Specimen Requirements

Specimen

Serum, plasma, and whole blood

Volume

1 mL serum, 2 mL plasma (sodium citrate), and 4 mL whole blood (EDTA)

Minimum Volume

1 mL serum, 1 mL plasma (sodium citrate), and 4 mL whole blood (Note: This volume does not allow for repeat testing.)

Container

Gel-barrier tube, blue-top (sodium citrate) tube, and lavender-top (EDTA) tube

Collection Instructions

Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate. Evacuated collection tubes must be filled to completion to ensure a proper blood to anticoagulant ratio. 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. 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 tube. Gel-barrier tubes and serum tubes with clot initiators should also be collected after the citrate tubes. Centrifuge and carefully remove the plasma using a plastic transfer pipette, being careful not to disturb the cells.Transfer the plasma into a Labcorp PP transpak frozen purple tube with screw cap (Labcorp No. 49482). Freeze plasma within four hours of blood collection and maintain frozen until tested. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit seperate frozen specimens for each test requested.

Storage Instructions

Frozen: Plasma

Room Temperature: Serum and whole blood (EDTA)
