Serum Uric Acid Test
The serum uric acid test measures the amount of uric acid (urate) in your blood and is most often ordered when a doctor suspects gout, kidney stones, or kidney problems. In Bangladesh, this simple blood test is available at nearly all private labs. It usually requires 8–10 hours of fasting beforehand and costs roughly 300–800 BDT. However, the result only makes sense when a clinician reads it alongside your symptoms and medical history — a number alone is not a diagnosis.
What does the serum uric acid test measure?
The test measures serum urate — the final breakdown product of purines. Purines come from two sources: your body’s own cells (internal turnover) and certain foods you eat (red meat, organ meat, dried fish, shellfish, and some legumes). When purines break down, uric acid is formed. Normally, your kidneys filter most of it out through urine. If the body produces too much uric acid or the kidneys cannot excrete it efficiently, levels in the blood rise — a condition called hyperuricemia.
Why would a doctor order this test?
There are several common reasons:
- Suspected gout: Sudden, severe joint pain (often the big toe), redness, and swelling. Gout can occur when uric acid crystallises in a joint.
- Kidney stones: Uric acid stones are one type of kidney stone. The test helps identify the cause.
- Chronic kidney disease (CKD): Impaired kidneys cannot clear uric acid well, so rising levels can signal worsening function.
- Chemotherapy monitoring: Some cancer treatments cause rapid cell death (tumour lysis syndrome), releasing large amounts of uric acid that can damage the kidneys.
- Recurrent urinary tract stones or unexplained flank pain also warrant checking uric acid levels.
How should you prepare for the test?
Preparation is generally straightforward, but following these steps helps ensure accurate results:
- Fasting: Many labs ask you to fast for 8–10 hours before the blood draw. You may drink plain water during this time.
- Avoid alcohol and purine-rich foods the night before and on the day of the test. This includes red meat, liver, kidney, dried fish (shutki), shellfish, and excessive pulses.
- Tell your doctor and the lab about all medications you take, especially diuretics (water pills), low-dose aspirin, allopurinol, febuxostat, or any chemotherapy drugs. These can significantly alter your uric acid level.
- No other special restrictions are typically needed. You can continue other regular medicines unless instructed otherwise.
What do the results mean? (Normal ranges)
Reference ranges vary from one laboratory to another. Always compare your result against the range printed on your own report. Below are typical adult ranges used by many Bangladeshi labs:
| Group | mg/dL | µmol/L | Notes |
|---|---|---|---|
| Men (adult) | 3.5 – 7.2 | 210 – 430 | Some labs use slightly higher upper limits (e.g., 8.0 mg/dL) |
| Women (adult) | 2.6 – 6.0 | 155 – 357 | Levels may rise after menopause |
| Children | 2.0 – 5.5 | 120 – 330 | Consult a paediatrician for interpretation |
If your result falls outside these typical ranges, do not panic. Many factors — recent diet, medications, hydration, kidney function — can affect a single reading. The doctor will interpret it in context.
High vs low uric acid: what it does and doesn’t mean
High uric acid (hyperuricemia) does not always cause gout or kidney stones. Many people with elevated uric acid never develop symptoms. Gout is confirmed when a person has sudden, severe joint pain and uric acid crystals are found in joint fluid. Other causes of high uric acid include kidney disease, obesity, hypothyroidism, certain medications, and a high-purine diet.
Low uric acid (hypouricemia) is less common and may be due to liver disease, certain kidney disorders that waste uric acid, or medications such as allopurinol. It rarely causes symptoms on its own but should still be investigated.
| Result pattern | What it may suggest | Next step |
|---|---|---|
| High uric acid + sudden joint pain + swelling (especially big toe) | Probable gout (but needs joint fluid analysis for confirmation) | See a rheumatologist or nephrologist. Do not self-treat. |
| High uric acid + flank pain, blood in urine, or stone history | Possible uric acid kidney stones | See a urologist for imaging (CT, ultrasound) and stone analysis. |
| High uric acid alone, no symptoms | Asymptomatic hyperuricemia | Do not start medication automatically. Address diet and underlying causes. Monitor with regular check-ups. |
| Low uric acid | May be due to liver disease, over-correction by drugs, or renal urate wasting | Consult a nephrologist to identify the underlying cause. |
How much does the test cost in Bangladesh?
