Mean corpuscular hemoglobinFrom Wikipedia, the free encyclopedia

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]

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

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 = 0.062

femtomol.[3]Normal value converted to SI-units: 1.68 - 1.92 fmol/cell.
