Venous Thrombosis Hypercoagulability Panel with Reflex
Use
This panel evaluates for the most common hereditary and acquired venous thrombophilia risk factors.
Special Instructions
Whole blood sample is for the Factor V Mutation Analysis and Prothrombin (Factor II) Mutation Analysis. Platelet‑poor plasma is for remaining tests. Platelet‑poor plasma: Centrifuge light blue‑top tube 15 minutes at approximately 1500 x g within 60 minutes of collection. Using a plastic pipette, remove plasma, taking care to avoid the WBC/platelet buffy layer and place into a plastic vial. Centrifuge a second time and transfer platelet‑poor plasma into six plastic vials. Reflex testing: If the Hexagonal Phase Confirm is positive or weakly positive, a Thrombin Clotting Time will be performed at an additional charge. If the dRVVT Screen is prolonged (>45 seconds), the dRVVT Confirm is performed at an additional charge. If the dRVVT Confirm is positive, a dRVVT 1:1 Mix will be performed at an additional charge.
