Breath gas test
SIBO - Breath Test for Analyzing Bacterial Fermentation Processes in the Small Intestine
Digestive trouble such as bloating, fullness or pressure in the abdomen? This breath test measures hydrogen (H₂) and methane (CH₄) in your breath and gives indications of bacterial fermentation in the small intestine.
No prescription needed. Ships the next working day.

Principle
Measure first, then decide
Without measured values, any treatment is guesswork. We turn the order around: the lab report first, then the decision.

ORY experts stay with you
Doctors and Heilpraktiker from the ORY team are there for you the whole way — with your lab report and with whatever follows.
What a value means, and whether a supplement is right for you, is something to discuss with a practitioner. This page makes no recommendation and is no substitute for medical assessment.
Details
What is in this analysis
What is measured
Hydrogen (H₂) and methane (CH₄) in breath gas across seven samples — indications of bacterial fermentation in the small intestine.
The biomarker reference explains what lies behind the numbers: how values interact, which cofactors are involved and which biochemical processes take place in the body — for all values and areas, not only this analysis.
To the biomarker reference
For whom
The SIBO breath test is suitable for bloating, abdominal pain and pressure, diarrhoea or constipation, a feeling of fullness, and brain fog and exhaustion that could be connected with an increased number of bacteria in the small intestine.
What a single value means in your situation is something you discuss with a practitioner. This does not replace medical assessment.
How it works
Four steps from order to lab report.
- 01 Kit arrives Ships the next working day, postage paid to your door.
- 02 Reference sample & test solution A fasting reference sample, then drink the test solution.
- 03 Measure breath gas Blow seven samples into tubes over 150 minutes.
- 04 Get your lab report 7–21 days after the sample arrives, consultation included.
Instructions
The key points first:
- Start on an empty stomach: reference sample (tube 1) before drinking the test solution.
- After drinking the test solution, blow into the tubes at set intervals up to 150 minutes.
- Send all tubes back together, labelled.
Please read the instructions carefully. Correct preparation matters: it is what allows your sample — stool, urine, saliva or blood — to be evaluated cleanly and meaningfully.

Sending your sample back
So your sample reaches the laboratory safely, please follow the rule for your country.
| Country | Postage | Shipping |
|---|---|---|
| Germany | Already paid | Return postage is prepared, you do not need to add a stamp. |
| Austria | Add your own postage | To our address in Vienna, not to Germany. |
| Switzerland | Add your own postage | Separate return bag for Switzerland, sent to Germany. |
| Rest of Europe | Add your own postage | Sent to Germany. |
In short: Germany is all set. Austria, add postage and send to Vienna. Switzerland, add postage, special bag, send to Germany. Rest of Europe, add postage and send to Germany.

Reimbursement by private health insurance
This is how it works with us if your private insurance may reimburse you:
Many private insurers cover the cost in full or in part – some not at all. That depends solely on your contract. We support you through the process as well as we can.
