MCH: What It Means for Your Health
MCH measures the average mass of hemoglobin in each red blood cell. It correlates closely with MCV — smaller red blood cells tend to have less hemoglobin per cell. MCH is useful for distinguishing between types of anemia and is part of the standard red cell indices reported in a CBC.
Reference Range
Reference ranges may vary between laboratories, age groups, and sexes. The values shown are general adult reference ranges. Always compare your results to the specific range provided by your testing laboratory.
What Is MCH?
MCH measures the average mass of hemoglobin in each red blood cell. It correlates closely with MCV — smaller red blood cells tend to have less hemoglobin per cell. MCH is useful for distinguishing between types of anemia and is part of the standard red cell indices reported in a CBC.
Commonly included in:
What Does High MCH Mean?
Elevated MCH often accompanies macrocytic anemia from vitamin B12 or folate deficiency, liver disease, or excessive alcohol intake. Larger red blood cells naturally contain more hemoglobin per cell.
What Does Low MCH Mean?
Low MCH (hypochromia) typically indicates iron deficiency anemia or thalassemia, where red blood cells are smaller and contain less hemoglobin than normal. This results in cells that appear pale under a microscope.
