Definition. A liver biopsy is a medical procedure performed to obtain a small piece of liver tissue for diagnostic testing. Liver biopsies are sometimes called percutaneous liver biopsies, because the tissue sample is obtained by going through the patient's skin.
A liver biopsy is an accurate way to learn the condition of your liver. A liver biopsy helps: 1  diagnose liver disease and the stage it is in; 2  detect cancer and infections; and. 3  provide reasons for liver swelling or abnormal levels of liver enzymes.
