6. Given the following data, compute for the patient’s ARC, CRC and RPI. Show your solutions.
RBC count = 4.0 x 1012 /L
Hct = 25%
Reticulocyte (%) = 3%
7. Given the following values, calculate the Reticulocyte count (%) of the patient. Show your
solution.
Reticulocytes (%): 50 % Hematocrit: 45% RBC: 5.0 x 10 12/L
8. If a male patient has a reticulocyte count of 10.0 %, RBC of 3.30 x 10 12/L and a packed cell
volume of 30%, what is his Reticulocyte Production Index (RPI)? Show your solution.
9. If a female patient has a reticulocyte count of 7.0 %, RBC of 3.90 x 10 12/L and a hematocrit of
35 %, what is her Corrected Reticulocyte Count (CRC)? Show your solution.
10. What are the possible sources of error in reticulocyte count?
