Metabolic Solutions sells a collection kit that is shipped to the company's lab for analysis.sells SIBO test kits from Genova Diagnostics direct to patients, without requiring a prescription.Genova Diagnostics - Small Intestinal Bacterial Overgrowth test is a collection kit which is sent via FedEx courier to the company's lab for analysis.GastroCHECK is a desktop hydrogen and methane breath test machine which is available for use through some medical providers.Gastro+ is a handheld hydrogen breath test machine which available for use through some medical providers.Alternatively, breath samples may be collected using a kit then shipped to a remote lab for analysis. Testing may be done in-office or at home using portable, possibly even handheld, breath testing equipment. However, testing may be limited to measuring only hydrogen due to available equipment and/or cost considerations.Įvidence Subgroup Cost and availability Measuring the concentration of both gasses is ideal to ensure that both aerobic and anaerobic bacteria are detected. Test equipment may measure the concentration (in PPM) of hydrogen gas, methane gas, or both. (The idea is that this indicates two clusters of bacteria - one in the small intestine, and one in the large intestine.) (The idea is that an early rise must be from bacteria in the small intestine, as food would not have reached the large intestine yet.) Gas level rises above a certain threshold within a certain timeframe.SIBO may be indicated if one or both of the following criteria are met: The gas levels from each sample are measured and recorded, then typically plotted a on a line graph. The patient's breath is sampled periodically over the course of a few hours, typically every 15 to 30 minutes. In order to prevent results from being affected by food already in the digestive tract, the procedure continues only if the baseline gas levels are below a certain threshold.Ī small amount of Lactulose solution is consumed by the patient. Baseline gas levels are measured from the patients breath at the beginning of the test. The test is preceded by a 24-hour preparation period, which includes a limited diet and a period of fasting. Since food travels gradually through the small intestine before reaching the large intestine, the change in gas levels over time can indicate the location and population of bacteria.ĭiagnosis of SIBO via breath testing is controversial due to the species-dependent nature of breath tests and the lack of an agreed threshold for a positive test. Aerobic bacteria produce hydrogen gas, whereas anaerobic bacteria produce methane gas.īoth hydrogen and methane gasses produced by intestinal bacteria can be detected on a person's breath. Bacteria in the digestive tract produce gasses as a byproduct of food metabolism.
