Quick answer: A uric acid blood test measures a waste product left over when your body breaks down purines. The normal range is roughly 3.5 to 7.2 mg/dL in men and 2.6 to 6.0 mg/dL in women. High levels can cause gout and kidney stones, though many people with a raised level never develop symptoms at all.

What is uric acid and where does it come from?
Uric acid is the end product of purine breakdown. Purines come from two places: the food you eat, and the normal turnover of your own body cells. Most people are surprised to learn that the larger share is produced internally, not eaten.
Your kidneys clear roughly two thirds of it and the gut handles the rest. Levels rise for one of two reasons: your body is making too much, or your kidneys are not clearing enough. In practice, reduced clearance is the far more common cause, which is why diet alone often fails to fix the problem.
What is a normal uric acid level?
| Group | Typical range | Notes |
|---|---|---|
| Adult men | roughly 3.5 to 7.2 mg/dL | Above 7.0 is generally considered high |
| Adult women | roughly 2.6 to 6.0 mg/dL | Rises after menopause as oestrogen falls |
| Children | roughly 2.0 to 5.5 mg/dL | Varies with age |
Ranges differ between laboratories and analysers. Always read the reference range printed on your own report.
What causes a high uric acid level?
- Reduced kidney clearance, the most common mechanism. Any decline in kidney function raises uric acid
- Diuretics and some blood pressure medicines, which are a frequently missed cause
- Low dose aspirin, taken long term by many cardiac patients
- Obesity and metabolic syndrome
- Alcohol, particularly beer
- Sugary drinks and anything with high fructose corn syrup, a stronger driver than most people realise
- Red meat and organ meats such as liver, kidney and brain
- Certain seafood, including prawns and sardines
- Rapid weight loss or prolonged fasting, which temporarily raises levels
- Some blood disorders and cancer treatments, where cell turnover is very high
What is gout and how does it relate?
When uric acid concentration exceeds what the blood can hold, it forms sharp crystals that settle in joints. The immune system attacks those crystals and the result is gout: sudden, intense joint pain, usually starting at night.
The classic presentation is the base of the big toe, which becomes red, hot, swollen and so tender that even the weight of a bedsheet hurts. Ankles, knees, wrists and fingers can also be affected.
An important detail that confuses many patients: a normal uric acid level during an acute attack does not rule out gout. Levels frequently drop during the attack itself, because the uric acid has moved out of the blood and into the joint. Testing again two to four weeks after the attack settles gives a truer picture.
Does high uric acid always need treatment?
No, and this is worth understanding clearly.
Many people have a raised uric acid level and never develop gout or stones. This is called asymptomatic hyperuricaemia, and it usually does not require uric acid lowering medication on its own.
Treatment is generally considered when there have been gout attacks, when uric acid kidney stones have formed, when there are visible deposits under the skin called tophi, or where a very high level is expected during cancer treatment. Your doctor makes that call, weighing your overall picture rather than a single number.
Uric acid and kidney stones
Uric acid can also crystallise in the kidney, forming stones. These stones have a particular characteristic worth knowing: they often do not show on a plain X-ray, because they are radiolucent. This is why ultrasound or CT is used when a uric acid stone is suspected and the X-ray looks clear.
Staying well hydrated is the single most effective preventive step, which matters especially through Lahore summers when dehydration is common.
How to prepare for the test
- Fasting for 8 to 12 hours is usually advised, since a purine rich meal can raise the reading
- Avoid alcohol for 24 hours beforehand
- Tell the laboratory about diuretics, aspirin and any gout medication you take
- Do not test in the middle of an acute attack if the purpose is to establish your baseline. Wait two to four weeks
- Drink water normally, as dehydration raises the result
Who should be tested?
- Sudden severe pain, swelling and redness in a single joint, especially the big toe
- Recurring joint pain of unclear cause
- A history of kidney stones
- Anyone on long term diuretics
- People with reduced kidney function
- Patients starting chemotherapy, where cell breakdown releases large amounts of uric acid
- As part of a general health check alongside blood sugar and lipid testing
Uric acid testing at Al-Nasar Lab
Al-Nasar Lab & Diagnostic Centre has provided laboratory testing in Lahore since 1996 and holds ISO 15189:2022 accreditation from the Pakistan National Accreditation Council. Uric acid is available on its own or as part of a kidney function panel, with home sample collection across Lahore and same day digital reports. Where stones are suspected, ultrasound and CT are available at our Johar Town campus.

Frequently Asked Questions
What is a normal uric acid level?
Roughly 3.5 to 7.2 mg/dL in men and 2.6 to 6.0 mg/dL in women. Ranges differ between laboratories, so read the range on your own report.
Do I need to fast for a uric acid test?
Fasting for 8 to 12 hours is usually advised, because a purine rich meal shortly before the test can raise the result.
Can I have gout with a normal uric acid level?
Yes. Levels often fall during an acute attack because the uric acid has deposited in the joint. Retesting two to four weeks later gives a more accurate baseline.
Which foods raise uric acid most?
Organ meats, red meat, some seafood, beer and sugary drinks containing fructose. That said, most uric acid is produced by the body rather than eaten, so diet alone rarely normalises a high level.
Does high uric acid always mean I need medicine?
No. Many people have raised levels without symptoms and need no uric acid lowering treatment. Medication is usually considered after gout attacks, stones or visible deposits. Your doctor decides.
