The SIBO Breath Test Hydrogen & Methane - Lactulose by Nutripath is designed to assess small intestinal bacterial overgrowth (SIBO) through measurement of hydrogen and methane gases produced after ingestion of lactulose. This non-invasive breath test helps gather valuable information by analysing gases exhaled over a specific period. It guides healthcare providers in understanding digestive health and microbial activity in the small intestine. The test is simple, requiring only breath samples at timed intervals following lactulose intake. It's an important tool used by practitioners to support gut health evaluations.
