LUPUS ANTICOAGULANT ASSAYS  
The lupus anticoagulant profile and anticardiolipin antibody IgG and IgM assays are definitive for antiphospholipid syndrome and should be ordered together whenever the presence of a lupus anticoagulant is suspected.

Select each for further assay information:



The PT, PTT and mixing studies listed below may be useful screens for lupus anticoagulant but are not as sensitive as the lupus anticoagulant profile or the ACA. Lupus anticoagulant testing is a complex series of assays including the PTT-LA, Sta-Clot LA, and DRVVT assays which are not separately listed in our test menu.

For further information on the lupus anticoagulant testing protocol, go to Thrombophilia.
