Healthflow Naturopathic has released a guide explaining SIBO (Small Intestinal Bacterial Overgrowth) breath test results, outlining diagnostic thresholds and clinical criteria. The guide defines a positive result as a hydrogen increase of 20 ppm or more within 90 minutes, or a methane level of 10 ppm or more at any point during testing. Aligned with North American Consensus guidelines, the resource provides reliable standards for those navigating complex gastrointestinal symptoms.

Because false-negative results occur in 20 to 30 percent of cases, accurate interpretation of breath test data is important, explains a representative for Healthflow Naturopathic. Imbalances may be missed when hydrogen sulphide-producing bacteria are present, intestinal transit is slow, or preparation protocols are skipped. These factors create diagnostic challenges that can delay appropriate care, making straightforward educational guidance critical for patient empowerment.
"Normal baseline readings should remain below 16 parts per million (ppm) for hydrogen before starting the test," explains Dr. Derek Cook, ND. "Higher baseline levels often signal improper preparation or existing bacterial overgrowth."
Dr. Cook distinguishes early gas elevation within the first 90 minutes as indicative of bacterial overgrowth in the proximal small intestine, rather than distal overgrowth or rapid gastrointestinal transit, noting the importance of correlating clinical presentation with an individual's symptoms and medical history.
To minimize errors, the publication details necessary test preparation protocols that prevent invalid or contaminated samples. Key instructions include a strict 12-hour fast, specific short-term dietary restrictions, and avoiding antibiotics for at least two weeks prior to the assessment. It also addresses how improper compliance can cause elevated baseline readings, which often reflect residual food fermentation rather than true bacterial overgrowth.
For individuals with positive results, the guide outlines common evidence-informed strategies, including low-FODMAP dietary adjustments and natural antimicrobial protocols using compounds such as berberine or oregano oil. Conversely, if symptoms persist despite a negative test result, the resource highlights alternative evaluation options such as functional stool analysis or serum antibody testing.
Founded in 2008 by Dr. Derek Cook, ND, Healthflow Naturopathic provides personalized, root-cause healthcare both in person in Calgary and virtually across Alberta. The complete educational guide is fully accessible to the public on the clinic's website.
