Clinical Use:

To assist in the determination of a cause of bleeding in a patient with normal aPTT and PT.

Specimen Type:

Plasma (3.2% citrated), frozen

Requested Volume: 

6 mL frozen citrated plasma (2 mL into each of three tubes)

Minimum Volume: 

Minimum: 3 mL frozen citrated plasma (1 mL into each of three tubes)

Container Type: 

Blue-top (sodium citrate) tube

Patient Preparation: 

Do not draw from an arm with a heparin lock or heparinized catheter.

Collection:

Citrated plasma samples should be collected by double centrifugation. Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate.1 Evacuated collection tubes must be filled to completion to ensure a proper blood to anticoagulant ratio.2,3 The sample should be mixed immediately by gentle inversion at least six times to ensure adequate mixing of the anticoagulant with the blood. A discard tube is not required prior to collection of coagulation samples, except when using a winged blood collection device (ie, “butterfly”), in which case a discard tube should be used.4,5 When noncitrate tubes are collected for other tests, collect sterile and nonadditive (red-top) tubes prior to citrate (blue-top) tubes. Any tube containing an alternate anticoagulant should be collected after the blue-top tubes. Gel-barrier tubes and serum tubes with clot initiators should also be collected after the citrate tubes. Centrifuge for 10 minutes and (using a plastic transfer pipette) carefully remove two-thirds of the plasma without disturbing the cells. Deliver to a plastic transfer tube, cap, and recentrifuge for 10 minutes. Use a second plastic pipette to remove the plasma, staying clear of the platelets at the bottom of the tube. Transfer the plasma into a LabCorp PP transpak frozen purple tube with screw cap (LabCorp No. 49482). The specimen should be frozen immediately and maintained frozen until tested.

Storage Instructions:

Freeze plasma, refrigerate serum, and maintain whole blood and buccal swab kit at room temperature or refrigerate.
