Immune System

A healthy result should fall into the range 29 - 42 seconds.

Dilute Russell's viper venom time (dRVVT) is a laboratory test often used for detection of lupus anticoagulant (LA). Russell's viper venom [RVV] isolated from the snake Daboia russelii contains a potent activator of factor X which in the presence of phospholipid, prothrombin and calcium ions clots fibrinogen to fibrin. In individuals with a lupus anticoagulant the antibody binds to the phospholipid inhibiting the action of the RVV and prolonging the clotting time.
