What is this test?

The urine acetone test measures the amount of acetone, a type of ketone body, in your urine. Ketones are produced when your body breaks down fat for energy instead of using glucose. This test is commonly used to monitor people with diabetes and check for a potentially serious condition called diabetic ketoacidosis (DKA).

Why is it ordered?

Your doctor may order this test if you have diabetes and experience symptoms like frequent urination, excessive thirst, or nausea. It is also used to monitor metabolic conditions, evaluate unexplained weight loss, or check for complications during pregnancy (gestational diabetes). The test helps determine if your body is properly using insulin or if dangerous ketone buildup is occurring.

How is the test done?

A urine sample is collected in a sterile container. You may be asked to clean your genital area before collection to avoid contamination. For a clean-catch sample, you will begin urinating into the toilet, then stop, then collect the mid-stream urine into the container. The sample is sent to a laboratory for analysis. No fasting or special preparation is typically required, but follow your doctor's specific instructions.

Understanding your results

Results are typically reported as negative, small, moderate, or large amounts of acetone. A negative or trace result is generally normal. Moderate to large amounts of acetone in urine may indicate diabetic ketoacidosis, starvation, a very low-carbohydrate diet (like the keto diet), or other metabolic disorders. Your doctor will interpret results based on your overall health, symptoms, and other test findings.

Frequently asked questions

Do I need to fast before the test?
Generally, no fasting is required for a urine acetone test. However, tell your doctor about any medications, supplements, or special diets (like keto or Atkins) you are following, as these can affect results.
What do high acetone levels mean?
High acetone levels in urine may indicate diabetic ketoacidosis (DKA), which requires immediate medical attention. Other causes include prolonged fasting, very low-carbohydrate diets, excessive alcohol consumption, or certain metabolic disorders. Your doctor will determine the cause and appropriate treatment.
Is the test painful?
No, the urine acetone test is completely painless. It only requires providing a urine sample, similar to a routine urinalysis.
How often should I have this test?
Frequency depends on your health condition. People with diabetes may test ketone levels at home using dipsticks during illness or when blood sugar is consistently high. Your doctor will recommend how often you need laboratory testing based on your individual situation.
