Small intestinal bacterial overgrowth (SIBO) is still labeled a “GI diagnosis,” but your SIBO patients live in endocrine, allergy, rheum, and primary care clinics as well as yours. This first article in the Beyond the Gut series is written for you as a gastroenterologist. The goal is simple: show how hypothyroidism links to SIBO, why that matters…
Sample stability is a crucial factor directly impacting the accuracy and reliability of hydrogen and methane breath testing results. Ensuring that samples remain stable throughout collection, storage, and transportation is essential for maintaining the integrity of the breath test, which detects conditions such as Small Intestinal Bacterial Overgrowth (SIBO), Intestinal Methanogen Overgrowth (IMO), and carbohydrate…
CO2 correction is a vital component of accurate hydrogen and methane breath testing, and at CDI, we lead the way in implementing this essential process. By choosing CDI, healthcare providers can trust that they receive the most accurate, reliable, and transparent diagnostic results, enabling them to deliver exceptional patient care. Breath testing has become a…
A recent study and editorial in The American Journal of Gastroenterology (AJG) revisit a question that sits at the heart of modern functional GI care: When patients with disorders of gut–brain interaction (DGBI) say they’re “intolerant” to certain carbohydrates, how often is that backed by objective malabsorption—and does it matter clinically? The answer from this work: carbohydrate malabsorption…
Hydrogen and methane breath testing plays a critical role in diagnosing functional gastrointestinal disorders such as SIBO, IMO, and carbohydrate malabsorption. A breath test is ordered to answer a specific clinical question and guide next steps in patient care. When a test is never completed or returned, that diagnostic pathway stops short. Unreturned or unregistered…
Hydrogen and methane breath testing has become a staple in diagnosing conditions like Small Intestinal Bacterial Overgrowth (SIBO) and Intestinal Methanogen Overgrowth (IMO). While effective, understanding the sensitivity and specificity of these tests is critical for interpreting results accurately. This article in our ongoing Breath Testing Done Right series delves into how sensitivity and specificity…
A newly published study from Swedish clinical researchers further confirms the diagnostic value of hydrogen and methane breath testing (HMBT) for Small Intestinal Bacterial Overgrowth (SIBO)—supporting the core science behind CDI’s non-invasive testing model. The 2025 study, Refined Lactulose Hydrogen Breath Test for Small Intestinal Bacterial Overgrowth Diagnosis Based on a Survey Among Experts, analyzed data from…
As functional GI disorders, such as Small Intestinal Bacterial Overgrowth (SIBO), Intestinal Methanogen Overgrowth (IMO), and carbohydrate malabsorption, continue to challenge clinicians due to symptom overlap and diagnostic ambiguity, new research underscores an important truth: symptoms and history alone are not reliable predictors of breath test outcomes. A large-scale 2024 study conducted by our research…
As practices across the country continue to adopt non-invasive hydrogen and methane breath testing to improve diagnostic accuracy for functional gastrointestinal conditions, one performance metric is proving especially critical to clinical and operational success: the test return ratio. The short answer Return ratio is the percentage of breath test kits sent out that come back…
