Check Liver and Bile Duct Health - 5'-Nucleotidase Test

The 5'-nucleotidase (5'-NT) test measures the level of an enzyme primarily associated with the membranes of liver cells and bile ducts. Elevated levels are a qualitative indicator of biliary cholestasis (heart attack), helping to differentiate it from other causes of elevated liver enzymes, such as alkaline phosphatase (ALP).
