2.7 mL blood in light blue-top (3.2% sodium citrate) PLASTIC tube
Specimen Required
1.0 mL citrate plasma, 2 vials of 0.5 mL each
Specimen Min Vol
0.5 mL citrate plasma FROZEN
Specimen Preparation
Immediately centrifuge at 3,500 rpm for 10 minutes to completely remove platelets if sending plasma
Storage/Transport Temperature
Refer to Specimen stability criteria as shown below
Ambient
4 hours citrate whole blood
Refrigerated
Unacceptable
Frozen
2 weeks
Unacceptable Conditions
SPECIMENS COLLECTED IN GLASS TUBES, specimens that exceed stated stability, unlabeled/mislabeled/mismatched specimens, specimens submitted in leaking containers, clotted, hemolyzed or under-filled tubes
Special Instructions
A clean venipuncture is essential to avoid specimen activation. The correct ratio of blood to anticoagulant (9:1) is critical. If the tubes are under-filled, specimen must be recollected as results will not be accurate. DO NOT COLLECT IN GLASS TUBES.
