Uric Acid: What It Means for Your Health
Uric acid is produced when the body breaks down purines — natural substances found in many foods (red meat, organ meats, seafood) and in your body's own cells. Normally, uric acid dissolves in the blood, passes through the kidneys, and is excreted in urine. When production is excessive or excretion is inadequate, uric acid crystals can deposit in joints (gout) and kidneys (stones).
Reference Range
Reference ranges may vary between laboratories, age groups, and sexes. The values shown are general adult reference ranges. Always compare your results to the specific range provided by your testing laboratory.

What Does High Uric Acid Mean?
Elevated uric acid (hyperuricemia) can cause gout (painful joint inflammation, classically in the big toe), kidney stones, and kidney damage. It is associated with metabolic syndrome, obesity, alcohol use, high-purine diets, kidney disease, and certain medications (diuretics). Emerging research links chronic hyperuricemia to cardiovascular disease and hypertension.
What Does Low Uric Acid Mean?
Low uric acid is uncommon and may indicate kidney disease (excessive excretion), liver disease (reduced production), Wilson's disease, Fanconi syndrome, or a very low-purine diet. Certain medications (allopurinol for gout) intentionally lower uric acid.
