Specimen Collection & Preparation

Specimen Requirements

3.0 mL Whole Blood in a Lavender Top Tube - EDTA

Alternate Specimen

0.3 mL but no more than 0.5 mL Whole Blood in a Lavendar Microtainer

TransportAndStorage

24 hours Ambient
48 hours Refrigerated

Specimens may be rejected due to blood changes or deterioration resulting from improper storage or age of specimen

Collection Instructions

Mix tube by inversion 5 times

Specimens must not be clotted. Overfilling or underfilling may allow blood to clot.

Test Comments:

If indicated, a Manual Differential will be performed and resulted in place of the Auto Differential. 

IPF Result Comment: IPF is measurement of thromopoietic activity that helps determine the cause of thrombocytopenia (platelet production vs. plt destruction)


PRMC/PVH/PCI: If PLT <50,000, IPF% (Imm PH Fract) will be reflexed.
