Special Info

3.2% Sodium citrate is the preferred anticoagulant recommended by CLIS. Indicate if patient is receiving heparing or direct thrombin inhibitor, as these anti-thrombotic drugs can interfere with the assay results.

Clinical Info

Confirmatory assay to detect the presence of a lupus anticoagulant. This test should not be used alone in the diagnosis of a lupus anticoagulant, as many factors, such as anticoagulant therapy, can interfere with this assay. It is also suggested that a circulating anticoagulant, a platelet neutralization and dRVVT be ordered in the evaluation of a lupus anticoagulant. A lupus panel, which includes these tests plus an interpretation, is available. Thrombin inhibitors will interfere and may give falsely positive results.
