My husband's employer pays to have a health screening annually. Everything re: my bloodwork was normal except for my MCV, which was high (is was 100.....normal, I guess, is from 80-98). I followed up w/ my primary care physician who did further testing (Vitamin B and a couple other checks), but all came back normal. Liver, thyroid, kidney all fine. The only thing my doctor said is that I possibly consume too much alcohol. I do enjoy my glass of wine nightly and hate the thought of giving it up. So, my question is what is the long-term effect of having a high MCV count? Could this lead to a chronic problem?
