About Uric Acid

This test measures the amount of uric acid in a sample of your blood or urine (pee). Uric acid is a normal waste product that your body makes when it breaks down chemicals called purines. Purines come from your cells when they die. Purines are also found in many foods and beverages.

Most uric acid dissolves in your blood. Your kidneys filter the uric acid out of your blood, and it leaves your body in your urine. If uric acid builds up in your blood, it can form needle-shaped crystals in and around your joints. This condition is called gout.

Gout is a type of arthritis that causes painful swelling in your joints. High uric acid levels can also cause kidney stones, or kidney failure. But not everyone with high levels of uric acid will have these problems.

Useful for

Help diagnose gout, usually when done with a synovial fluid analysis

Monitor uric acid levels in people who are having cancer chemotherapy or certain other cancer treatments, since treatment can release large amounts of purines into the blood and lead to high uric acid levels

Help find out whether high levels of uric acid are causing kidney stones

Monitor the risk of developing kidney stones in people who have gout

Help evaluate certain kidney and metabolic conditions, including kidney problems and other disorders such as leukemia or psoriasis

Main source: MedlinePlus ↗

Interpretation

High uric acid levels in a blood test may be a sign of a problem that needs further evaluation. As a general guide, uric acid is considered high above about 8.0 mg/dL in men and above 6.1 mg/dL in women, but only some people with high uric acid develop gout or other problems.

Your provider may order more tests to help diagnose what's causing the issue, since high levels of uric acid can be related to many conditions such as kidney problems, gout, certain blood cancers like leukemia, psoriasis, or periods of starvation or rapid tissue breakdown. Levels can also rise in people receiving certain cancer-fighting medicines.

Low levels of uric acid in blood are uncommon and usually don't cause health problems. They can occasionally be seen with severe liver disease, certain inherited conditions, or with some treatments such as allopurinol or specific cancer drugs. Health conditions that are related to low uric acid levels are usually diagnosed using other tests.

High uric acid levels can also be measured in urine and may point to related conditions. Talk with your provider to understand what your specific results mean.
