Why is this test important?
This panel helps in evaluating liver health by checking for liver injury and function. It distinguishes between different types of liver injuries and can be particularly useful for people taking medications that might affect the liver, those with viral hepatitis, chronic liver disease symptoms, high risk of liver disease, lifestyle factors for nonalcoholic fatty liver disease, or a family history of liver disease.

What does it measure?
  • ALT and AST levels to assess liver cell injury.
  • ALP and bilirubin levels to check for bile duct problems.
  • Albumin and total protein levels to evaluate the liver's ability to make proteins.

Who might need this test?
Providers might recommend this test for individuals showing signs of liver issues, those with a family history of liver disease, or individuals at risk due to lifestyle or medication use.

What type of sample is required for this test?
2 mL plasma collected in a lithium heparin (green-top) tube.

Understanding Your Results
Abnormal results may indicate liver issues and require further testing for a definitive diagnosis. It's important to discuss your results with your provider, who will consider them in the context of your overall health and medical history.
