What is the main purpose of a liver biopsy?

The primary purpose of a liver biopsy is to assess liver tissue for damage, allowing healthcare providers to diagnose various liver diseases and conditions. During a liver biopsy, a small sample of liver tissue is extracted and examined microscopically. This examination can reveal the extent of liver damage, inflammation, fibrosis, or cirrhosis, providing crucial information about the liver's health and functioning. By identifying abnormalities in the liver tissue, clinicians can determine appropriate treatment options and monitor the progression of liver disease accurately.

Measuring bile acid levels, performing a gallbladder scan, or evaluating blood flow in the liver are all diagnostic processes important for specific conditions but do not serve the primary purpose of a liver biopsy, which focuses on directly analyzing liver tissue.
