Fructose Intolerance / Fructose Malabsorption Breath Test

Fructose, or fruit sugar, is a naturally occurring sugar that is used as a sweetener in many foods, including many baby foods. Man-made fructose is also used as a sweetening ingredient in many foods.

Individuals with fructose intolerance may experience severe abdominal pain, bloating, diarhhea or constipation after ingesting food or drinks containing this sugar. These painful symptoms may be greatly diminished if fructose intolerance is detected, and an appropriate dietary regimen is followed.

How to prepare for the Fructose Intolerance Breath Testing?

There is a 24-hour preparation period before taking the test; the first 12 hours require a specific diet, and the last 12 hours require a complete fasting period; however, you may brush your teeth.

How the Fructose Intolerance Breath Testing program works:

  • The test is performed, in the physician's office or the patient's home
  • Breath samples are returned to Commonwealth Laboratories LLC in the postage paid box.
  • The analytical results are faxed to the physician's office
