This simple at-home breath test measures hydrogen and methane levels to identify lactose intolerance.
This straightforward breath test is a simple way to confirm or rule out the presence of lactose intolerance.
In healthy individuals, lactose is broken down and absorbed, so little to no increase in breath hydrogen is observed. When lactose intolerance is present, breath hydrogen increases – sometimes patients are lactose intolerant but their breath hydrogen doesn’t increase, because it’s converted to methane.
Our test records and compares breath samples taken after fasting, and after drinking a lactose solution, measuring the presence of hydrogen and methane to assess lactose intolerance.
