Test includes:
Cardiolipin Antibody IgG, Cardiolipin Antibody IgM, Cardiolipin Antibody IgA
Enzyme-Linked Immunosorbent Assay (ELISA)
Anticardiolipin antibody panel
Antiphospholipid antibody panel
Antiphospholipid AB
ACA antibody panel, ACL antibody panel
Cardiolipin antibody
Clinical significance:
The presence of cardiolipin antibodies when used in conjunction with clinical findings and other laboratory tests can aid in assessing the risk of thromboembolic disease in patients with systemic lupus erythematosus (SLE) or primary anti-phospholipid syndrome (APS).
