I had an MCV reading of 100, blood-test done via GP.  I need a medical through the DVLA soon - in order to renew my Driving vehicle licence as I was disqualified for a drink-driving offence.  Although I have not drank any alcohol at all for nearly 9 weeks now I still consider the MCV of 100 as high?  How do I help lower it? Gina.
Hi, dairy have gone through your question. I can understand your concern.  Most common cause of high MCV is it b12 deficiency.  Other causes are folic acid deficiency, alcoholism, liver disease etc. You may have it b12 deficiency.  You should go for estimation of it b12 level.  Then take treatment with it b12 injection accordingly.  You will get benefits.  Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
