Specimen Collection & Preparation

Specimen Requirements:

Test Comments:

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.
