Lactose Malabsorption Breath Test

About the Test

This test is used to help diagnose lactose malabsorption. Lactose malabsorption may occur when the enzyme needed to break down lactose, a sugar commonly found in dairy products, is not present. The lack of the enzyme allows bacteria normally found in the digestive system to produce hydrogen and/or methane gas which can cause many gastrointestinal symptoms such as bloating, diarrhea, and flatulence.
