Get an accurate SIBO Test

Many people experience discomfort and sometimes nausea due to SIBO, especially after a course of antibiotics or if they have an autoimmune issue that affects their gut health. Unfortunately, they often get misdiagnosed with IBS, which limits their treatment options. With our SIBO test kit, you can know whether you have SIBO and discuss your treatment options with your physician with all the information you need in hand.

Our SIBO Breath Test Process


Register or order

Schedule your SIBO test online and complete a brief registration form. Alternatively, order a test for home use.



This test requires the patient to take nothing by mouth (NPO) for 12 hours, avoidance of certain foods for 24 hours, and no smoking for at least an hour.


Get tested

Commit at least three hours for your SIBO test. If you test at home, make sure to follow the instructions carefully, as it can affect the accuracy of the test.


Get results

Get results the same day for in-office visits or within a day after your test has been received for at-home tests.

SIBO symptoms can mask as other conditions. Discuss testing options with your personal care provider.
