What laboratory findings should prompt a nurse to notify the healthcare provider for a client who had a liver transplant?

Rising aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels are significant laboratory findings following a liver transplant because they indicate potential liver injury or dysfunction. After a transplant, it is crucial to monitor liver function closely, as elevated levels of these enzymes suggest that the liver is not functioning effectively or that there is an underlying issue, such as rejection or an infection. Early identification of changes in liver enzyme levels allows for timely intervention, which is essential to prevent serious complications.

In the context of liver transplants, increased AST and ALT levels are particularly alarming because they provide direct information about hepatocellular damage. While other lab findings, such as potassium levels, bilirubin levels, and alkaline phosphatase levels, can also be important, the primary concern in the immediate postoperative period typically revolves around the liver’s ability to function properly, which is indicated by AST and ALT levels.
