Urine Ketones (Qualitative, 24-Hour Collection)

This test is done to give your doctor important information about your health. It can help find a health problem early, show how well part of your body is working, or check how well a treatment is going. Knowing these details helps your care team choose the safest and most effective plan for you.

Your healthcare provider may order this test to monitor conditions like diabetes, starvation, or metabolic disorders where fat breakdown (ketosis) occurs. It helps assess whether your body is efficiently using energy sources or if additional support is needed.

Before the test, your care team will give you clear instructions on how to prepare. You may be asked to avoid eating or drinking for a certain amount of time, or to pause some medicines. Wear comfortable, loose clothing, bring a list of your current medications, and arrive a little early so you have time to check in and ask any questions.

You’ll collect all urine produced in a 24-hour period in a sterile container. Drink plenty of fluids to ensure adequate urine output. Avoid certain medications or supplements that might interfere with results.

During the test, a trained member of your care team will walk you through each step and answer your questions along the way. The test is designed to be safe, and most people tolerate it well. It usually takes only a short time, and you can normally go home the same day unless your doctor tells you otherwise.

The collected urine sample is tested for the presence of ketones using a chemical reaction that detects their concentration. Results are reported as either positive (ketones present) or negative (no ketones detected).

Your results will help your doctor better understand your health. Results within the normal range may mean everything looks as expected, while results outside that range can point to a condition that needs a closer look. Your doctor will contact you to explain what your results mean and discuss any next steps in your care.

Positive results suggest elevated ketone levels, which may indicate conditions like diabetic ketoacidosis, starvation, or prolonged fasting. Negative results mean no significant ketones were detected in your urine.
