Processing Instructions: 1. Collect specimen and place on wet ice. Note: Thrombin-activated tubes should not be used for collection.2. Centrifuge immediately or within 4 hours of collection if the specimen is kept at Refrigerated temperature.3. Being careful to ensure that no buffy coat is transferred, aliquot plasma into a plastic vial and freeze.Preferred Volume: 0.5 mL plasmaMinimum Volume: 0.3 mL plasmaTransport Temperature: FrozenStability: Ambient: UnacceptableRefrigerated : UnacceptableFrozen: 14 daysPerforming Lab: Mayo Clinic Laboratories
