🩸 Reticulocyte Production Index (RPI)

Assess bone marrow response to anemia in the context of uremia/ESA therapy.

Enter the percentage from lab report (e.g., 2.3 for 2.3%)
Current patient hematocrit
Formula: RPI = (Retic % × (Patient Hct / 45)) / Maturation Factor
Maturation Factor: Based on Hct: < 25% = 2.0 | 25-30% = 1.8 | 30-35% = 1.5 | > 35% = 1.0
Interpretation: RPI > 3 = Good marrow response | RPI 2-3 = Borderline | RPI < 2 = Inadequate/Hypoproliferative
