Collection Instructions:

Draw to the proper fill level (do not overfill or underfill) because the correct ratio of blood to citrate is critical (9:1). Mix by gentle inversion 3 – 4 times.

Centrifuge for 15 min at 1500 x g within 60 minutes of collection. Remove plasma using a plastic pipette being careful not to disturb the buffy coat. Repeat centrifugation at 1500 x g for 15 minutes to assure complete platelet removal.

Dispense the plasma into labeled, screw-top plastic tube(s) using a plastic transfer pipette. Freeze immediately.

Stable for 6 months at -20 C. Specimen must remain frozen at all times. Avoid hemolysis.
Do not submit a hemolyzed specimen, or a one having microclots present.
