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.

Critical Ranges:

Pediatric (< = 15 days old) Low Critical Limits
WBC: < = 2.0 th/ul
Hgb: < = 10.0 g/dl
Platelet: < = 30.0 th/ul
Pediatric (< = 15 days old) High Critical Limits
WBC: > = 39.0 th/ul
Hgb: > = 24.0 g/dl
Hct: > = 70.0%

Platelet: > = 850 th/ul

 
Low Critical Limits 
Abs Neut: <=0.50 th/ul
WBC: < = 1.5 th/ul
Hgb: < = 6.0 g/dl
Platelet: < = 30 th/ul
High Critical Limits 
WBC: > = 40.0 th/ul
Hgb: > = 19.0 g/dl
Platelet: > = 850 th/ul

Differential Critical Limit: Blasts, bacteria, fungi, malarial parasites


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.
