Plasma
Preferred Container
Light Blue Top Tube (Sodium Citrate) – Tube must be full at time of collection.
Specimen Collection and Handling
Collect specimen as follows:
1. Draw blood in light blue-top (3.2% sodium citrate) tube(s). Tube(s) must be full upon collection.
2. Separate plasma from cells as soon as possible within 4 hours of collection in a centrifuge at 2,500 rpm for 15 minutes or 3,000 rpm for 10 minutes.
3. Using a plastic transfer pipette (do not use a glass pipette) decant the plasma to a screw-capped, plastic (polypropylene) vial. Glass vials will not be accepted.
4. Spin the plasma again at 2,500 rpm for 15 minutes or 3,000 rpm for 10 minutes. Note: Double spinning the specimen ensures platelet poor plasma (<10,000 uL)
5. Divide the plasma into as many 0.5-1.0 mL aliquots as possible and cap the vial(s) tightly.
6. Place tubes upright and flash freeze specimen(s) immediately at ≤ – 20° C or below.
7. Send specimen(s) FROZEN on dry ice.
