question: On a life insurance exam, I had AST of 53, ALT of 82 and GGT of 154.  I do drink alcohol, but had a ultrasound in 2008 because of high enzymes.  Everything was normal.  I have been taking Milk Thistle for the past few months in order to get levels down.   I have not re-tested.   I also take 20 mgs of Lexapro a day.  Please give me your opinion of these numbers.  Should I be alarmed?   After the 2008 scare, it really makes me nervous to be tested.  Probably wouldnt have if not for the life insurance exam.  They did approve me on a standard rating. Thanks so much
