About Ketone Monitors

Last checked September 28, 2026

Ketone Monitors is an independent guide to continuous ketone monitors and the blood, breath and urine tests they sit alongside. The first continuous ketone sensor was authorized by the FDA in August 2026, and facts about what is on sale, where and at what price are scattered across press releases, shops and journals. We gather them in one place, with a source for each.

We are not a medical site and are not linked to any device maker. We report product facts and published research; we don’t give medical advice, and we have not tested the devices ourselves.

How we work

Every figure on this site comes from a source we link to: the maker, the regulator, the government or published research. We check pages regularly and show the date each one was last checked at the top. If you spot something wrong or out of date, email [email protected] and we'll fix it.

We don't accept payment to change what we say about a product, and we never claim to have tested something we haven't.
