Beta-2-Glycoprotein 1 IgG/IgM test is an ELISA (Enzyme-linked immune sorbent assay) test that pits

the IgG and IgM antibodies to fight against the beta-2-glycoprotein, present in serum

and Plasma. Normal: β2 GPI IgG ≤ 20 SGU U/mL. β2 GPI IgM ≤ 20 SMU U/mL.These results

suggest that levels of complexed beta 2 GPI are increased in patients with aPAs, perhaps as a result

of immune complex formation, or altered binding to other plasma constituents.
