Mean corpuscular hemoglobin (MCH) is a measurement of the average amount of hemoglobin in each red blood cell. Hemoglobin is a protein in red blood cells that carries oxygen from your lungs to organs and tissues of your body.

An MCH test is one part of a panel of tests called the red blood cell (RBC) indices, which evaluate different characteristics and functions of red blood cells. MCH is a useful measurement for understanding how effectively oxygen is being distributed throughout the body. Changes in MCH or other RBC indices may be a sign of a blood disorder called anemia.
