6802: CATECHOLAMINES, PLASMA
- CATECHOLAMINES, FRACTIONATED, PLASMA, EPINEPHRINE, PLASMA, DOPAMINE, PLASMA
- Transfer Tube- Frozen- Plasma
Turn Around Time
- 3 mL FROZEN EDTA or Heparin PLASMA
- 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). To avoid delays in turnaround time when requesting multiple tests on frozen samples, PLEASE SUBMIT SEPARATE FROZEN SPECIMENS FOR EACH TEST REQUESTED.
