What causes a high MCV in blood test?
Patient: I had a blood test done and my MCV was 104 one Dr. told me to cut back on alcohol, I had the same test run by another Dr and they asked me how much red meat I ate in my diet, when I told them very little they said that's why I had a high MCV test. A little confusing. Doctor: Mean corpuscular volume or MCV is the average amount of space occupied by each red blood cell. Red blood cells help carry oxygen in the blood.A normal MCV is usually considered to be from 80-100.High MCV can be due to macrocytic anemia ,due to some drugs, liver disease, hypothyroidism, folic acid deficiency, liver problems and thyroid problems.RegardsDr DE
