RBC size: Mcv stands for mean cell volume and measures the size of a red cell. Small size can be due to iron deficiency or various inhereted kinds of anemias most commonly. Large red cells are seen with B12 deficiency, Folic Acid deficiency, alcohol abuse, liver disease, some drugs, hypothyroidism, and many kinds of bone marrow problems. Mcv is used to help find the cause of anemia.
