Other Acceptable Specimens
LABCORP LAB: LT BLUE TOP-CITRATE: (Frozen) Min Vol: N/A
Transport Temperature
Specimen: Plasma, frozen
Volume: 1 mL
Minimum Volume: 0.3 mL (Note: This volume does not allow for repeat testing.)
Container: Blue-top (sodium citrate) tube
Collection: 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.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. Serum gel-barrier tubes and serum tubes with clot initiators should also be collected after the citrate tubes. Centrifuge for 10 minutes and (using a transfer pipette) carefully remove two-thirds of the plasma without disturbing the cells. Deliver to a plastic transport 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. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
Storage Requirements:
Container Storage
Plasma from Light Blue Top Tube Frozen
Storage Instructions: Freeze
Cause for Rejection:
Severe hemolysis; improper labeling; clotted specimen; specimen diluted with I.V. fluids; samples thawed in transit; improper sample type; sample out of stability
