Office Breath Testing Instructions and Video

As of March, 2021, we have resumed limited in-office lactulose hydrogen-methane breath testing for certain patients.  Most new patients will be helped to do the home test for hydrogen, methane and hydrogen sulfide called trio-smart.  If that is what you are having, see the other page: Preparation and Instructions for Trio-Smart Breath Test using a home kit.

The SIBO lactulose breath test takes approximately 2 hours.  The testing in Fullerton will be on certain weekday mornings.  We will be using a process that will involve patients collecting the breath samples while in exam rooms, without staff present, to make this as safe as possible for both patients and our staff.

Fullerton address: 1837 Sunnycrest Drive, Fullerton, CA 92835

(in-office breath testing is not available in Mission Viejo at this time.)
