Hi, my father had a liver transplant a month ago in India, His liver enzymes (AST,ALT,GGT and Ap) are rising since his discharge 2 weeks after transplant. Doctors (hepatologists) are unable to diagnose the problem. todays values are ALT 287, AST 307, GGT 511, AP 300. Total Billirubin 1.7. what do you think could be the problem??
