Quest DiagnosticsWhat this laboratory test evaluates
DetailsdRVVT Screen with Reflex to dRVVT Confirm and dRVVT 1:1 Mix – The dilute Russell Viper Venom time integrated test is a sensitive method for the detection of Lupus Anticoagulants (LA). LA are autoantibodies that target protein-phospholipid complexes and are found in a variety of clinical conditions. In some patients, a confirmed positive result is associated with an increased thrombotic risk, and is often found in women who have recurrent fetal loss. As Lupus anticoagulants reflect a heterogenous group of antibodies, international consensus guidelines on testing require at least two screening assays be used for a complete evaluation. Refer to Lupus Anticoagulant Comprehensive Evaluation which includes the DRVVT plus a second pathway of testing, the PTT-LA with reflex to Hexagonal Phase Confirm and Thrombin Time.
Note: Target specific anticoagulant therapy (anti-XA, anti-thrombin) may cause false positive results.
What type of sample is required for this test?1 mL frozen platelet-poor plasma collected in a 3.2% sodium citrate (light blue-top) tube

How Sunridge uses laboratory information
Sunridge considers the medical question, symptoms, history, medications, prior results, and whether the finding could change care before recommending testing. A laboratory result is not interpreted in isolation and does not establish a diagnosis by itself.
Before requesting this test
Availability, collection requirements, eligibility, and processing estimates can change. Sunridge reviews each request and, when appropriate, creates the order through Fullscript. Follow the current instructions supplied with the approved order.
