Worth noticing
It separates beta-hydroxybutyrate, acetone and acetoacetate readings, noting that their numbers cannot be converted into each other.

Field notes

The guide distinguishes four test formats by sample, units and frequency, and warns that their readings are not interchangeable. Its calculator compares recurring strip or breath-test costs with a sensor’s fixed monthly cost; the displayed example uses UK prices checked on September 28, 2026. The page also separates devices available now from an authorized sensor that it says is not yet on sale.
