Glucose Hydrogen Breath Test Instructions

Gluclose Breath Test by Quintron

What is a glucose hydrogen breath test?
The glucose hydrogen breath test is used to identify abnormal growth of bacteria in the intestine. You will be asked to breathe into a breath collection device and your breath will be collected and analyzed for the presence of hydrogen.
Normally, small amounts of bacteria are found in the intestine. If there is a significant increase in the amount of bacteria, food and nutrients are not absorbed properly. Bacterial overgrowth can result from a slow transit of food through the bowels or from certain medications. Symptoms may include abdominal pain, bloating, gas, and diarrhea.

What are the possible complications with this test?
Complications of a glucose hydrogen breath test are rare.

What should I expect during the test?
First, you will collect a baseline breath sample by breathing into the collection device. Then you will drink a solution of glucose. Then, every 20 minutes for a 3 hour period, you will breath into the device. You will collect a total of 10 breath samples.

What should I expect after the test?
Breath test samples must be returned/mailed 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. If the test indicates that you do have small bowel bacterial overgrowth, it may be treated with antibiotics.
