|Specimen: || Collect: Protease Inhibitor Tube. This is the only acceptable collection tube.|
Specimen Preparation: A winged collection set (Butterfly) must be used to fill the Protease Inhibitor Tube. If this is the only tube collected, a waste tube should be collected first and discarded.
NOT RECOMMENDED: Filling collection tubes directly through a needle/tube-holder assembly increases the risk of chemical reflux back into the vein of the patient.
WARNING: Collection tubes are NOT STERILE.
Mix Collection tube thoroughly. Separate the plasma from cells within 1 hour of collection by centrifugation in a refrigerated centrifuge. Transfer 1 mL plasma to an ARUP Standard Transport Tube and freeze. (Min: 0.5 mL) Do not submit the collection tube for testing.
Storage/Transport Temperature: Frozen. Separate specimens must be submitted when multiple tests are ordered.
Unacceptable Conditions: Grossly hemolyzed specimens.
