Part Description
LP185870-5 dRVVT with 1:1 Pooled Normal Plasma
Dilute Russell viper venom time (dRVVT) is one of the tests used to detect the presence of lupus anticoagulants (LA), which are autoantibodies associated with excess clot formation, excess bleeding, and repeated miscarriages. The coagulant in the venom directly activates factor X, which turns prothrombin into thrombin in the presence of factor V and phospholipid. If phospholipid antibodies are present, this reaction will be inhibited, which will prolong the screening dRVVT and suggests the presence of LA. A positive screening dRVVT result may be followed by a dRVVT mixing study using pooled normal plasma (PNP) from healthy donors as a source of coagulation factors. If the dRVVT normalizes in the mixing study, a clotting factor deficiency is presumed to be the cause of the clotting abnormality. PMID: 19624461
