MCH quantifies the amount of hemoglobin per red blood cell.
The normal range for MCH is between 27.5 and 33.2 picograms (pg).
High MCH scores are commonly a sign of macrocytic anemia. This condition occurs when the blood cells are too big, which can be a result of not having enough vitamin B12 or folic acid in the body. High MCH scores may also be the result of the following: liver diseases.
You may experience the following symptoms:
- shortness of breath.
- chest pain.
- fast heartbeat.
- fatigue or weakness.
- very pale or yellowish skin.
- headache.
A low mean corpuscular hemoglobin (MCH) means that your red blood cells contain less hemoglobin than normal. This usually also means they are smaller than normal (microcytic). People with small red blood cells (microcytosis) often do not show any symptoms unless their anemia is severe.
