SIBO Breath Test: investigate hydrogen and methane patterns behind persistent gut symptoms
A non-invasive at-home breath collection for bloating, gas, constipation, diarrhea, and other patterns that may warrant evaluation for SIBO or intestinal methanogen overgrowth.
This may be worth exploring if...
These are common reasons someone may ask the Nuvitru team whether a SIBO breath test fits the next question.
Why specialty testing is different
Normal is not the same as optimal, and a test is not the same as interpretation.
The report is only the beginning
Genova's SIBO profile is a non-invasive breath test that measures exhaled hydrogen and methane after a lactulose solution to help evaluate patterns associated with small intestinal bacterial overgrowth or intestinal methanogen overgrowth. Results require clinical context and are not a standalone diagnosis.
Use the lab menu to match your symptoms and goals to the panel that fits the question.
Pricing reflects the lab test only; assessment and interpretation are purchased separately.
When results return, they are uploaded to your patient portal and our team texts you.
Purchase a new patient session or join a care plan to connect the dots and decide next steps.
Is this the right test for you?
A good fit if...
Persistent bloating, gas, constipation, diarrhea, or abdominal discomfort
Your practitioner wants to evaluate SIBO or intestinal methanogen overgrowth patterns
You can follow the preparation diet, fasting, and timed collection instructions
You want results interpreted alongside symptoms, history, and other gut data
Maybe not the right fit if...
You need emergency or urgent care
You want a diagnosis or treatment without a clinician evaluation
You want the lab alone to create your plan
A different test may be a better first step for you
What is included
Questions patients ask before ordering
What does the Genova SIBO test measure?
It measures hydrogen and methane in timed breath samples after a lactulose solution. Those gas patterns can help a qualified practitioner evaluate for SIBO or intestinal methanogen overgrowth in clinical context.
Is the collection done at home?
Yes. The kit uses a preparation diet, overnight fasting, and a specific timed breath-collection technique. Follow the kit instructions closely and confirm medication or supplement preparation with your practitioner.
Does this test diagnose SIBO by itself?
No. Breath-test biomarkers may suggest a pattern worth evaluating, but results should be interpreted with symptoms, history, and clinician judgment.
How do I order the SIBO test through Nuvitru?
Email hello@nuvitru.com. The team will confirm the appropriate profile, current patient price, availability, and ordering steps.
Is this a diagnostic test?
No. It is an educational and clinical decision-support tool. It highlights patterns to explore with a practitioner and does not, on its own, diagnose or treat any condition.
How long do results take?
Most results return about 2-3 weeks after the lab receives your sample. Timing can vary, and we confirm current turnaround before fulfillment.
Do I need to stop supplements or medications?
Sometimes. Certain supplements or medications can affect specific markers, so we send prep instructions and confirm what to pause. Never stop a prescription without your prescriber's guidance.
Can I order this without becoming a patient?
Yes, you can order without officially becoming a patient, but the care plan is where the magic happens. We encourage you to at least schedule a new patient session to get the most out of your results.
What happens after results come back?
We upload them into your patient portal and send you a text to let you know it has been uploaded. You can text our care team to schedule your new patient session if that is something you're wanting to do.
What if this is not the right test for me?
That is why choosing the right test matters. We can redirect you toward a better first step before a kit ships or a draw is arranged.
Start with data, leave with a plan.
