Uric Acid 24-Hour Urine Test – Accurate Diagnosis for Gout, Kidney Stones & Metabolic Health

The Uric Acid 24-Hour Urine Test from Lab Tests Dubai is a critical diagnostic tool for identifying the root cause of recurrent gout, kidney stones, and hyperuricemia. Unlike a single blood test, this 24-hour urine collection measures total uric acid excretion over a full day, helping doctors determine whether your body is overproducing uric acid or under-excreting it through the kidneys—a key distinction for effective treatment.

Using advanced spectrophotometry, this test delivers highly accurate results within just 1 day, making it essential for:

• Diagnosing gout and hyperuricemia
• Evaluating kidney stone risk (especially uric acid stones)
• Guiding treatment with allopurinol (for overproducers) or probenecid (for underexcretors)
• Monitoring patients on chemotherapy or metabolic disorder therapies

Available with home collection kits and detailed instructions, Lab Tests Dubai makes comprehensive urine testing simple, accurate, and stress-free.

Why You Need This Test

If you suffer from gout attacks or kidney stones, knowing why your uric acid is high is the key to effective treatment.

You need this test if:

• You’ve had two or more gout flare-ups
• You pass uric acid kidney stones
• Your blood uric acid is high, but you’re not sure why
• You’re being considered for long-term uric acid-lowering medication
• You have chronic kidney disease or are on diuretics
• You’re undergoing cancer treatment (risk of tumor lysis syndrome)

This test answers a crucial question:

❓ “Is my body making too much uric acid—or not flushing it out?”

This guides whether you need:

• Allopurinol/febuxostat (reduce production)
• Probenecid/lesinurad (increase excretion)
• Or just lifestyle changes

Without this test, treatment may be ineffective or even harmful.

Symptoms That Indicate This Test

Consider the Uric Acid 24-Hour Urine Test if you experience:

✅ For Gout:

• Sudden, severe joint pain (often in the big toe)
• Redness, swelling, and warmth in joints
• Recurrent gout attacks despite medication

✅ For Kidney Stones:

• Severe flank or lower back pain
• Blood in urine (hematuria)
• Pain during urination
• History of uric acid stones on imaging

✅ Other Indicators:

• Family history of gout or kidney stones
• High-purine diet (red meat, shellfish, alcohol)
• Obesity, metabolic syndrome, or insulin resistance

Even if you feel fine, silent hyperuricemia can damage joints and kidneys over time.

Natural Production: How Uric Acid Forms & Is Eliminated

Uric acid is a natural byproduct of purine metabolism—purines come from:

• Body cell turnover (endogenous – 80%)
• Diet (exogenous – 20%): red meat, organ meats, shellfish, beer, fructose

It’s processed as follows:

1. Purines → Xanthine → Uric Acid (in liver)
2. Uric acid enters blood → filtered by kidneys
3. ~70% excreted in urine, 30% in feces

Problems arise when:

• Overproduction: Fast cell turnover (cancer, psoriasis), high-purine diet
• Underexcretion: Kidney disease, diuretics, insulin resistance, dehydration

This test measures 24-hour uric acid excretion:

• <600 mg/day → Normal or underexcretion
• >800 mg/day → Overproduction
• Helps guide precision treatment

What Happens If Untreated? Risks of High Uric Acid

Ignoring abnormal uric acid levels can lead to serious complications:

⚠️ Chronic Gout & Joint Damage

• Uric acid crystals destroy cartilage → joint deformity, disability

⚠️ Kidney Stones & Nephropathy

• Uric acid stones → blockage, infection, kidney damage
• Crystal deposits in kidneys → chronic kidney disease

⚠️ Cardiovascular & Metabolic Risks

• Linked to hypertension, heart disease, insulin resistance

⚠️ Tumor Lysis Syndrome (in cancer patients)

• Rapid cell death → massive uric acid surge → acute kidney failure

Early testing allows for targeted therapy, diet changes, and prevention of irreversible damage.

How to Prepare for the Test

To ensure accurate results:

✅ Start fresh in the morning: Empty your bladder and discard the first urine
✅ Collect ALL urine over the next 24 hours in the provided container
✅ Keep the container refrigerated throughout collection
✅ Avoid high-purine foods 24 hours before and during:

• Red meat, organ meats, shellfish
• Alcohol (especially beer)
• Sugary drinks (high-fructose corn syrup)
  ✅ Stay normally hydrated—don’t overdrink or dehydrate
  ✅ Inform your doctor of:
• Diuretics, aspirin, vitamin C, or gout medications
• Recent illness or chemotherapy

Our team provides a complete 24-hour urine kit with step-by-step instructions and home collection support.

Test Overview: Precise Spectrophotometry Method

Spectrophotometry measures uric acid by detecting UV light absorption—ensuring high accuracy and reproducibility.

Interpretation:

• <600 mg/24h → Low excretion (underexcretor)
• 600–800 mg/24h → Normal
• >800 mg/24h → Overproducer (common in gout)

Results are reported with clinical notes for your doctor.

FAQs About the Uric Acid 24-Hour Urine Test

Q: Can I eat normally during the test?
A: No. Avoid high-purine foods and alcohol to reflect baseline excretion.

Q: What if I miss a urine sample?
A: The test will be invalid. You’ll need to restart the collection.

Q: Can medications affect the result?
A: Yes. Diuretics, aspirin, pyrazinamide, and vitamin C can alter excretion.

Q: Can I book without a doctor’s referral?
A: Yes! Lab Tests Dubai allows direct online booking—ideal for gout or stone sufferers.

Q: How will I get results?
A: A secure digital report is emailed within 24 hours of sample receipt, including total uric acid and reference range.

Q: Is this test better than a blood uric acid test?
A: It’s complementary. Blood shows current level; 24-hour urine shows how your body handles it.

If you’re tired of gout flare-ups or kidney stones, the Uric Acid 24-Hour Urine Test gives you the answers you need to treat the cause—not just the symptoms.
