RPI (Reticulocyte Production Index)
(Last Updated - 7/20/2007)
-the form below uses the equation:
RPI = [Retics (%) * Hct (%)] / [45 (%) * RMT]
Where RMT = Reticulocyte Maturation Time
RMT = [(-0.05) × Patient's HCT (%)] + 3.25
RPI Ranges:
> 2 --> Suggests an effective erythropoiesis response
< 2 --> Suggests an ineffective response
