Clinical Information

Cardiolipin IgG/IgM and Beta Glycoprotein 1 IgG/IgM Antibodies when used in conjunction with other clinical findings, aid in the diagnosis of primary Antiphospholipid Syndrome (APS) and those secondary to systemic lupus erythematosus (SLE) or SLE-like disorders. Antibody profiles are encouraged to identify thrombotic risk and may be more useful than individual tests in identifying a patient's risk.
