Uric acid is a normal waste product formed when your body breaks down substances called purines. Purines occur naturally in your cells and in many foods.
Uric acid normally travels through the blood and leaves the body, mainly through the kidneys in urine. Problems can develop when production exceeds removal and the level stays elevated.
High uric acid can contribute to gout and certain kidney stones. However, a high blood result does not automatically mean you have either condition.

Where Does Uric Acid Come From?
Your body continuously renews and breaks down cells. This normal activity releases purines, which are then broken down into uric acid.
Food provides another source of purines. Certain animal foods, including organ meats and some seafood, contain substantial amounts.
However, uric acid is not simply something you “eat.” Your body produces it even if you avoid meat or follow a vegetarian diet.
This is why eliminating every purine-containing food is neither a realistic nor a complete approach to managing gout.
For food-specific advice, see our gout foods-to-avoid guide.
How Does the Body Remove Uric Acid?
The kidneys play a major role in controlling how much uric acid remains in the blood and how much leaves through urine. Some elimination also takes place through the intestines.
Your blood level reflects the balance between production and removal.
If your body makes more than it can eliminate, the concentration rises. Reduced removal is a common reason for this imbalance.
Having a high result does not, by itself, establish kidney failure. Kidney function needs to be assessed using appropriate tests and your medical history.

Uric Acid Terms You May See
Medical reports and gout articles use several related terms.
| Term | Plain-language meaning |
|---|---|
| Uric acid | A substance produced during purine breakdown |
| Urate | The form predominantly present in blood; often used interchangeably with “uric acid” in clinical discussions |
| Serum urate | The urate concentration measured in the blood |
| Hyperuricemia | An elevated blood uric acid level |
| Urate crystals | Solid deposits that can form when conditions allow urate to crystallize |
| Tophi | Lumps of accumulated urate crystals that can develop in longstanding gout |
These terms describe different things. A blood measurement is not the same as a measurement of crystal deposits.
What Causes High Uric Acid?
Several factors can influence production or removal:
- Inherited factors: genetics affect how the body handles uric acid.
- Kidney disease: reduced clearance can contribute to higher levels.
- Certain medicines: some diuretics and other treatments can raise uric acid.
- Alcohol and dietary patterns: these can influence uric acid balance.
- Other health conditions: excess body weight, metabolic conditions and increased cell breakdown can contribute.
Often, more than one factor is involved.
A high result is not proof that you have eaten badly. Equally, a healthy diet does not guarantee that your level will be low.
Our article on why diet alone may not be enough for gout explains this further.
How Is Uric Acid Connected to Gout?
When urate remains elevated, crystals can accumulate in and around joints. The immune system’s reaction to these deposits produces the inflammation responsible for a gout attack.
Symptoms may include sudden severe pain, warmth, swelling and marked tenderness. The big toe is commonly affected, but other joints can be involved.
There are three important distinctions:
- High uric acid does not always cause gout.
- A gout flare can settle while crystals remain.
- A blood result alone cannot diagnose every painful joint.
A clinician may use your symptoms, examination, blood tests and sometimes joint-fluid testing or imaging to establish the diagnosis.
See what causes gout attacks for the difference between the underlying disease and individual flare triggers.
When reviewing a commercial gout offer, check whether it distinguishes lowering a blood result from relieving pain or clearing deposits. You can read the seller’s product information here, but evidence for one outcome does not automatically establish the others.
Does High Uric Acid Cause Symptoms?
An elevated blood level often causes no noticeable symptoms. This is sometimes described as asymptomatic hyperuricemia.
Painful joints are symptoms of a condition such as gout, rather than a reliable way to estimate the uric acid level itself.
Similarly, feeling well does not tell you whether your result is high or low. Testing is needed to measure it.
If a routine test finds an elevated result, discuss it with your clinician. The next step depends on your history and overall health; it does not automatically mean you need gout medication.
What Does a Uric Acid Test Tell You?
A blood test measures the concentration of uric acid at the time the sample is collected.
It can support assessment and help monitor treatment. In some circumstances, a urine collection is used to investigate uric acid excretion, particularly when evaluating kidney stones.
A blood result does not directly show:
- How many crystals are present in a joint.
- Whether every episode of joint pain is gout.
- Which food caused a flare.
- Whether a particular supplement has cleared deposits.
Follow your laboratory’s preparation instructions and tell your clinician about medicines and supplements. Do not stop prescribed treatment to prepare for testing unless instructed.
What About a Normal Result During an Attack?
Uric acid can fall during a gout flare. A result within the laboratory range therefore does not necessarily rule out gout.
If gout remains strongly suspected, NICE recommends repeating the measurement at least two weeks after the flare has settled when the initial result is below 6 mg/dL.
Your clinician may also consider other diagnostic tests.
Is the Laboratory Range the Same as a Gout Treatment Target?
No. A laboratory reference range and a treatment target serve different purposes.
For someone being treated for gout, a common target is below 6 mg/dL, approximately 360 micromol/L. Some people with more severe disease need a lower target.
Ask which goal applies to you rather than relying only on whether the report flags the result.
Can Uric Acid Cause Kidney Stones?
Uric acid can also form stones in the urinary tract. Urine acidity and concentration matter, so the blood level does not tell the whole story.
Not all kidney stones contain uric acid, and not everyone with gout develops stones. Assessment may include urine testing or analysis of a passed stone.
Our guide to gout and kidney stones explores this connection.
What Should You Do After a High Result?
Start by asking what the result means in your circumstances.
Useful questions include:
- How does this compare with my previous results?
- Do I have symptoms or a history suggesting gout or kidney stones?
- Could medicines or another condition be contributing?
- Should the test be repeated?
- Do I need treatment, monitoring or lifestyle changes?
Avoid responding with extreme food restrictions or a product promising to “flush out” uric acid.

Frequently Asked Questions
Is Uric Acid Always Harmful?
No. It is normally present in the body. The concern is an imbalance that can contribute to crystal formation or other problems.
Is Uric Acid the Same as Urea?
No. They are different substances. A urea result cannot be used as a substitute for a uric acid test.
Can You Have High Uric Acid Without Gout?
Yes. Many people with elevated uric acid do not have gout. Results need to be interpreted alongside symptoms and medical history.
Can Drinking More Water Remove All Uric Acid?
No. Your body continues producing it, and removal depends on more than fluid intake. Maintain appropriate hydration, following any prescribed fluid restriction.
When Does Joint Pain Need Urgent Assessment?
A hot, swollen joint with fever or feeling unwell needs urgent medical assessment. Joint infection can resemble gout and should not be dismissed because you have had a high uric acid result.
