Liver Biopsy

Updated: September 01, 2020

What is the test?

A liver biopsy takes a sample of your liver tissue so that it can be examined under a microscope. Liver biopsy is useful for determining the cause and best treatment of multiple different types of liver condition, including hepatitis and cancer.

How do I prepare for the test?

You will need to sign a consent form giving your doctor permission to perform this test. Tell your doctor if you have ever had an allergic reaction to lidocaine or the numbing medicine used at the dentist's office. If you are taking insulin, discuss this with your doctor before the test. If you take aspirin, nonsteroidal anti-inflammatory drugs, vitamin E or other medicines that affect blood clotting, talk with your doctor. It may be necessary to stop or adjust the dose of these medicines before your test. You will also have blood tests to find out if you are at extra risk for bleeding after the procedure.
