Clinical Significance
Preferred second-line testing for strong suspicion of seronegative antiphospholipid syndrome (APS). Order incrementally or concurrently with other non-criteria antiphospholipid antibody tests. Cardiolipin antibody IgG and IgM panel is preferred (CAGM2).
When a normal anti-cardiolipin antibody level is found in the presence of clinical manifestations, the lupus anticoagulant test should be performed. Patients with current or prior syphilis infections may have an elevated result without increased risk of thrombosis. Anti-cardiolipin antibodies can appear transiently at low levels during many infections. If a patient's result is increased while there are clinical signs of infection, the test should be repeated after an interval of six months.
