Liver biopsy is a diagnostic procedure in which a small sample of liver tissue is collected and examined under a microscope to help diagnose liver diseases or conditions. It is often performed to determine the extent of liver damage, the presence of inflammation or infection, or the presence of abnormal cells. Liver biopsy can be done using different methods, including percutaneous biopsy, transjugular biopsy, or laparoscopic biopsy. The information obtained from a liver biopsy is important for guiding treatment decisions and monitoring the progression of liver diseases.
