A uric acid test measures the level of uric acid in your blood. Uric acid is a waste product formed when the body breaks down purines, found in your cells and in foods such as red meat, organ meat, some seafood and alcohol. Normal levels are about 3.4–7.0 mg/dL in men and 2.4–6.0 mg/dL in women.
What does the uric acid test measure?
Most uric acid dissolves in the blood, passes through the kidneys and leaves in urine. When the body makes too much, or the kidneys clear too little, levels build up. This is called hyperuricaemia. High uric acid matters for two main reasons:
- Gout: Excess uric acid can form needle-like crystals in a joint, causing sudden, severe pain, redness and swelling, classically at the base of the big toe, often starting at night.
- Kidney stones: Uric acid crystals can also form stones in the kidneys.
Many people with high uric acid never get gout or stones, and doctors do not usually treat a high number on its own without symptoms. But it is a useful marker: raised uric acid often travels with abdominal weight gain, high blood pressure, high triglycerides and insulin resistance, a cluster common among Indian urban professionals. Common contributors include:
- Diet: Red and organ meats, some seafood, beer and spirits, and drinks sweetened with fructose (sodas, packaged juices).
- Excess body weight and crash dieting or prolonged fasting.
- Medicines: Some diuretics (water pills) and low-dose aspirin.
- Dehydration and reduced kidney function.
- Genetics: Gout often runs in families.
Uric acid normal range
Where does your result fall?
Enter your Uric acid value from your report.
A general guide, not a diagnosis. The reference range on your own report takes priority, and a doctor should interpret any result outside it.
To convert, mg/dL × 59.48 = µmol/L. Ranges vary between labs and methods. Always compare your result with the reference range printed on your own report.
What abnormal results can mean
- High uric acid with joint pain: Can suggest gout. Uric acid can read normal during an acute attack, so a normal result does not rule gout out.
- High uric acid without symptoms: Often linked to diet, weight, alcohol or medicines. Your doctor may suggest lifestyle changes and recheck.
- Low uric acid: Uncommon and usually not significant; occasionally linked to certain medicines or rare kidney or liver conditions.
Who should get this test?
- Anyone with sudden, painful, swollen joints, especially the big toe, ankle or knee.
- People with kidney stones or a family history of gout.
- People with metabolic risk factors: excess weight, high blood pressure, diabetes or high triglycerides.
- People on medicines that can raise uric acid, and those being treated for gout.
- Preparation: Some labs advise 4–8 hours of fasting. Avoid alcohol and heavy meat or seafood meals for 24 hours, and strenuous exercise the day before.
