I am a 40 yr old female, I recently had my yearly blood work done, and the results on it was all in range except my Ast level was a 9, and my alt level was a 4, which on my labs are below (out of range), I tried looking on the internet, but all I read are meanings for high level (out of range) results, My doctor says as long as the others are in range, there is no concern for those levels, I was a heavy drinker in my 20's I now drink about 6-7 beers on Fridays and Saturday, could these results be alcohol related.
