What do I need to do to prepare for the test?.If choosing this kit, please be aware that you will need to collect samples on 3 different days for each of the 3 different substrates. To be most certain that you do not miss the diagnosis of SIBO, the SIBO COMPREHENSIVE test kit is best. Testing with glucose and/or fructose in addition to lactulose will cast a larger net and increase the chances of detecting SIBO if it exists. If opting for a single substrate, lactulose is the best option. Mark Pimental, of Cedars-Sinai Hospital in Los Angeles. This test is widely used in the United States to diagnose SIBO and is used as a stand-alone test by leading excerpt, Dr. SIBO BASIC is a single test using lactulose as the substrate.If you are a patient and choose to order a test kit directly from our website without practitioner pre-approval, you will be given the option to name your practitioner so that they will receive your test results. However, we strongly recommend that you work with a practitioner to interpret your results and determine a plan of action. Practitioner pre-approval is not required for SIBO breath tests ordered within Australia.Do I need a practitioner to order a breath test?.Testing is also helpful to identify whether or not SIBO has been eradicated after treatment to determine the best next steps. Testing is the only way to know if you truly have SIBO and what therapies are appropriate. Treating for SIBO without testing could cost you time and money on unnecessary supplements, medications, and strict dietary protocols.Why should I test instead of just treat for SIBO?.We use only genuine QuinTron test kits and QuinTron BreathTracker technology, which is considered the gold standard for SIBO testing. Our extensive quality control includes carbon dioxide measurements to assure an acceptable alveolar air sample and frequent calibration of testing machines. At SIBO Test, we comply with the highest standards of analytical excellence. The more substrates you test with, the more reliable your results will be. Breath testing for SIBO is the widely used test to diagnose SIBO because of its convenience and low cost.How reliable are SIBO Test breath tests?. ![]() Breath samples are measured for hydrogen and methane to determine if there is small intestinal bacterial overgrowth (SIBO). These are diffused into the bloodstream and exhaled via the breath. The bacteria ferment the test substance and produce hydrogen and/or methane. ![]() ![]() These substances are not absorbed and therefore act as a food source for bacteria in the small intestine. After a 24-hour preparatory diet, the substrate (lactulose, glucose, or fructose) is swallowed. The breath test is a simple, non-invasive test.Diagnostic accuracy of hydrogen breath testing in SIBO can be maximized by careful patient selection for testing, proper test preparation, and standardization of test performance as well as test interpretation. The measurement of methane in addition to hydrogen can increase the sensitivity of breath testing for SIBO. Lactose, fructose, and sorbitol should not be used as substrates in the assessment of suspected SIBO. Carbohydrates such as lactulose and glucose are the most widely used substrates in hydrogen breath testing, with glucose arguably providing greater testing accuracy. Although not without shortcomings, hydrogen breath testing provides the simplest noninvasive and widely available diagnostic modality for suspected SIBO. The current gold standard, small-bowel aspiration and quantitative culture, is limited by its high cost, invasive nature, lack of standardization, sampling error, and need for dedicated infrastructure. Unfortunately, no perfect test exists for the diagnosis of SIBO. Ideally, an accurate and objective diagnosis of SIBO should be established before initiating antibiotic treatment. The diagnosis of small intestinal bacterial overgrowth (SIBO) has increased considerably owing to a growing recognition of its association with common bowel symptoms including chronic diarrhea, bloating, abdominal distention, and the irritable bowel syndrome.
