About Uric Acid
Uric acid builds up when your body breaks down purines, substances found naturally in your body and in foods like red meat, organ meat and certain seafood. When levels run high, uric acid crystals can settle in joints and cause gout, or contribute to kidney stones.
We recommend an 8 hour fast where possible, though it is not strictly mandatory, since food closer to the test can nudge results slightly higher. If you have joint pain, especially in the big toe, this is often one of the first tests your doctor will order.
Results come back the same day, giving your doctor a quick answer on whether diet changes or medication are needed.
How to Prepare
- An 8-hour fast is preferred for the most accurate reading, though not mandatory.
- Avoid heavy red meat or alcohol the evening before if possible.
Frequently Asked Questions
What causes high uric acid levels?
High uric acid usually comes from eating purine-rich foods like red meat and organ meat, reduced kidney clearance, or certain medical conditions, and it is commonly linked to gout.
Do I need to fast before a uric acid test?
A short fast of around 8 hours is preferred but not mandatory. We can still run the test if you have eaten recently.
What symptoms suggest I should get my uric acid checked?
Sudden joint pain and swelling, especially in the big toe, along with a family history of gout, are common reasons to test uric acid levels.
Can diet lower my uric acid level?
Yes, reducing red meat, organ meat, alcohol and sugary drinks can meaningfully lower uric acid over time, alongside any medication your doctor prescribes.
How soon will my uric acid report be ready?
Same day, usually within a few hours of your blood draw.
Is home sample collection available for uric acid testing?
Yes, in all City Care Lab service areas, which is helpful for patients dealing with painful joint flare-ups who would rather not travel.
