What does low MCV MCH Mchc in blood test mean?
Mean Corpuscular Volume (MCV) helps diagnose the cause of an anemia. Low values suggest iron deficiency. Mean corpuscular hemoglobin, or “mean cell hemoglobin” (MCH) is the average mass of hemoglobin per red blood cell in a sample of blood. MCH value is low in hypochromic anemias. Hypochromic anemia may be caused by vitamin B6 deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections (e.g. hookworms) or other diseases, therapeutic drugs, and lead poisoning. It may also occur from severe stomach or intestinal bleeding caused by ulcers or medications such as aspirin.It can also occur in thalassemia.
