Calculation of RBC constants
The red blood cell constants (mean cell volume, mean cell
hemoglobin, and mean cell hemoglobin concentration) are
calculated from the RBC, HGB, and HCT.
Mean cell volume (MCV)
The MCV is calculated from the RBC and HCT, using the
following equation:
Mean cell hemoglobin (MCH)
The MCH is calculated from the RBC and HGB, using the
following equation:
Mean cell hemoglobin concentration (MCHC)
The MCHC is calculated from the HCT and HGB, using the
following equation:
HCT (%)
MCV (fL) = ✕ 10
RBC (✕ 10

HGB (g/dL)
MCH (pg) = ✕ 10
