What is a fructose breath hydrogen test?
This is test can determine if you have a problem digesting fructose products. Symptoms of fructose intolerance include diarrhea, gas, cramping, and bloating. Fructose is a naturally occurring simple sugar found in fruit, vegetables, and honey. When fructose is combined with the normal bacteria in the intestine, hydrogen gas is expired as you breathe. You will be asked to breathe into a breath collection device and your breath will be collected and analyzed.

What are the possible complications of this test?
This test is very safe. You may feel minor discomfort from diarrhea, gas, cramping or bloating. Notify your doctor if you have an allergy to fructose.

What should I expect during a fructose breath hydrogen test?
First, a baseline breath sample will be obtained by breathing into the device. Then you will drink a fructose solution. After drinking the solution, you will wait 1 hour between each breath sample. You will collect a total of 4 breath samples. You should allow 3 hours for the test.

What should I expect after the test?
You must return/mail the kit within 3 days of collection. You will be able to resume your normal activities and diet. Your doctor will send you the results by mail in 9-12 days after your test is received.
