Glucose and lactulose BTs remain the least invasive alternatives to diagnose SIBO. Consensus doses for lactulose, glucose, fructose and lactose BT were 10, 75, 25 and 25 g, respectively. Using an evidence-based approach, 28 statements were finalized and voted on anonymously by a working group of specialists.Ĭonsensus was reached on 26 statements encompassing all five domains. Pre-meeting survey questions encompassing five domains indications, preparation, performance, interpretation of results, and knowledge gaps, were sent to 17 clinician-scientists, and 10 attended a live meeting.
