Mean corpuscular hemoglobin

Overview
The mean corpuscular hemoglobin, or "mean cell hemoglobin" (MCH), is a measure of the mass of hemoglobin contained by a red blood cell. It is reported as part of a standard complete blood count.

Differential diagnosis of MCH
It is diminished in microcytic anemias, and increased in macrocytic anemias. It is calculated by dividing the total mass of hemoglobin by the RBC count.

MCH=Hgb/RBC

A normal value in humans is 26.3 to 33.8 picograms/cell.
