I have had a high MCV for at least 7 years.   it has ranged from 100.1 to the latest test that showed 104.2.  It seems to be getting higher over the years.  I have seen a hemotologist several times and they can find nothing wrong.  All  other blood counts are normal.   Should I be concerned?
Hi, dairy have gone through your question. I can understand your concern. There are many causes of high MCV. Most common is It. B12 or folic acid deficiency. You should check that levels. Other cause is alcohol. Avoid alcohol if you are taken that. Many persons have high MCV without any abnormality. If you're all blood count is normal then no need to worry. It can be seen as normal variation also. Just be relaxed. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor.
