Corrected Reticulocyte Percentage/Reticulocyte Production Index (RPI)
Evaluates bone marrow response to anemia, often in sickle cell patients.
INSTRUCTIONS
This tool provides multiple calculations:
- Absolute reticulocyte count:
- The number of reticulocytes in a volume of blood.
- Use when a direct measure of red blood cell production is needed, such as in early treatment response or non-anemic conditions with altered RBC turnover.
- Corrected reticulocyte percentage/reticulocyte index (RI):
- Adjusts the reticulocyte percentage to account for the degree of anemia.
- Can be appropriate as a quick assessment of marrow response in mild to moderate anemia, where adjusting for maturation time may not be necessary.
- Reticulocyte production index (RPI):
- Adjusts the reticulocyte index to account for the longer maturation time of reticulocytes released prematurely from the bone marrow.
- Useful in moderate to severe anemia, where reticulocytes are often released early.
