Lactose Intolerance Test

The lactose breath hydrogen test can determine if you are lactose intolerant by measuring the amount of hydrogen produced after ingesting lactose. Hydrogen and other gases are produced when undigested lactose in the colon is fermented by bacteria.

You will be asked to drink 12 oz. of whole milk 3 hours before the test. A total of 2 breath samples will be taken over a span of about 15-20 minutes to determine if you are lactose intolerant.

Contact on of our Gastroenterology offices in Glendale or Valley stream to schedule your lactose intolerance test.
