How to lower MCV in blood?
Patient: 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. Doctor: Hi, dearI have gone through your question. I can understand your concern.  Most common cause of high MCV is vit b12 deficiency.  Other causes are folic acid deficiency, alcoholism, liver disease etc. You may have vit b12 deficiency.  You should go for estimation of vit b12 level.  Then take treatment with vit b12 injection accordingly.  You will get benefits.
