dRVVT W excess phospholipid (LA confirm)
Active
Term Description
If the coagulation defect corrects with excess phospholipid, it confirms the likely presence of phospholipid antibodies and the LA syndrome. Platelets, bilayer and hexagonal phospholipids are variously used as the source of excess phospholipids and this term covers them all. The use of one term for these variations reduces mapping work for practices that import laboratory results, but laboratories that use hexagonal phospholipids and think it important to distinguish their source can use 75883-9 instead of this term.

LP65493-6 Coagulation dilute Russell viper venom induced.excess phospholipid
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. PMID: 19624461

LP21280-0 Dilute Russell viper venom time
Dilute Russell's viper venom time (dRVVT) is a laboratory test for lupus anticoagulant (LA). This in vitro diagnostic test is based on the property that the venom of the Russell's Viper is effective at inducing thrombosis. The coagulant in the venom directly activates factor X, which turns prothrombin into thrombin in the presence of factor V and phospholipid. The venom is diluted to give a clotting time of 23 to 27 seconds and the phospholipid is reduced to make the test extremely sensitive to phospholipid. The dRVVT test is more sensitive than the aPTT test for the detection of lupus anticoagulant (an autoimmune disorder), because it is not influenced by deficiencies in clotting factors VIII, IX or XI. The dRVVT is thought to be more sensitive than the activated partial thromboplastin time (aPTT) for detection of lupus anticoagulants.
