Mean corpuscular hemoglobin

The mean corpuscular hemoglobin (MCH), or "mean cell hemoglobin" (MCH), is the average mass of hemoglobin per red blood cell in a sample of blood. It is reported as part of a standard complete blood count. MCH value is diminished in hypochromic anemias.[1]

It is calculated by dividing the total mass of hemoglobin by the number of red blood cells in a volume of blood.

MCH=(Hgb*10)/RBC [2]

A normal value in humans is 27 to 31 picograms/cell.[1] Conversion to SI-units: 1 pg of hemoglobin = 0.06207 femtomol.[3] Normal value converted to SI-units: 1.68 - 1.92 fmol/cell.
