SIBO/IBS Test
Lab-grade testing from the comfort of home. We ship a sterile self-collection kit with prepaid return shipping. Your sample is analyzed by a CLIA-certified laboratory partner and detailed results are delivered to a secure portal within 3–5 business days — no prescription, no clinic visit required.
Why take this test
The SIBO/IBS Test Kit with this device provides real-time breath testing to measure hydrogen and methane gas levels, which are key indicators of digestive fermentation and bacterial overgrowth. Through systematic food tracking and breath testing, you'll receive personalized insights into which foods trigger your symptoms and how your digestive system processes different nutrients. The comprehensive testing protocol helps identify SIBO, IBS patterns, and FODMAP sensitivities by monitoring your body's response to various foods over time. With the FoodMarble app, you'll get immediate feedback on your fermentation levels, dietary recommendations tailored to your unique digestive profile, and the ability to track symptom patterns to optimize your gut health and reduce digestive discomfort.
