Clinical significance: |
The Antiphospholipid Antibody Syndrome (APS) is a clinical-pathologic correlation that includes a clinical event (e.g., thrombosis, pregnancy loss, thrombocytopenia) and persistent positive Antiphospholipid Antibodies (IgM or IgG ACA >40 MPL/GPL, IgM or IgG anti-B2GPI antibodies, or a Lupus Anticoagulant). The IgA isotype has been implicated in smaller studies, but has not yet been incorporated into the APS criteria. International consensus guidelines suggest waiting at least 12 weeks before retesting to confirm antibody persistence. Reference J Thromb Haemost 2006: 4; 295. |
