Brief Answer: Not affected by drinking. Detailed Answer: Hello, Thanks for trusting us with your health concern. WBC counts and mCV are not altered by drinking a night before the tests. These reflect the long term changes in your blood picture and deficiencies. The increase in mCV can be caused by chronic alcohol intake due to folate and Vitamin B 12 deficiency. You need to find out the cause after an examination from your physician and get yourself a proper treatment. Please feel free to discuss further. I will be glad to answer the follow up queries that you have. Wishing you good health. Regards. Dr. Rakhi Tayal. For future query, you can directly approach me through my profile URL
