How is fatty liver disease diagnosed?

If your doctor thinks you may have fatty liver disease, he or she may order the following tests:

  • Blood tests to check for higher levels of certain liver enzymes.
  • An ultrasound or computed tomography (CT) scan of the liver to check for abnormalities and confirm the diagnosis of fatty liver disease.
  • A liver biopsy (tissue sample) if your doctor suspects that you have severe liver disease.

Elastography is a newer technique that uses waves transmitted by ultrasound, magnetic resonance imaging (MRI) or vibration (Fibroscan) to estimate the amount of steatosis (fat) and fibrosis (stiffness) of the liver without taking a biopsy.
