Updated June 20, 2016. A red blood cell (RBC) count is a type of blood test that can provide information about how many red blood cells are in a person's blood. Knowing why your doctor ordered an RBC count and what the results of your RBC count mean is important in understanding how it relates to your health. The RBC count test might sometimes be done as one piece of a more comprehensive blood test, which is called a complete blood cell (CBC) count.
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.
