Lactose Intolerance Breath Test
Updated over 3 months ago

Test Details

Lab Company: Aerodiagnostics
​Sample Type: Breath
​Collection Location: At Home

This test is used to help diagnose a condition called lactose intolerance. This condition occurs when the body cannot break down lactose (a sugar commonly found in dairy products) because the necessary enzyme is not present. When this happens, bacteria in the digestive system can produce gases like hydrogen and methane, which can cause symptoms like bloating, diarrhea, and flatulence.
