- Urine ketones measure only acetoacetate (AA), and not ß-Hydroxybutyrate (ß-HB )
- a negative urine ketones dipstick makes DKA unlikely, but it is still possible to have DKA
with a negative urine AA ketones dipstick.
- a positive urine requires serum ketones assessment because serum and urine AA levels
can increase in fasting states, but serum ß-HB value will be < 3 mmol/L
