Small Intestinal Bacterial Overgrowth (SIBO) Test

Quick Description:Genova's SIBO Profile is a non-invasive breath test that captures exhaled hydrogen (H2) and methane (CH4) gases following patient ingestion of a lactulose solution to evaluate bacterial overgrowth of the small intestine. 


Recommended for:

  • Gastrointestinal symptoms
  • IBS / IBD
  • bloating
  • abdominal distention and pain
  • diarrhea
  • flatulence
  • Headaches
  • Autoimmune disease
  • Inflammation
  • Brain fog
  • Skin problems


SIBO is a common clinical condition and can develop in a variety of patient populations.

Risk factors for development of SIBO include structural/anatomic issues, motility disorders, organ system dysfunction, elderly age and various medications (recurrent antibiotics, PPIs) that alter the gut microflora populations.


Genova's SIBO profiles reflect the current state of scientific understanding related to SIBO breath testing and results interpretation – and are designed to optimize management of the symptomatic patient. The 3-hour SIBO profile provides insight into gas levels over a longer period of time, and is recommended for patients with slower gastrointestinal transit or constipation.
