Anti-Beta-2-Glycoprotein IgM Test - Anti-Beta-2-Glycoprotein I Antibodies (IgM)

The anti-beta-2-glycoprotein I (IgM) antibody test is a quantitative immunoassay that detects and measures the concentration of immunoglobulin M (IgM) antibodies directed against beta-2-glycoprotein I in serum. The presence of these antibodies is a diagnostic laboratory criterion for antiphospholipid syndrome.
