Test Usage

The antiphospholipid syndrome (APS) is a disorder of recurrent vascular thrombosis associated with persistently positive anticardiolipin (aCL) or lupus anticoagulant tests. In patients with APS, anticardiolipin antibodies bind a variety of charged phospholipids, including phosphatidylethanolamine, as well as they do cardiolipin. Lupus patients also have high titers of autoantibodies to various phospholipids, including phosphatidylethanolamine.
