Mean Corpuscular Hemoglobin (MCH)

The MCH is a measure of the amount (weight) of hemoglobin in a red blood cell.

This measurement is clinically significant in the presence of anemia as it allows for categorizing the type of anemia.

  • Elevated MCH is associated with macrocytic anemia
  • Diminished MCH is associated with microcytic anemia
  • Hyperlipidemia may give a false elevation of the MCH
  • MCH is most useful in severely anemic patients. Among those with lesser degrees of anemia, it is less useful because the measurement has a potential for a relatively wide range of error.

Normal Values*

MCH 26-34 pg/cell

*These are general values taken from a variety of sources. The actual normal values may vary from lab to lab and from one type of testing protocol to another.
