Useful For
The test measures ketone levels in your urine. Normally, your body burns glucose (sugar) for energy. If your cells don’t get enough glucose, your body burns fat for energy instead. This produces a substance called ketones, which can show up in your blood and urine. High ketone levels in urine may indicate diabetic ketoacidosis (DKA), a complication of diabetes that can lead to a coma or even death.
