This test detects IgM antibodies directed against Beta-2 Glycoprotein 1 (β2GPI), part of the antibody group linked to Antiphospholipid Syndrome (APS).

Diagnostic Value: Anti-β2GPI IgM may appear earlier in disease development than IgG and can help identify autoimmune activity in patients with unexplained clotting or pregnancy loss.

Clinical Significance: Elevated IgM β2GPI antibodies may contribute to thrombotic events such as deep vein thrombosis or arterial clots. Persistent positivity suggests an ongoing autoimmune process.

Symptom Correlation: Patients with IgM β2GPI antibodies may experience leg pain, swelling, or pregnancy complications due to impaired circulation.

When interpreted with IgG and IgA results, the Beta-2 Glycoprotein 1 IgM test provides a comprehensive view of a patient’s autoimmune clotting risk profile.
