We are the only lab to to offer Lactulose breath testing as the sole tests to help you diagnose SIBO. Other labs use Glucose as the only diagnostic test sugar and Lactulose as the control sugar.
See below as to why we think glucose is not the best substrate to diagnose SIBO. Using glucose only as the test substrate can miss many SIBO positive cases.
Lactulose breath testing for the diagnosis of SIBO is widely used by medical practitioners in the USA. Dr Mark Pimentel, Director of the Motility Program in the Gastroenterology Department of Cedars-Sinai Hospital in Los Angeles, uses this test exclusively to diagnose SIBO. He currently has done over 19,000 Lactulose breath tests and believes this test has a high level of accuracy when interpreted correctly. He is the author of “A new IBS solution” and considered the foremost expert on SIBO.
A double-blind randomized study* revealed that 84% of IBS patients exhibited bacterial overgrowth based on lactulose breath testing.

Glucose is an additional substrate for bacteria. It is absorbed in the first part of the small intestine. If positive, Glucose can give an additional confirmation of SIBO. The drawback to the glucose test is that glucose is quickly absorbed and therefore sometimes misses bacterial overgrowth further along in the small intestine. Some practitioners nd the combined use of lactulose and glucose for diagnosing SIBO more accurate.
This test leaves no stone unturned! This triple approach shines the brightest light and has the highest likelihood of finding fermentation and gas production if it is present. Additionally, if your test is positive for SIBO, it can let you know if fructose needs to be avoided during the treatment diet. If you have severe symptoms, it is advised to do this combination test to help guide dietary recommendations.
For those not suspected of having SIBO, but are experiencing symptoms with consumption of fruit, honey, and other fructose containing foods.
The breath test is a simple, non-invasive test. After a 24 hours preparatory diet, the lactulose (or glucose or fructose) test substrate is swallowed.
Lactulose is not absorbed and therefore acts as a food source for bacteria, if present, in the small intestine.
The bacteria ferment the testing substance and produce hydrogen and/or methane. These are diffused into the bloodstream and exhaled via the breath.
Breath samples are collected every 20 minutes for 3 hours. A third gas, hydrogen sulphide, can also be present but cannot be assessed via breath testing at this time.
All our tests use machines from QuinTron, the original manufacturer of BreathTracker, to measure both hydrogen and methane in a single sample of breath (alveolar air)
Testing for SIBO using the QuinTron BreathTracker is considered gold standard.
Extensive quality control, including carbon dioxide measurements to assure an acceptable alveolar air sample, comply with the highest standards of analytical excellence.
Watch this short video about why it's important to test, and not just treat, for SIBO.
24 hours (48 hours if you are constipated) before you start the test, you MUST restrict certain foods. You must also avoid certain medications and supplements for a minimum of 1 week.Please download and read the preparation instruction booklet
