Lupus anticoagulants are antibodies that recognize phospholipids on the platelet surface. Lupus anticoagulants interfere with phospholipids in phospholipid-dependent tests like the aPTT and dRVVT, thereby prolonging the clotting time. A lupus anticoagulant panel is positive if 1) two phospholipid-dependent tests show a prolonged clotting time; 2) the clotting time does not correct with a mixing study; and 3) the clotting time corrects in the presence of excess phospholipids.
