Blood Test Results

I previously posted that my ALT & AST were very high 388 & 256 on  12/01/11. I had another blood test done yesterday and the Alt & AST have decreased to 237 & 172 which is better but not anywhere near the 06/02/11 bloodwork of Alt 64 & AST 56. Another test GGT was done and is very high at 200 which the norm is 0-40. Drugs like alcohol and phenobarbitals or anticonvulsant drugs for epilepsy increase the GGT. I am stumped! I have not had a drink in years and I do not take Phenobarbitals. Also my sodium is low 130 but acceptable. BUN is high at 27, norm 8-25 and RBC low at 27, norm  & 4.06. Direct Biliburin high at 0.4 norm 0.0-0.2. There are other highs and lows but are not as significant. I will talk to my hepatologist today. All I have is my word about the GGT test. I am dumbfounded. Hope he has a theory of why my LFT'S are so high all of a sudden! If anyone has had any experience with this problem , please post! I would like to hear what you have to say. Thanks BostonMike.

Mike is there anything that you are eating or taking that could make that ggt level look.high ..like a false positive ...I would research that to see if there are other cause it can show up high ???
