---|---|---|---|
FHEXC | Hexagonal Phase Confirm | No | No |
FDVTC | DRVVT Confirm | No | No |
FDVTX | DRVVT 1:1 Mix | No | No |
FCLOT | Thrombin Clotting Time | No | No |
If the PTT-LA is prolonged (>40 seconds), then the Hexagonal Phase Confirmation (FHEXC) will be performed at an additional charge.
If the Hexagonal Phase Confirm is positive or weakly positive, a Thrombin Clotting Time (FCLOT) will be performed at an additional charge.
If the DRVVT Screen is prolonged (>45 seconds), then the DRVVT Confirmation (FDVTC) will be performed at an additional charge.
If the DRVVT Confirmation is positive, then the DRVVT 1:1 Mix (FDVTX) will be performed at an additional charge.

Plasma Na Cit
Collection Container/Tube: Light-blue top (3.2% sodium citrate)
Submission Container/Tube: Plastic vial
Specimen Volume: 3 mL platelet-poor plasma, in plastic vial
Collection Instructions: Draw blood into a 3.2% sodium citrate (light blue-top) tube. Centrifuge light blue-top tube 15 minutes at approx. 1500 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 a new plastic vial. Plasma must be free of platelets (<10,000/mcl).
Freeze immediately and ship on dry ice.
