Low B12 leading to pernicious anemia will cause MCV to rise as can folic acid and thryoid disease. Alcohol related blood dyscrasia can elevate MVC, as can other types of liver disease. If you hemaglobin/hematocrit is normal that pretty much rules out pernicious anemia unless very early stages. http://emedicine.medscape.com/article/203858-overview#a0104 Recommend some additional testing.
