What is this test?

The acetazolamide 24-hour urine test measures the amount of acetazolamide that your body passes through urine over a 24-hour period. Acetazolamide is a prescription medication called a carbonic anhydrase inhibitor, commonly used to treat glaucoma, altitude sickness, certain types of epilepsy, and fluid retention (edema).

Why is this test performed?

Your doctor may order this test to: monitor whether you are taking your medication as prescribed, check if the drug is at the right level in your body, evaluate how well the medication is working, or adjust your dosage if needed. This is particularly important for medications where therapeutic levels need to be carefully maintained.

How to prepare for the test

Follow these steps for a successful 24-hour urine collection: 1) Ask your doctor if you should stop taking acetazolamide before the test, 2) Start the collection at a specific time (usually morning) as instructed, 3) Collect all urine throughout the day and night, 4) Keep the collection container refrigerated or in a cool place, 5) Return the container to the lab as instructed, preferably within the same day the collection ends.

What happens during the test?

You will be given a special collection container. For 24 hours, every time you urinate, you must collect the urine in the container. This includes the first morning urine on day one (which you may skip), and the first morning urine on day two (which you should include). Write down the start and end times of your collection. Keep the container sealed and refrigerated during the collection period.

Understanding your results

Your test results will show the total amount of acetazolamide excreted in your urine over 24 hours. Your doctor will interpret these results based on your specific condition, dosage, and overall health. Therapeutic levels vary depending on what condition is being treated. Your healthcare provider will discuss what your specific results mean for your treatment plan.
