# No methane across multiple tests or users

### No methane across multiple tests or users


Seeing no methane across several tests - even when different people are testing - can be completely normal. Not everyone produces methane at detectable levels, and methane may not always be captured within the testing window.

A single test provides only a snapshot. Testing consistently over time helps each person establish their natural baseline and identify trends in response to diet and lifestyle.

If the results still seem unexpected, confirm that the testing instructions were followed correctly and contact our support team. We can investigate your concerns, but remember that it can be perfectly normal not to see methane in every breath reading.
