There are many tests to measure fibrosis and cirrhosis. The most common test is the percutaneous liver biopsy. This outpatient procedure involves inserting a biopsy needle through the ribcage into the liver. It is usually preceded by an ultrasound to look for any nodules and to locate a section of the liver to remove a portion of liver tissue. The liver tissue sample is removed and examined by a pathologist who will issue a report on the health of the liver.
