5'Nucleotidase
Also known as: 5NUCL
Use
The 5'Nucleotidase test is primarily used to evaluate liver function and to help differentiate whether an enzyme elevation is due to a hepatocellular pattern or a cholestatic pattern. It can be particularly useful in determining the cause of liver dysfunction when other test results are ambiguous.
Special Instructions
