Not to be confused with mean corpuscular hemoglobin concentration, although they are predictably correlated in healthy states.

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.

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

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

Worked example

Measure	Units	Conventional units	Conversion
Hct	40%
Hb	100 grams/liter	10 grams/deciliter	(deci- is 10−1)
RBC	5E+12 cells/liter	5E+6 cells/μL	(micro is 10−6)
MCV = Hct / RBC	8E-14 liters/cell	80 femtoliters/cell	(femto- is 10−15)
MCH = Hb / RBC	2E-11 grams/cell	20 picograms/cell	(pico- is 10−12)
MCHC = MCH / MCV	250 grams/liter	25 grams/deciliter	(deci is 10−1)
