Ketones

Test Overview
A ketone test checks for ketones in your blood or urine. Ketones are substances that are made when the body breaks down fat for energy. Normally, your body gets the energy it needs from carbohydrate in your diet. However, stored fat is broken down and ketones are made if your diet does not contain enough carbohydrate to supply the body with sugar (glucose) for energy or if your body cannot use blood sugar (glucose) properly.
Newer home blood sugar meters can also measure ketones. Home urine tests to measure ketones are available.
