Why This Test Matters

Uric acid is a waste product that your kidneys normally filter out of your blood and release in your urine. High levels may suggest problems like kidney disease, gout, or conditions that affect how your body processes uric acid.

What to Expect Before the Test

You’ll collect all urine produced in a 24-hour period in a special container. Drink plenty of fluids to help ensure accurate results, but avoid foods high in purines (like organ meats or shellfish) for 24 hours before testing.

What Happens During the Test

No special preparation is needed beyond the 24-hour urine collection. Your sample will be sent to a lab for analysis to measure uric acid levels.

Possible Results and Interpretation

High uric acid levels may indicate kidney issues, gout, or metabolic disorders. Low levels are less common but could suggest certain genetic conditions or malabsorption problems.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance: Uric Acid Levels

Frequently asked questions

What causes elevated uric acid levels?
Elevated uric acid can result from diet, genetics, kidney problems, or conditions like diabetes or obesity. It’s often linked to gout attacks or kidney stones but isn’t always harmful unless severe.
Can diet affect this test?
Yes—high-purine foods (red meat, seafood) and alcohol can raise uric acid. Avoiding these for 24 hours before testing helps get a clearer picture of your baseline levels.
What if my results are abnormal?
If uric acid is high, your doctor may recommend lifestyle changes (like hydration, weight management) or further tests to check for kidney function or gout. Follow-up depends on your symptoms and test results.
