HOW IT WORKS

SIBO Breath Test - how it works

Step #1 - Order the Test Online

Order your at-home SIBO test kit from the IFDW online shop. You will receive it within 2-5 business days. Ensure you carefully read the detailed instructions on how to prepare.

Step #2 - Perform The SIBO Test At Home

Here’s how to use this home SIBO test kit:

First, take a baseline measurement to determine the amount of Hydrogen and Methane in your small intestine. Then, dissolve the glucose provided in the test kit with water and drink it.

Breathe into the test tube every 20 minutes for 3 hours (nine samples in total). These samples help the lab measure hydrogen, carbon dioxide, and methane spikes in your breath and accurately detect SIBO.

Important! Our lab will diagnose SIBO if your breath contains 20 parts per million (ppm) of hydrogen gas or 10 ppm of methane gas.

Step #3 - Send Your SIBO Test to the Lab (FREE)

Return your breath samples to the IFDW lab using the prepaid shipping label. Delivery is free.

Step #4 - Get Detailed, Personalized Results Within 24-72 Hours

Once your breath samples arrive, you’ll receive detailed results within 24 hours (longer if submitted during the weekend).

Optional: Get Your Results Explained by A SIBO Expert (downloadable Video)

For deeper clarity, you can add a professionally recorded, personalized video where a qualified SIBO expert walks you through your results. Tailored to your individual test.

It’s like having an expert in your corner. Available anytime, on your schedule.

Some of the reviews shown are from related products the merchant grouped with this one.

Well, the test is good. The instructions are good. The test showed up very quickly. Problem was it showed up in two days but it took over a week to get shipped to them because they do a cheap ground shipping and then they say you have results in 24 within 72 hours and that’s not true either so I’d say the test is fine but the facility and company needs to do better with their shipping label and their turnover result time
