Part Description

LP185873-9   dRVVT percent correction
Dilute Russell viper venom time (dRVVT) is a screening laboratory test for detecting 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 confirmatory dRVVT test measures dRVVT in the presence of excess phospholipid, which saturates the antibody binding sites and thereby diminishes the inhibitory effect of the LA, resulting in a normalization of the dRVVT. The dRVVT screen to confirm ratio is calculated as Screen dRVVT/Confirm dRVVT, and the dRVVT percent correction is calculated as [(Screen dRVVT - Confirm dRVVT)/Screen dRVVT]x100.
