FREQUENTLY ASKED QUESTIONS
What is trio-smart?
trio-smart is a mail-in breath test that aids in the diagnosis of small intestinal bacterial overgrowth (SIBO), intestinal methanogenic overgrowth (IMO) and excess hydrogen sulfide. trio-smart is the only three-gas breath test that measures all of the primary fermented gases produced in your gut: hydrogen, methane, and hydrogen sulfide. Breath samples can be collected in the comfort of your own home. Data from trio-smart can help you and your provider determine the best course of treatment for you.
How do I know if trio-smart is right for me?
If you experience any of the following symptoms once a week or more for at least four weeks, then trio-smart could provide you with answers about your GI symptoms: bloating (especially after eating), gas, diarrhea and/or constipation.
What does trio-smart detect?
The trio-smart breath test measures the three primary fermented gases produced in your microbiome. The gases measured are hydrogen, methane, and hydrogen sulfide.
Hydrogen is produced when certain bacteria consume sugars.
-
Hydrogen levels are considered abnormal when they rise greater than 20 ppm (parts per million) from the baseline within 90 minutes.
-
Abnormal levels of hydrogen are indicative of small intestinal bacterial overgrowth (SIBO).
Methane is produced when archaea (single-celled organisms similar to bacteria) consume hydrogen.
-
Methane levels are considered abnormal if they reach ≥10 ppm (parts per million) at any point during the breath test.
-
Abnormal levels of methane are indicative of intestinal methanogenic overgrowth (IMO).
Hydrogen sulfide is produced when hydrogen sulfide producing organisms consume hydrogen.
-
Hydrogen sulfide levels are considered abnormal if they reach ≥3ppm (parts per million) at any point during the breath test.
-
Abnormal levels of hydrogen sulfide are indicative of excess hydrogen sulfide.
How accurate is trio-smart?
trio-smart measures the levels of gases in your breath and adheres to the thresholds laid out in the North American Consensus for breath testing. trio-smart is incredibly precise with the gas measurements it provides. Conventional breath testing has a detection sensitivity of ±2 ppm. The trio-smart device had a detection sensitivity of ±0.1 ppm, significantly minimizing the rates of false negatives/positives.
Do I need a doctor to order trio-smart for me?
trio-smart is a doctor-ordered test. You can order trio-smart by working with a doctor online. Results are delivered directly to you within seven business days. trio-smart can also be ordered directly through your healthcare provider.
