Home > Health Library > Uric Acid in Urine Test
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.
This test is done to:
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.
A uric acid urine test is usually done at home. You must collect all the urine you produce in a 24-hour period.
This test usually doesn't cause any pain or discomfort.
There are no known risks from having this test.
Results are usually available in 1 to 2 days.
Each lab has a different range for what's normal. Your lab report should show the range that your lab uses for each test. The normal range is just a guide. Your doctor will also look at your results based on your age, health, and other factors. A value that isn't in the normal range may still be normal for you.
Women typically have slightly lower uric acid levels than men.
Many conditions can change uric acid levels. Your doctor will talk with you about any abnormal results that may be related to your symptoms and past health.
