I think there are a few other markers that need to be elevated for them to tie it to alcohol, and I also believe that those markers are pretty sensitive. A common cold or other type of infection can raise those. At lest that was my experience. I've ran into this in the past, and all the doctors say that one or two of these markers slightly elevated do not mean that there is something major happening. I want mine all within range, but my doctor says thats just were my body is at. I do take milk thistle time to time just for my own gratification.
