2-GP1 result does not rule out APS in patients with positive ACA results.
