What does MCH stand for in red blood cells?

An MCH value refers to the average quantity of hemoglobin present in a single red blood cell. Hemoglobin is the protein in your red blood cells that transports oxygen to the tissues of your body. Your MCH value is related to two other values, mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC).

What’s the difference between low MCH and high MCH?

This means there aren’t as many red blood cells circulating in your bloodstream. If you have a low MCH value, you may experience the following symptoms: An MCH value calculated above 33.2 pg is considered high MCH. This means that there is a larger amount of hemoglobin present per red blood cell.
