    Uric Acid in Urine

    The uric acid urine test measures the amount of uric acid in a sample of urine collected over 24 hours.

    Uric acid is made from the natural breakdown of your body's cells. It's also made from the foods you eat. Your kidneys take uric acid out of your blood and put it into urine so that it can leave your body.

    But if your body is making too much uric acid, the level in the urine can get too high. And if your kidneys aren't working the way they should, the level of uric acid in the urine can get too low.

    High levels of uric acid can cause crystals to form in joints. This causes a painful problem called gout. If gout isn't treated, the crystals can build up and form hard lumpy deposits called tophi.

    High uric acid levels can also cause kidney stones.

    Why It Is Done

    This test is done to:

    • See if kidney stones were caused by high uric acid levels.
    • Find the cause of a high level of uric acid in the blood and help choose the proper treatment.

    How To Prepare

    No special preparation is needed. You don't need to limit liquids or foods before the test. Make sure you drink enough liquids during the 24-hour test so that you don't get dehydrated.

    During the 24-hour period, don't drink alcohol. It lowers the amount of uric acid eliminated by the kidneys.

    Many medicines can change the results of this test. Be sure to tell your doctor about all the over-the-counter and prescription medicines you take.

    Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results may mean. To help you understand the importance of this test, fill out the medical test information form(What is a PDF document?).
