<qa>  What is the maximum limit of normal serum bilirubin?Serum total bilirubin less than 2.5 mgdl, and serum ALT and AST values less than or equal to 2.5 times the upper limit of normal. Values above these levels may be accepted, at the discretion of the PI or study chairman, if such elevations are thought to be due to liver involvement by malignancy. If these values do not normalize during induction chemotherapy, such patients will not be eligible for the transplant phase of the protocol, and will thus be taken off study.
