Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled. Blood appears red because of the large number of red blood cells, which get their color from the hemoglobin.
A lab test called the complete blood count, or CBC, measures the amount of hemoglobin in each red blood cell -- the MCH. The MCHC measures the amount of hemoglobin in each red blood cell in relation to the size of the cell. If your hemoglobin is low, your body cells do not receive adequate oxygen. complete blood count includes an MCH and MCHC. Photo Credit Keith Brofsky/Photodisc/Getty Images. Nutritional deficiencies can cause anemia; if you are anemic, your lab tests show a low MCH, or mean corpuscular hemoglobin, and low MCHC, or mean corpuscular hemoglobin concentration.
