A ketone urine test measures the amount of ketones in the urine.
Before the test, your doctor will ask you to stop some medications that can affect the test result. If your doctor ask you to take a special diet, please follow the advice.
The test sample is normal urine.
A negative test result is normal.
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results.
An abnormal result means you have ketones in your urine. The results are usually listed as small, moderate, or large as follows:
- Small: <20 mg/dL
- Moderate: 30 to 40 mg/dL
- Large: >80 mg/dL
Urine ketones can be done at home. You may get the test kit from a drug store. The kit contains dipsticks coated with chemicals that react with ketone bodies. A dipstick is dipped in the urine sample. A color change indicates the presence of ketones. Since normal test result is no presence of ketones in urine, as long as you see the color change, it means abnormal.
