Making the Diagnosis
The amount of ketones in the urine should be checked if a person with diabetes has:
- symptoms of DKA
- fasting blood glucose levels above 14 mmol/L (252 mg/dL) for 24 hours
- an infection or illness
Ketone levels can be easily measured at home; a positive test requires immediate medical attention. A doctor or health care professional can show you how to measure the amount of ketones in your urine.
