Possible diagnoses please!! (liver disease?)?

My Father (54) has been ill for about 2 and a half weeks, here are the symptoms; rapid wight loss, blood in urine (smokey brown color); loss of appetite; fatigue. he has had some blood and urine tests but, they came back inconclusive. They told him that his liver enzymes were 10 times the normal limit (2000 instead of 200). He will be given an appointment with a specialist next week (they didn't say what kind of specialist), but i would just like to have a better idea of what could be wrong. I have done a bit of searching on the internet and the most likely thing i could find, is some sort of liver disease. Obviously you would need to have more details, but could anyone provide me with possible diagnoses for the above symptoms?
