Metabolic
Uric Acid
LOINC 3084-1 · mg/dL
What it is
Uric acid is a waste product formed when the body breaks down purines, substances found in some foods and in your own cells.
Why it matters
High levels can form crystals that cause gout, and the test also helps monitor kidney handling of uric acid.
What high values can mean
A higher value can lead to gout attacks and kidney stones and may relate to diet, alcohol or reduced kidney clearance.
What low values can mean
A lower value is usually not a concern.
How to improve it
Staying hydrated, moderating alcohol and high-purine foods, and managing weight help lower uric acid.
Food & lifestyle
Limit organ meats, shellfish, red meat, beer and sugary drinks; water, coffee and dairy may help.
Preparing for the test
A blood test; fasting may be requested — follow your lab's instructions.
When to talk to a doctor
Discuss a high uric acid with a doctor, especially with painful, swollen joints.
