4.3 Calculation of RBC Constant
RBC constant (mean RBC volume, mean RBC hemoglobin, mean RBC hemoglobin
concentration) is calculated from RBC, HGB, and HCT.
1. Mean RBC Volume (MCV)
Calculation is made from RBC and HCT by the formula below:
MCV (fL) =
HCT (%)
RBC (×10
6
/µL)
×10
2. Mean RBC Hemoglobin (MCH)
Calculation is made from RBC and HGB by the formula below:
MCH (pg) =
HGB (g/dL)
RBC (×10
6
/µL)
×10
3. Mean RBC Hemoglobin Concentration (MCHC)
Calculation is made from HCT and HGB by the formula below:
MCHC (g/dL) =
HGB (g/dL)
HCT (%)
×100
