Term Description

The hydrogen breath test is based on the fact that the only hydrogen gas source in humans is intestinal bacteria, which produces hydrogen gas during carbohydrate metabolism. After the patient ingests a dose of fructose, any carbohydrate that is not absorbed is metabolized by intestinal bacteria During this process, hydrogen gas is produced, which is absorbed and eventually exhaled through the lungs; the amount of hydrogen in the expired gas is measured at various intervals depending on the protocol being used. The test is used to detect fructose malabsorption, irritable bowel syndrome and small intestine bacterial overgrowth. PMID: 16474100

Part Description

LP183612-3   Fructose challenge panel
Hydrogen breath test using fructose is performed to diagnose a fructose malabsorption. A pre dose reading of hydrogen levels is collected. The patient is then given a small amount of fructose, and then required to take readings every 15, 30 or 60 minutes for two to three hours. The basis of the test is a failure to absorb the given sugar, which is then metabolized by bacteria that give off either hydrogen or methane. Therefore, the more gas that is produced, the less absorption has occurred. If the level of hydrogen rises above 20 ppm (parts per million) over the lowest preceding value within the test period, the patient is typically diagnosed as a fructose malabsorber. If the patient produces methane then the parts per million for the methane typically rises 12 ppm over the lowest preceding value to be considered positive. If the patient produces both hydrogen and methane then the values are typically added together and the mean of the numbers is used to determine positive results, usually 15 ppm over the lowest preceding value.
