mean corpuscular hemoglobin (MCH)

The mean corpuscular hemoglobin (MCH) is the amount of hemoglobin in a single erythrocyte. It is expressed in picograms (pg). Normal human values range from 27 to 31 pg/cell. MCH can be calculated as [Hb]/RBC (i.e. the ratio of hemoglobin concentration to red blood cell count).

See also complete blood count (CBC).
