Ketones

Why It Is Done

A blood test is the most accurate method of measuring ketones. It is recommended for all people with diabetes whenever symptoms of illness are present, such as nausea, vomiting, or abdominal pain. These symptoms are similar to symptoms of high blood sugar and may mean you have diabetic ketoacidosis, a potentially life-threatening condition.

A urine test is the most commonly used method of measuring ketones. But it is less accurate than a blood test. It may be done to:

  • Monitor a person on a very low-carbohydrate diet.
  • Monitor a pregnant woman who has diabetes or has developed gestational diabetes.
