What is the mean cell hemoglobin (MCH)?

By William Aird

Represents mean weight of hemoglobin (Hb) per red blood cell (RBC); calculated by dividing hemoglobin (Hb) by the RBC count (RBC).

MCH = Hb/RBC

Imagine drilling a hole in a single red blood cell and weighing the hemoglobin inside. Carry out this procedure on millions of cells, and calculate the average weight. That value is the mean cell hemoglobin!
