The Uric Acid test measures the level of uric acid — a waste product formed when the body breaks down purines (found in certain foods and body cells) — in the blood. Persistently elevated uric acid (hyperuricaemia) causes urate crystals to deposit in joints (causing gout) and kidneys (causing uric acid kidney stones). This test is used to diagnose gout, monitor urate-lowering treatment, screen for kidney stone risk, and assess kidney disease.
Key benefits of this package include:
What Does the Uric Acid Test Measure?
| Level / Result | Possible Interpretation |
|---|---|
| Normal (Males 3.4–7.0 | Females 2.4–6.0 mg/dL) | Normal purine metabolism and kidney urate excretion |
| Mildly elevated (7.0–9.0 mg/dL) | Hyperuricaemia — increased gout and kidney stone risk; dietary modification advised |
| Moderately elevated (9.0–12.0 mg/dL) | Significant hyperuricaemia — gout likely or imminent; medical management required |
| > 12.0 mg/dL (Severely elevated) | Severe hyperuricaemia — risk of acute gout attack, urate nephropathy, tumour lysis |
| Below normal (< 2.0 mg/dL) | Hypouricaemia — rare; may occur with certain genetic conditions, SIADH, or xanthine oxidase deficiency |
Important Note: Uric acid levels fluctuate throughout the day and can be affected by diet, alcohol, medications, and hydration. A single elevated reading does not always indicate gout — clinical symptoms, joint examination, and sometimes synovial fluid analysis are needed to confirm the diagnosis. Results should always be reviewed by a physician.
Gout vs. Pseudo-gout: While gout is caused by monosodium urate crystal deposition (elevated uric acid), pseudo-gout is caused by calcium pyrophosphate crystal deposition — and serum uric acid levels are normal in pseudo-gout. If a patient has acute joint inflammation with normal uric acid, pseudo-gout or other arthritis diagnoses should be considered. Serum uric acid alone cannot diagnose gout — the gold standard remains synovial fluid microscopy showing negatively birefringent crystals.
