What are total bilirubin, direct bilirubin, ALT, AST right before liver transplant?

My niece is 17 months old and she was born with a rare liver disease.  She currently has a PEBD and now is being evaluated for liver transplant.  What are total bilirubin, direct bilirubin, ALT, AST right before liver transplant? When do the numbers get dangerous?

Thanks

don't worry about the ALT and AST.  the higher the bilirubin the worse it is.  For children, the presence of malnutrition, ascites and other complications of portal hypertension are more important than the bilirubin level alone.
