GIT Lactulose Breath Test (SIBO)
An at-home breath test that checks for small intestinal bacterial overgrowth (SIBO).
Why You Should Take This Test
If bloating occurs soon after eating, this breath test can provide data your provider may use when evaluating whether SIBO could be contributing.
Who It's For
Anyone with bloating, gas, or digestive discomfort that seems tied to specific meals.
Benefits
- Measures breath gases used by providers when evaluating possible small intestinal bacterial overgrowth.
- Non-invasive -- just breathe into a series of at-home collection tubes.
- Offers a non-invasive way to screen for breath patterns that may be consistent with SIBO.
