What does MCV of 101.3 and MCH of 33.2 indicate
MCV indicates RBC size, and MCH indicates haemoglobin per RBC
Welcome to Ask a Doctor service.
MCV - Mean corpuscular volume, refers to the volume of RBC, it is usually below 100 femto liters, anything above 100 indicates slightly larger red blood cells and this is usually a result of vitamin-B12 or folic acid deficiency.
MCH - Mean corpuscular haemoglobin, is a measure of the amount of haemoglobin in individual red blood cell. Your value is very marginally raised indicating a slower rate of maturation of RBC due to low vitamin-B12 deficiency.
I hope this clarifies your doubt.
