Uric Acid in Urine

How It Is Done

A uric acid urine test is usually done on a sample taken from all the urine produced in a 24-hour period.

To collect your urine for 24 hours:

  • You start collecting your urine in the morning. When you first get up, empty your bladder but do not save this urine. Write down the time that you urinated to mark the beginning of your 24-hour collection period.
  • For the next 24 hours, collect all your urine. Your doctor's office or lab will usually provide you with a large container that holds about 1 gal (4 L). The container has a small amount of preservative in it. Urinate into a small, clean container and then pour the urine into the large container. Do not touch the inside of the container with your fingers.
  • Keep the large container in the refrigerator for the 24 hours.
  • Empty your bladder for the final time at or just before the end of the 24-hour period. Add this urine to the large container and record the time.
  • Do not get toilet paper, pubic hair, stool (feces), menstrual blood, or other foreign matter in the urine sample.

Results

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

The normal values listed here—called a reference range—are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab.

Results are usually available in 1 to 2 days.

Uric acid in urine1
Normal:

250–750 milligrams (mg) per 24-hour urine sample

1.48–4.43 millimoles (mmol) per 24-hour urine sample

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.
