Test Update: Beta-2 Glycoprotein 1 Antibodies

Effective November 5th, testing for Beta-2 Glycoprotein 1 antibodies (IgG and IgM, serum) will change from a reference send out test to Mayo Medical Laboratories to an in-house test available at Spectrum Health Laboratories.  This testing is useful for evaluation of patients of suspected antiphospholipid antibody syndrome.

In addition, a new Antiphospholipid Antibody Syndrome Panel will be added which allows for appropriate and complete testing for antiphospholipid antibody syndrome. This panel includes:

Lupus Screen

Cardiolipin IgG and IgM Antibodies

Beta-2 Glycoprotein 1 IgG and IgM Antibodies

This testing panel is consistent with recommendations from the revised Sapporo classification criteria.
