Mean Corpuscular Hemoglobin (MCH)

Mean Corpuscular Hemoglobin (MCH) is a measurement of the average amount of hemoglobin contained in an individual red blood cell (RBC) in a sample of blood. It is expressed in picograms (pg) and provides important information about the overall health of red blood cells.

In a complete blood count (CBC) test, the MCH level is calculated as part of the analysis of red blood cell indices, which includes Mean Corpuscular Volume (MCV), MCH, and Mean Corpuscular Hemoglobin Concentration (MCHC). The MCH is calculated by dividing the total amount of hemoglobin in red blood cells by the number of red blood cells.

Abnormal MCH levels can indicate various conditions, such as anemia or macrocytosis. A healthcare provider can interpret the results of a CBC and make recommendations for treatment or lifestyle changes as needed. The normal range for MCH levels may vary depending on the laboratory that performs the test. It is important to keep in mind that the results of a CBC can be influenced by factors such as age, gender, and overall health.
