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 or kidney stones. It can also be part of routine check-ups for those at higher risk.

What to Expect Before the Test

No special preparation is needed for this test. You may have a small needle inserted into your arm to draw blood. If you’re on a low-purine diet (commonly advised for gout), avoid eating high-purine foods like organ meats, shellfish, or red meat for 24 hours before testing.

What to Expect During the Test

The blood sample is taken from a vein in your arm. You may feel a slight pinch, but it usually doesn’t cause significant discomfort. The test itself is quick and painless.

What the Results Mean

High uric acid levels may indicate conditions like gout, kidney disease, or metabolic disorders. Low levels are less commonly significant unless related to certain medications or genetic factors.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

High uric acid levels can lead to kidney stones, gouty arthritis, and other health issues. Regular monitoring helps manage these risks, especially for people with a family history of gout or kidney problems.
