A liver biopsy is a procedure used by Dr. Jones to remove a small piece of the liver so it can be examined with a microscope for signs of damage or disease. The three main types of liver biopsy are percutaneous, transvenous, and laparoscopic.

A liver biopsy is performed when a liver problem is difficult to diagnose with blood tests or imaging techniques, such as ultrasound and x-ray. More often, a liver biopsy is performed to estimate the degree of liver damage—a process called staging—that helps guide treatment.
