Fructose intolerance can be diagnosed with a liver biopsy, which tests a small part of the liver for the absence of the enzyme that helps your body process fructose. Doctors also determine the extent of possible liver damage with this test. Your doctor can also use a fructose tolerance test. Both tests are invasive and can be risky for young children. As an alternative, your doctor may recommend a DNA test to diagnose fructose intolerance.