The cost of a serum uric acid test varies by city, lab quality, and whether you choose a single test or a package. Below are approximate ranges in private labs and hospitals across Bangladesh as of early 2025. Prices change, so always confirm when you book.
| Item | Approx. BDT range | Notes |
|---|---|---|
| Serum uric acid (alone) | 300 – 800 | Most common range in Dhaka and divisional cities |
| Uric acid + creatine (kidney function check) | 400 – 900 | Often ordered together to assess filtration |
| Kidney function panel (uric acid, creatine, BUN, electrolytes) | 500 – 1,200 | Includes several tests at a bundle price |
| Comprehensive metabolic panel (includes uric acid, liver enzymes, etc.) | 800 – 1,500 | Useful for monitoring during chemotherapy |
Reminder: Prices are approximate. Check with 2–3 labs near you before deciding. Many labs also offer home collection for an extra fee (typically 50–100 BDT).
When should you see a doctor?
You should consult a doctor if you experience any of the following:
- Sudden, severe joint pain – especially in the big toe, ankle, or knee, often at night, with redness and warmth. This could be gout.
- Flank pain or discomfort – may indicate kidney stones.
- Blood in urine (hematuria) or frequent painful urination.
- Known kidney disease and a recent rise in uric acid levels without a clear cause.
- Unexpectedly high or low uric acid on routine testing, especially if you take diuretics or other medications that affect it.
For abnormal results or symptoms, consult a nephrologist (kidney specialist) or a rheumatologist (arthritis and gout specialist). In many cases, a urologist is also relevant for stones. Use the table below to find specialists in your division.

Frequently Asked Questions
What is the difference between a serum uric acid test and a urine uric acid test?
A serum uric acid test measures the uric acid level in your blood. A urine uric acid test measures how much uric acid your kidneys are excreting over 24 hours. Doctors sometimes order both to determine whether the problem is excess production or reduced removal by the kidneys. The two tests require different sample collection, so follow the exact instructions your doctor gives you.
Can I take my regular medicines before a serum uric acid test?
In most cases, you should continue your prescribed medicines unless your doctor tells you otherwise. However, some drugs like diuretics, low-dose aspirin, allopurinol, febuxostat, and certain vitamin supplements can change uric acid levels. Tell your doctor about all medicines and supplements you are taking so the result can be interpreted correctly. Never stop or adjust a medicine on your own.
How long does the test take, and when can I expect the report?
The blood collection itself typically takes only a few minutes. In most private laboratories in Bangladesh, reports are available within a few hours to one working day, and many labs now send results by mobile text message or email. Samples sent to a central lab may take a little longer, so it is best to ask the laboratory staff when you give the sample.
Can heavy exercise or stress change the uric acid level?
Yes. Strenuous exercise can temporarily raise uric acid because it increases tissue breakdown and fluid loss. Extreme emotional stress can also produce changes in metabolism that influence the result. For the most accurate reading, try to avoid intense physical activity the day before and on the morning of the test, and tell your doctor if you have had any recent stressful or unusual physical strain.
Is a serum uric acid test safe during pregnancy?
A routine blood test is generally considered low-risk during pregnancy because only a small amount of blood is drawn. Uric acid levels may be checked if a doctor suspects pre-eclampsia or another pregnancy-related condition. The test alone does not diagnose anything, and a doctor must evaluate the result with your blood pressure, urine findings, and clinical symptoms. If your doctor recommends it, discuss any concerns with them before the test.
