  • Title: Lupus Anticoagulant Testing: Diluted Russell Viper Venom Time (dRVVT).
    Author: Pengo V, Bison E, Banzato A, Zoppellaro G, Jose SP, Denas G.

    Abstract:
    Diluted Russell Viper Venom Time (dRVVT) has become the most popular test to detect Lupus Anticoagulant (LA). dRVVT is more sensitive than other global tests employed to detect LA and is not affected by inhibitors of factor VIII or IX. The test is most successfully implemented if you observe three steps in its execution: screening, mixing, and confirmatory studies. Interference due to the presence of heparin in tested plasma must be excluded by means of thrombin time (TT). The prior use of Vitamin K Antagonists (VKAs) or Non-vitamin K Oral Anticoagulants (NOACs) must also be evaluated by means of International Normalized Ratio, or specific tests, respectively.
