Serum/plasma mass concentration of uric acid (via immunoassay)

What Does This Test Measure?

Uric acid is a waste product created when your body processes certain nutrients, such as those found in high-purine foods. Normally, your kidneys filter it out through urine. However, if uric acid builds up in your bloodstream, it can lead to conditions like gout or kidney stones. This test helps doctors assess your uric acid levels to check for these or other potential health issues.

Why Might You Need This Test?

Your healthcare provider may order this test if you have symptoms like joint pain, kidney problems, or if you’re at risk for conditions like gout or kidney stones. It can also be part of routine check-ups for certain groups, such as people with high blood pressure or diabetes.

How Is the Test Done?

A small blood sample is taken from a vein in your arm. The blood is then sent to a lab where it is analyzed to measure the uric acid concentration. The test typically takes a few minutes, and you may feel slight discomfort but no lasting effects.

What Are the Possible Results?

Results are reported as a mass concentration (typically in mg/dL or mmol/L). While specific reference ranges vary by lab, high levels may signal potential health concerns that need further evaluation, such as kidney function issues or metabolic disorders.
