Thank you for your question. We actually did not test via the breath test in our clinical trials. Instead, we used the criteria that Xifaxan used in their clinical trials and focused on clinical improvement of symptoms. The reason for this is because the breath test can be very inaccurate at times. Using symptomatic improvement in our clinical trials we had over 88% improvement. We hope this helps to answer your question. Please let us know if we can be of further assistance.
Thank you and best wishes,
Support Team
