Corrected reticulocytes and production index

Show corrected reticulocyte percentage and RPI using explicit reference and maturation inputs.

Intended population: Anemia assessment with an independently chosen reference hematocrit and reticulocyte maturation factor.

Reference hematocrit and maturation correction depend on the patient and method. Both are entered explicitly; the tool does not infer them from hematocrit or sex. Corrections are approximate and do not replace the smear, absolute count or clinical assessment.

Measured reticulocytes (%)

Patient hematocrit (%)

Selected reference hematocrit (%)

Selected maturation correction factor (days relative to 1-day baseline)
