LABCORP LAB: LT BLUE TOP-CITRATE: (Frozen) Min Vol: 1

Preferred specimen: Light Blue Top Tube

Specimen: Plasma, frozen Volume: 1 mL Minimum Volume: 1 mL Specimen Container: Light Blue Top Tube Specimen 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 unless the sample is collected using a winged (butterfly) collection system. With a winged blood collection set a discard tube should be drawn first to account for the dead space of the tubing and prevent under-filling of the evacuated tube.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 alternative 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. Please print and use the Volume Guide for Coagulation Testing to ensure proper draw volume. Transport Temperature: Frozen Turn-around-time (From date of pickup of specimen by Labcorp): 1-3 days Cause for Rejection: Gross hemolysis; clotted specimens; specimens that have thawed in transit; improperly labeled specimen.
