Test Overview
A ketone test
checks for
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
in your diet. But 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
can't use blood sugar (glucose) properly.
Some home blood sugar
meters can also measure ketone levels in the blood. Home
urine tests to measure ketones are available.
