galactose breath test

galactose breath test

a breath test of liver function, in which the fasting subject is administered a dose of galactose labeled with carbon 13 and levels of labeled carbon dioxide in the breath are measured at specific time intervals. Low levels of carbon dioxide indicate that the galactose is not being metabolized properly, indicating either an enzyme deficiency or liver dysfunction, such as the fibrosis accompanying hepatitis.
