# Blood Ketones (`bloodKetone`)

## Quick Summary

## Type (`type`)

Blood ketones represent ketone concentration values (specifically beta-ketones) obtained from a fingerstick meter capable of reading specialized blood ketone testing strips. Tidepool does not yet provide a data model for urine ketones, which are measured qualitatively, not quantitatively.

## Value (`value`)

Tidepool has used the most popular blood ketone meter on the American market — the Abbott Precision Xtra — as a guide to choose 10.0 mmol/L as the maximum value that will be accepted by Platform. (The Abbott Precision Xtra yields HI for blood ketone values higher than 8.0 mmol/L.)
