IgG and/or IgM...
IgG and/or IgM antibodies to phosphatidylserine (aPS) may be associated with a positive test for anti-cardiolipin autoantibodies (aCL) and risk for obstetric antiphospholipid syndrome (APS)
Strong clinical correlation is recommended in the absence of lupus anticoagulant, IgG and/or
IgM cardiolipin and/or beta2 glycoprotein antibodies

Isolated presence of IgM or IgG antibodies to aPS may have questionable clinical significance for APS and/or SLE

If results are positive, repeat testing with two or more specimens drawn at least 12 weeks apart to demonstrate persistence of antibodies

Results should not be used alone for diagnosis and must be interpreted in light of APS-specific clinical manifestations and/or other criteria phospholipid antibody tests
