EventsThe First Disposable Breath Ketone Test Has Arrived
in Ketone measuring 
The Metron breath ketone test
Do you want a simple way to check for ketosis, without a urine or blood test? It’s also possible to check you breath for ketones (acetone). This has already been possible for some time with the Ketonix reusable breath analyser (costing $149).
Now the Ketonix is joined by the just-launched disposable test Metron, which can be ordered via Amazon ($28 for 10 tests).
Metron is cheaper if you only want to do a few tests (up to 50 tests), but the reusable Ketonix is cheaper if you want to do more tests than that – testing is free once you have one.
At some point we may do a test of Ketonix vs. Metron. Would you find that interesting? Or do you already have your own experience comparing these two devices? Please leave a comment.
My own meter for success is my Mirror ;).
Since the blood & urine ketone tests measure different substances, why should they correlate or be the same? Many people have this expectation, which has no current scientific basis, and it seems to be one of many myths around ketosis. Your body uses the two ketones differently for different purposes & becomes more efficient with them over time. So again, why should they be equivalent or related? Would really love to hear your science on this, if you have some new insight. Thanks.
No Andreas, I don't think a comparison will be useful - it's like comparing a hacksaw to a cocktail shaker, really. They do different things on different substances. :D Best wishes. (I live at about 4.2 on the blood meter BTW, with lows of about 2.1)
And the Ketonix is astronomically cheaper than ketone strips. Only Type 1s who have to check they are not going into acidosis use those.
Both devices claim to measure breath acetone. You seem to be have confused metron with blood and urine tests.
