What Is a Fatty Liver?
7. Liver Biopsy
The most assured way of verifying a diagnosis of NAFL or NASH is through a liver biopsy. This is an invasive test that involves collecting a sample of liver tissue for examination. It is done by a doctor who will use a needle to secure a sample.
Because this involves piercing into an organ, the patient will likely suffer some pain. A local anesthetic is usually administered during biopsies for the patient’s comfort. The less invasive way to get a diagnosis would be an ultrasound. Some ultrasounds can be detailed enough to determine the level of fat and scar tissue the liver has suffered.
