This test cannot be used to diagnose congenital disorders of galactose metabolism, but only for patients with liver disease. Human tissues cannot directly use exogenous galactose, and it needs to be converted to liver glycogen by the liver before it can be used. Hepatic parenchymal damage (acute hepatitis, cirrhosis, cancer metastasis to the liver, etc.) impairs galactose conversion and impairs tolerance. Hypothyroidism and impaired tolerance.
