Specimen Retention

  • Draw blood in lavender-top (EDTA) tube or green-top (heparin) tube. Invert to mix with preservatives. Centrifuge and transfer the plasma to labeled plastic transport tube. Freeze immediately (within one hour after collection) at -20(degrees)C and ship frozen. The time between blood collection and the preparation of plasma is quite critical; if the time exceeds one hour, catecholamine values increase (when blood is kept at 4(degrees)C) or decrease (when left at 20(degrees)C).[1] To avoid delays in turnaround time when requesting multiple tests on frozen samples, PLEASE SUBMIT SEPARATE FROZEN SPECIMENS FOR EACH TEST REQUESTED.
