Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like joint pain, kidney problems, or if they suspect conditions like gout, kidney stones, or certain types of arthritis. It may also be used to monitor treatments for these conditions or check for metabolic disorders.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for 8–12 hours before the test if it involves a blood draw. Hydration can sometimes affect uric acid levels, so drink as much water as you normally would unless instructed otherwise.

How the Test Is Performed

A healthcare professional will draw blood from a vein in your arm using a small needle. The blood sample is then sent to a lab for analysis. The test measures the concentration of uric acid in your serum or plasma.

Possible Results and Their Meaning

Higher-than-normal levels may suggest conditions like gout, kidney disease, or certain cancers. Lower-than-normal levels might indicate overuse of certain medications (like aspirin or diuretics) or genetic factors. Your results will be interpreted by your provider in the context of your overall health.

Frequently asked questions

What does a high uric acid level mean?
High uric acid levels often point to gout, kidney issues, or metabolic syndrome. It can also be linked to conditions like hypertension or obesity. Repeatedly high levels may increase the risk of kidney stones or heart disease, so monitoring is important.
What does a low uric acid level mean?
Low uric acid levels are less common but may occur with certain medications, liver disease, or genetic disorders. Your provider will discuss this with you if your results fall outside the expected range.
Can diet affect uric acid levels?
Yes, diet plays a role. Foods high in purines (like red meat, organ meats, and some seafood) can raise levels. Alcohol, especially beer, may also contribute. Staying hydrated and maintaining a balanced diet can help manage uric acid levels.
