What is this test?

The urine acetone test detects the presence of acetone and other ketone bodies in your urine. Ketones are produced when your body breaks down fat for energy instead of using glucose. Normally, ketones are present in very small amounts, but elevated levels can indicate certain medical conditions.

Why do I need this test?

Your doctor may order this test to: monitor diabetes control and check for diabetic ketoacidosis (a serious complication), evaluate unexplained weight loss, check for fasting or starvation ketones, monitor people following ketogenic diets, or investigate symptoms like frequent urination, excessive thirst, or fruity-smelling breath.

How is the test done?

A urine sample is collected in a clean, sterile container. You may be asked to collect a 'clean-catch' sample by cleaning the genital area before urination and collecting the middle portion of the urine stream. The sample is then tested in a laboratory using chemical strips or instruments that detect the presence of acetone.

What do the results mean?

Results are typically reported as 'Positive' (ketones detected) or 'Negative' (no ketones detected). A positive result may indicate diabetic ketoacidosis, fasting or prolonged starvation, a ketogenic diet, alcoholism, or certain metabolic disorders. Your healthcare provider will interpret your results based on your medical history and other test findings.

Reference range

Negative or Not DetectedN/A

Specimen: urine

No fasting required. Collect random urine sample. Inform laboratory of current medications, diet status (ketogenic diet), or if fasting. Avoid contamination of sample with cleansing agents or disinfectants.

Frequently asked questions

Is fasting required before this test?
Fasting is not typically required for a urine acetone test. However, your doctor may ask you to fast for a specific period if they want to evaluate fasting ketone levels. Always follow your healthcare provider's specific instructions.
Can I do this test at home?
Yes, there are home urine ketone test strips available over-the-counter. These can be useful for people with diabetes who need to monitor ketone levels regularly. However, home testing should not replace laboratory testing ordered by your doctor.
What should I do if my result is positive?
If your urine acetone test is positive, contact your healthcare provider immediately, especially if you have diabetes. High ketone levels can be dangerous and may require urgent medical treatment. Your doctor may recommend additional tests and adjust your treatment plan.
Can diet affect my test results?
Yes, certain diets can increase ketone levels. Very low-carbohydrate diets, ketogenic diets, and fasting can cause positive urine ketone results. Inform your doctor about any dietary changes or supplements you are taking.
