What is this test?
Uric acid is produced from purine breakdown and removed mainly through the kidneys. High levels increase the likelihood of gout and some kidney stones but do not prove either condition.
Why might it be ordered?
- To investigate or monitor gout and uric-acid stones.
- To monitor medicines or conditions that can raise uric acid.
What sample is needed?
A blood sample is required. The laboratory chooses the correct tube and handles the sample for this test.
How should you prepare?
Ask the laboratory whether you need to fast or attend at a particular time. Do not stop or change medicines or supplements unless your clinician tells you to.
How should you understand the result?
A person can have a high level without symptoms, and the value can fall during an acute gout flare. Treatment targets are individualized for people receiving urate-lowering therapy.
