MCH Blood Test Causes, Results and Overview

What low levels of MCH means. If a person has an MCH level that is below 26 it shows that they may have an acute iron deficiency, microcytic anemia or hemoglobinopathy. If a person has microcytic anemia, their red blood cells are smaller and contain a smaller amount of hemoglobin. Typically, when a person has microcytic anemia they are iron deficient. When a person is iron deficient, they are not getting enough iron in their blood. This causes the heart to have to work harder and can lead to a variety of symptoms.
