Overview of the Uric Acid (Urine) Test
The Uric Acid (Urine) test measures the amount of uric acid excreted through urine, providing information about purine metabolism and renal urate handling.
The test assesses 1 renal and metabolic biomarker: Uric Acid (Urine).
Uric acid is produced when the body breaks down purines.
Purines arise naturally from cell turnover and are also present in foods such as some meats, seafood and alcoholic beverages.
Most uric acid is removed from the body by the kidneys.
Urinary measurement can therefore provide information about whether a person is excreting relatively high or low amounts.
This can be particularly useful during assessment of uric-acid kidney stones, recurrent stone disease or unusual serum urate findings.
Some people have high blood urate because their kidneys excrete too little.
Others can produce unusually large amounts of uric acid.
Urine testing can help differentiate these patterns when interpreted with serum Uric Acid and kidney function.
The specimen requirement matters.
The specialist laboratory uses a 24-hour urine collection for quantitative Uric Acid (Urine) measurement.
This allows total daily excretion to be assessed rather than relying on the concentration of one random sample.
Diet, alcohol, medication and recent gout treatment can influence uric acid handling.
The test does not determine the composition of a kidney stone directly.
Renal Stone Analysis is required when an actual stone is available.
What Does the Uric Acid (Urine) Test Check?
The test measures urinary Uric Acid excretion. This test measures 1 biomarker.
Uric Acid (Urine)
Measures the amount of Uric Acid excreted in urine, supporting assessment of purine metabolism, renal urate handling and selected kidney-stone disorders.
Who May Benefit From the Uric Acid (Urine) Test?
Urine Uric Acid testing can be useful during investigation of recurrent stones or abnormal urate metabolism.
People with recurrent kidney stones - Urinary Uric Acid can contribute to metabolic stone assessment.
People with confirmed uric-acid stones - Measuring excretion can provide additional metabolic information.
People with persistently high serum Uric Acid - Urinary measurement can help assess renal excretion.
People with gout and unusual urate patterns - Selected patients may benefit from urine studies.
People with a previous high urine Uric Acid result - Repeat testing can monitor response to treatment or diet.
People undergoing a comprehensive stone-risk assessment - Uric Acid can be considered alongside urine Calcium and other metabolic factors.
People with a stone available for analysis - Urine testing can complement direct Renal Stone Analysis.
How to Prepare
An incomplete 24-hour collection can make daily uric-acid excretion difficult to interpret.
Do not stop prescribed gout medication without medical advice.
Symptoms and Reasons to Consider the Uric Acid (Urine) Test
Urinary Uric Acid itself usually causes no symptoms unless it contributes to crystal or stone formation.
Recurrent kidney stones - Metabolic evaluation can help identify contributing factors.
Flank pain with a history of uric-acid stones - Urinary urate can be relevant to recurrence risk.
A confirmed uric-acid stone - Measurement can provide information about daily urate excretion.
Persistently high serum urate - Renal excretion can contribute to the overall pattern.
Repeated gout with complex urate management - Urinary studies are useful in selected cases.
Severe flank pain, fever, vomiting or inability to pass urine requires urgent clinical assessment.
Urine Uric Acid does not replace imaging when an obstructing kidney stone is suspected.

When Will I Receive My Results?
The current specialist laboratory turnaround for Uric Acid (Urine) is approximately 1 day after laboratory receipt.
The current London Blood Tests catalogue lists the test at £57.
A complete 24-hour specimen must be collected before laboratory processing begins.
Understanding Your Results
A higher urinary Uric Acid result indicates increased daily uric-acid excretion.
This can occur with increased purine turnover, dietary influences and selected metabolic conditions.
High urinary uric acid can contribute to uric-acid stone formation, particularly when urine is persistently acidic.
A lower result indicates less uric acid is being excreted.
In somebody with high serum urate, reduced renal excretion can contribute to Hyperuricaemia.
Interpretation depends on serum Uric Acid, kidney function, diet and medication.
The result should not be interpreted independently of the total 24-hour collection volume.
Why Book With London Blood Tests?
London Blood Tests provides private Urine Uric Acid testing for metabolic and kidney-stone assessment.
Measures daily Uric Acid excretion - The test evaluates renal urate handling.
Relevant to kidney stones - Urinary urate can contribute to uric-acid stone formation.
Complements serum Uric Acid - Blood and urine measurements provide different information.
Useful in selected gout assessments - Excretion patterns can occasionally guide a broader evaluation.
Uses a 24-hour urine collection - Daily output is measured rather than one random concentration.
Can complement Renal Stone Analysis - Stone composition and urine metabolism answer different questions.
Rapid laboratory analysis - Results are expected approximately 1 day after laboratory receipt.
Clear pricing - The Uric Acid (Urine) test costs £57.
