This test assists in the diagnosis of antiphospholipid syndrome (APS) and is applicable when APS is strongly suspected. The persistent presence of IgG and/or IgM cardiolipin antibodies in moderate or high levels (greater than 40 GPL and/or MPL units) is a laboratory criterion for APS diagnosis. Persistence is defined as detection in two or more specimens drawn at least 12 weeks apart. Lower positive levels may occur in patients with APS symptoms, but their significance is undefined. Results should be interpreted in conjunction with APS clinical manifestations and other phospholipid antibody tests.
