The Full form of MCV is Mean Corpuscular Hemoglobin. MCH levels refer to the average amount of hemoglobin found in the red blood cells in the human body. Hemoglobin is a protein in the blood that allows red blood cells to transport oxygen to the cells and tissues in the body. MCH value is related to two other values, mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC). Together, MCV, MCH, and MCHC are sometimes referred to as RBC indices. MCH level is determined with a CBC (complete blood count) panel. The doctor will order a CBC panel to screen for a large range of conditions, including infection and anemia. The CBC tests white and red blood cells, as well as platelets. Mean Corpuscular Hemoglobin is calculated using the red blood cell analysis. MCH is calculated by dividing the amount of hemoglobin in a given volume of blood by the number of red blood cells present. The normal range for MCH is between 27.5 and 33.2 picograms (pg). An MCH value below 27.5 pg is considered as low MCH. This means that there’s a low amount of hemoglobin present per red blood cell. Similarly, an MCH value calculated above 33.2 pg is considered high MCH. This means that there is a larger amount of hemoglobin present per red blood cell.
