The RBC (red blood cell) count, MCH (mean corpuscular volume) and MCHC (mean corpuscular hemoglobin concentration) are some of the results reported out on your CBC (complete blood count). The RBC is your red blood cell count, which usually ranges from 3.6 to 6.1 million red blood cells per cubic millimeter of blood. MCH and MCHC are called red blood cell indices. They measure the average amount of hemoglobin contained within your red blood cells. Don't worry about minor abnormalities in these indices.
