Mean corpuscular hemoglobin (MCH) is a calculation of the average amount of hemoglobin inside a single red blood cell. Mean corpuscular hemoglobin concentration (MCHC) is a calculation of the average concentration of hemoglobin inside a single red blood cell. Red cell distribution width (RDW) is a calculation of the variation in the size of RBCs.
MCH blood test. An MCH blood test checks your Mean Corpuscular Hemoglobin. MCH is part of a CBC or complete blood count. The test is designed to measure the average amount of hemoglobin carrying oxygen inside red blood cells. Some cells will have an MCH that is higher, whereas red cells that are microcytic will have lower values.
