How to Test Uric Acid in Your Body

Uric acid, a chemical everyone has in their body, is the byproduct of the breakdown of purines, a substance in DNA and RNA that also occurs in some foods, such as organ meats, anchovies and sardines. Higher than normal levels of uric acid in the body can crystallize around your joints and cause gout, a type of arthritis. Kidney stones also may form from high concentrations of uric acid. If you have either of these conditions, you may be tested to measure the level of uric acid in your body.

Instructions

• 1

  Discuss the medications that you are taking with your doctor before your uric acid levels are tested. You may need to temporarily discontinue your medications to be able to get an accurate reading of your uric acid concentration.

• 2

  Ask your doctor about the tests available to test uric acid levels. The chemical can be measured through a one-time blood draw or from a 24-hour urine test. If your condition requires the use of a urine test, you will be asked to collect all of your urine within a specified 24-hour period in a special container.

• 3

  Fast for four hours prior to your uric acid test if you are having a blood draw. The National Institutes of Health states that food and drink could affect readings of the test. Refrain from all food and water to ensure accurate results.

• 4

  Undergo the test. Your doctor will notify you of the results and any treatments you require.
