I don't understand any of this ??

I  had a blood test done and  my GGTP level was 185,(norm.range:8-78)  AST was 59 (norm.range:14-50) and ALT was 85 (norm range:21-72 ) what is the one  that means my liver enzymes are high ????? .I have no understanding of any of this.. I'm married (18 years never cheated) I have no pain,eat well,and sleep well.I also workout (could use to knock off 10 lbs) I am in good  health,but when i was in my 20's &30's I drank Heavy.(never did drugs) How can I get the the levels lower?. I was in Iraq (two tours) and took alot of malaria pills and have had lots of different shots and was told that I would have false positives on blood tests for up to 5 years afterwards because of the pills and shots,could this have cause it ??. How can I get the the levels lower?.The doctor didn't say anything about having any Hepatitis tests done...I'm way confused about all of this.. Should I Worry about it? ?
