Liver Biopsy

In a liver biopsy a sample of liver tissue is taken and analyzed to help doctors diagnose a variety of disorders and diseases in the liver. Most commonly, it is done to identify the cause of:

  • Persistent abnormal liver blood tests (liver enzymes)
  • Unexplained yellowing of the skin (jaundice)
  • A liver abnormality found on ultrasound, CT scan, or nuclear scan
  • Unexplained enlargement of the liver


  • You MUST arrange for a responsible adult (over 18) who can drive or otherwise accompany you to and from the endoscopy unit. Your procedure cannot begin until a responsible adult driver is in the unit. This person should remain in the unit during your entire visit so that they are available as soon as you are ready to be discharged. You will not be discharged unless this person is in the unit.
  • Inform your doctor of all medications you are taking.
