Specimen Collection & Preparation

Specimen Requirements:

-OR-

3.0 mL Whole Blood in a Lavender Top Tube - EDTA
Minimum Volume:
1.5 mL Whole Blood*

* This volume does not allow for repeat testing

Collection Instructions:

Mix tube by inversion 5 times

Do not centrifuge

Specimens must not be clotted. Overfilling or underfilling may allow blood to clot. Specimens may be rejected due to improper storage or age of specimen.


Rejection Criteria:

Clotted specimens


Transport and Storage:
  • Ambient (18-24°C): 24 Hours
  • Refrigerated (2-8°C): 48 Hours

Test Comments:

Manual differential or peripheral smear review for morphology will reflex based on established criteria.

 

IPF (Immature Platelet Fraction) is a measurement of thrombopoietic activity that helps determine the cause of thrombocytopenia (platelet production vs. platelet destruction).

At PRMC, PCI, PDH, PVH, PKH, PBRY:

If PLT is <50,000, it will automatically reflex the PLT-F to run with the IPF value. IPF value will be reported.
