Just tested for high MVC

I am an average healthy 27 yr old, I run and surf weekly and live a balanced life, I went in for a check up and blood tests came back with High MVC, the first question the doctor asked me was if I drink. I drink maybe 2x a week, for example have had 2 pints of cider this whole week and few glasses of wine last week, typical and of course have had my share of party nights back in the day, but nothing that screams alcoholic like I believe they are asking. I am going in for more tests tomorrow and wondering what further tests I should ask for and questions I should bring up to the doctor. I am American and never had proper health care til just moving to UK few months ago, so this is all new. I have always taken vitamins, eaten healthy and cleansed regularly and now really concerned about this. Any advice would help. Thank you
