The blood uric acid test measures the
amount of uric acid in a blood sample.
The normal values listed here—called a reference range—are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab.
Results are usually ready in 1 to 2 days.
Uric acid crystals sometimes form in
joints even at levels less than 7 mg/dL, especially in men. This can lead to a
gout attack, even though the uric acid levels are
within the normal range.
Many conditions can change uric acid
levels. Your doctor will talk with you about any abnormal results that may be
related to your symptoms and past health.
