MCV (Mean Corpuscular Volume) is a measurement of the average size of red blood cells: mean = average size; corpuscular = red blood cell; volume (fluid) fL

MCH (Mean Corpuscular Hemoglobin) measures the average amount of hemoglobin in each red blood cell. Low MCH = pale red blood cells, often seen in iron-deficiency anemia.
Doctors often look at MCV and MCH together to determine the type and cause of anemia.
MCV means Mean Corpuscular Volumen. High values are sign of microcytic anemia which is a condition where the red blood cell (RBC) is not having enough vitamin B12 or folic acid in the RBC body. Low values is called, Microcytic anemia which indicates iron deficiency anemia. Mean corpuscular hemoglobin (MCH) goes hand on hand with MCV. High MCH is a sign of macrocytosis and no further tests is needed.
MCH stands for mean corpuscular hemoglobin.
MCV stands for mean corpuscular volume.
These values are used to assess the amount of hemoglobin but are usually not of much use to a lay person.
The average amount of hemoglobin and the size, respectively of a patient's red blood cells.
