Overview of the Uric Acid Test
The Uric Acid blood test measures Uric Acid, usually present in blood predominantly as urate, providing information relevant to gout, kidney function and purine metabolism.
The test assesses 1 biochemical biomarker: Uric Acid.
Uric Acid is produced when the body breaks down purines.
Purines occur naturally within cells and are also found in foods and drinks.
Most urate is removed through the kidneys.
Blood concentrations therefore rise when production increases, kidney excretion decreases or both occur together.
Persistently raised serum urate is called Hyperuricaemia.
Hyperuricaemia increases the likelihood that monosodium urate crystals will form in joints and surrounding tissues.
These crystals cause the intense inflammatory attacks associated with gout.
However, a high Uric Acid result does not automatically mean somebody has gout.
Many people with Hyperuricaemia never develop joint attacks.
Likewise, serum urate can temporarily fall during an acute gout flare.
A result within the reference interval during an attack therefore does not completely exclude gout.
Uric Acid can also contribute to certain kidney stones.
Kidney function, medication, alcohol intake, body weight and metabolic health can all influence the concentration.
Where gout treatment is being monitored, serum urate targets can be lower than the general laboratory reference range.
The result should therefore be interpreted according to the reason testing was requested.
What Does the Uric Acid Test Check?
The test measures circulating Uric Acid or serum urate. This test measures 1 biomarker.
Uric Acid
Measures serum Uric Acid produced during purine metabolism, supporting assessment of Hyperuricaemia, gout risk, kidney handling and selected stone disorders.
Who May Benefit From the Uric Acid Test?
Uric Acid testing can be useful in gout, metabolic and kidney assessment.
People with symptoms suggestive of gout - Serum urate contributes to the overall diagnostic assessment.
People with established gout - Repeat levels can help monitor urate-lowering treatment.
People with recurrent kidney stones - Uric Acid can be relevant to selected stone types.
People taking Allopurinol or Febuxostat - Treatment commonly aims to reduce serum urate.
People with chronic kidney disease - Reduced renal clearance can increase Uric Acid.
People with an unexpectedly raised result on a health profile - Repeat testing can confirm persistence.
People using medicines that influence urate - Diuretics are one common example.
People with metabolic-health concerns - Hyperuricaemia can coexist with obesity, hypertension and insulin resistance.
How to Prepare
Serum urate can fall temporarily during an acute gout flare.
If gout remains strongly suspected despite a lower result during an attack, repeat testing after the flare has settled may be appropriate.
Symptoms and Reasons to Consider the Uric Acid Test
High serum Uric Acid itself can be asymptomatic until crystals produce gout or kidney stones.
Sudden severe pain in a joint - Gout commonly presents with intense acute inflammation.
A red, hot and swollen big-toe joint - The first metatarsophalangeal joint is a classic gout site.
Recurrent attacks of unexplained joint inflammation - Urate crystal disease is one possible cause.
Tophi or firm deposits around joints - Chronic urate deposition can produce visible nodules.
Recurrent kidney stones - Uric Acid is relevant to some stone disorders.
Monitoring established gout treatment - Serum urate guides long-term urate-lowering therapy.
A hot swollen joint can also result from septic arthritis, which requires urgent assessment.
A Uric Acid blood test should not delay medical evaluation of severe acute joint inflammation.

When Will I Receive My Results?
The current London Blood Tests turnaround for Uric Acid is approximately 1–2 days after laboratory receipt.
The test currently costs £58.
The assay is routinely processed once the specimen reaches the laboratory.
Understanding Your Results
A raised Uric Acid result indicates Hyperuricaemia.
This increases the likelihood of urate crystal formation but does not by itself diagnose gout.
A result within the laboratory range does not completely exclude gout, especially when testing takes place during an acute flare.
For people with established gout receiving urate-lowering therapy, clinicians often use a treatment target rather than simply aiming to remain below the laboratory upper reference limit.
A low result is generally less commonly clinically significant but can occur with some medicines or metabolic conditions.
Kidney function and medication history are important when interpreting persistent abnormalities.
Why Book With London Blood Tests?
London Blood Tests provides private Uric Acid testing for gout, renal and metabolic assessment.
Measures serum urate directly - The test quantifies the biochemical factor associated with urate crystal formation.
Useful in gout assessment - Results provide context alongside symptoms and clinical findings.
Useful for treatment monitoring - Serum urate is followed during urate-lowering therapy.
Relevant to kidney stones - Uric Acid can contribute to selected stone disorders.
Can complement kidney-function testing - Renal clearance substantially affects serum urate.
Useful for trend monitoring - Repeat measurements can assess long-term control.
Fast laboratory turnaround - Results are expected approximately 1–2 days after laboratory receipt.
Clear pricing - The Uric Acid test costs £58.
