Special Instructions

• 2 transfer tubes with 3 mL Frozen Citrated Plasma

Additional Information

• 2 Frozen Citrated Plasma samples with 3.0 mL in each tube per; 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 tube. Gel-barrier tubes and serum tubes with clot initiators should also be collected after the citrate tubes. Centrifuge and (using a transfer pipette) carefully remove the plasma without disturbing the cells. Transfer the plasma into a 2 plastic transport tubes with screw cap and the specimens 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 specimen for each test requested. LCA
