Mean corpuscular hemoglobin

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. 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.
