Hi i'm a 37 yr old male and I did 2 blood test recently to start a new job and my liver function tests are a little out of range. I feel fine. I take an ocassional drink. I'm 6'2" and weigh 215 lbs.

July 14, 2010 Bloodwork: ALP: 90, AST: 40, ALT: 60, GGTP: 66, LDH: 194
Aug 10, 2010 Bloodwork: ALP: 79, AST: 41, ALT: 54, GGTP: 66, LDH: 290.

I'm very concerned as they said I should go back to my Dr and let him explain the readings but all he says is for me to go and do a CT- Scan of the liver. I feel like the Dr. is not giving me the full info. Help me, base on my findings I know the ALP & ALT are in range and the others are out, also what does the LDH means. What would cause the GGTP & AST to be elevated like that.
