What it is
The Ketoscan Mini, made in Korea, measures acetone in the breath in parts per million (0 to 99 ppm). A test takes about 5 seconds after the meter warms up, and the sensor cartridge lasts about 300 tests before it is replaced (Bodyketosis, Home Health UK). The maker claims an error of ±0.5 ppm below 5 ppm and ±10% above.

Limitations of breath testing
- Breath acetone is a different ketone from the beta-hydroxybutyrate that blood meters and sensors read, and the numbers are not in mmol/L.
- Studies show breath acetone is only moderately correlated with blood ketones, and metal-oxide sensors can react to other gases and drift (Fante et al., 2025).
- Breath ketone meters have no FDA clearance for diagnosis; one study found a link with blood readings in adults but not in children (Huang et al.).
