Breath gas test
Lactose Breath Test
Detect lactose intolerance reliably — no blood draw, no doctor's visit. Hydrogen (H₂) and methane (CH₄) in your breath show exactly whether your body can process milk sugar.
No prescription needed. Ships the next working day.

The principle
Measure first, then decide
Without measured values, any treatment is guesswork. We turn that around: the lab report first, the decision after.

Ory experts are there for you
Doctors and non-medical practitioners (Heilpraktiker) from the Ory team are with you all the way — for the lab report and everything after.
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.

What this analysis covers
What is measured
Hydrogen (H₂) and methane (CH₄) in your breath at five time points over three hours — shows whether lactose is properly absorbed 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
Who it's for
The lactose breath test suits bloating, stomach cramps, diarrhoea or a feeling of fullness after dairy, and irritable bowel symptoms whose cause is unclear.
What a single value means for you is something to discuss with a practitioner. This does not replace a medical assessment.
How it works
Four steps from order to lab report.
- 01 Kit arrives Sent the next working day, postage paid, to your door.
- 02 Drink the lactose solution After the baseline reading, drink the lactose solution supplied.
- 03 Measure your breath Blow into a tube at 5 time points (0, 30, 60, 120, 180 min).
- 04 Receive your lab report 7–21 days after the sample arrives, consultation included.
Instructions
The main points first:
- Start on an empty stomach and take the baseline reading before drinking the lactose solution.
- After drinking it, blow into a tube at 30, 60, 120 and 180 minutes.
- Label all 5 tubes and send them in together.
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 that 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 | Pay postage yourself | To our address in Vienna, not to Germany. |
| Switzerland | Pay postage yourself | Separate return bag for Switzerland, sent to Germany. |
| Rest of Europe | Pay postage yourself | Sent to Germany. |
In short: Germany, nothing to do. Austria, add postage and send to Vienna. Switzerland, add postage, use the special bag, send to Germany. Rest of Europe, add postage and send to Germany.
