What it measures
The level of uric acid in blood.
Why it is ordered
Relevant to acute joint attacks and to kidney stones. Note: during an acute attack the value may not reflect the usual level, so timing matters.
How to prepare
Usually fasting. Ask whether alcohol and certain foods should be avoided for a few days beforehand.
