Specimen Collection & Preparation

Specimen Requirements:

-OR-

3.0 mL Plasma from a Green Top Tube - Na Heparin in a Plastic Vial
Minimum Volume:
0.4 mL Plasma*

* This volume does not allow for repeat testing

Collection Instructions:

Use Betadine or Zephiran as a skin preparation for blood collection.

Do not use alcohol or alcohol containing solutions as a skin preparation for drawing specimen.


Processing Instructions:

Centrifuge for 10 minutes at 1100 - 1300 g in a swing bucket unit or 15 minutes in a fixed angle. 

Separate plasma from cells within 2 hours of collection.

Transfer serum or plasma to a tightly-capped tube to minimize alcohol loss.

Send to Parkview lab iced. Due to smearing of print while on ice, please label specimen following procedure and a second label in the pocket of transport bag with requisition.


Rejection Criteria:

Frozen

Serum Separator Tube (SST)

Plasma Separator Tube (PST)
