Plasma

1. Evacuated collection tubes must be filled to completion to ensure a proper blood to anticoagulant ratio.
2. Mix the sample at least 6 times to ensure adequate mixing of the anticoagulant with the blood.
3. Centrifuge and carefully remove the plasma using a plastic transfer pipette, being careful not to disturb the cells.
4. Transfer the plasma into a plastic transfer tube with screw cap, freeze immediately and maintain frozen until tested.
5. To avoid delays in turn around time when requesting multiple tests on frozen samples, submit separate samples for each test requested.
   

Frozen - 11 days
