β2-Glycoprotein 1 Antibodies, IgG
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
Not provided.
Limitations
Anti-β2-Glycoprotein 1 should not be used alone as a screening test for antiphospholipid syndrome. While anti-β2-GP1 assays may be more specific for APS than ACA, approximately 30% of patients tested for both will have discordant results, and anti-β2-GP1 can be useful in evaluating patients with positive ACA results not consistent with APS.
