Mean Corpuscular Hemoglobin (MCH)
Purpose hgb blood test - Mean corpuscular hemoglobin (MCH) is a calculation of the average amount of oxygen-carrying hemoglobin inside a red blood cell. Macrocytic RBCs are large so tend to have a higher MCH, while microcytic red cells would have a lower value.
Mean corpuscular volume (MCV) is a measurement of the average size of your RBCs. The MCV is elevated when your RBCs are larger than normal (macrocytic), for example in anemia caused by vitamin B12 deficiency. When the MCV is decreased, your RBCs are smaller than normal (microcytic) as is seen in iron deficiency anemia or thalassemias.
MCV is Mean Corpuscular Volume and it measures the size of your red blood cells. MCH is Mean Corpuscular Hemoglobin and it measures the amount of hemoglobin in a single red blood cell. Taken together, the numbers will tell your doctor what your levels of folic acid and/or B12, iron, copper and B6 are.
