Overview of the Renal Stone Analysis Test
Renal Stone Analysis determines the chemical composition of a kidney or urinary stone, helping identify what the stone is made from and informing investigation of why it formed.
The test assesses 1 specialist laboratory marker: Renal Stone Analysis.
Kidney stones form when substances normally dissolved in urine become concentrated enough to crystallise and grow.
Several different chemical types exist.
The most common are calcium oxalate stones.
Other stones can contain calcium phosphate, uric acid, struvite, cystine or mixtures of several components.
Stone composition matters because different stone types have different underlying risk factors.
For example, uric acid stones are associated with persistently acidic urine and selected metabolic conditions.
Struvite stones can develop in association with urinary infection caused by urease-producing bacteria.
Cystine stones are associated with cystinuria, an inherited disorder of amino-acid transport.
Knowing the stone composition can therefore guide additional metabolic investigation.
A person with recurrent calcium-containing stones may benefit from blood Calcium, kidney-function testing and a dedicated 24-hour urine evaluation.
Stone analysis also helps guide prevention.
Fluid intake, dietary advice, medication and urine-pH strategies can differ according to stone type.
The test requires a physical stone or stone fragment that has been passed naturally or removed during a clinical procedure.
It is not a blood or urine test.
What Does the Renal Stone Analysis Test Check?
The test determines the chemical composition of a submitted kidney or urinary stone. This test measures 1 specialist marker.
Renal Stone Analysis
Identifies the chemical constituents of a submitted renal calculus, helping classify the stone and guide investigation of the metabolic or infectious factors contributing to formation.
Who May Benefit From the Renal Stone Analysis Test?
Stone analysis is useful whenever an actual kidney stone or fragment has been recovered.
People who have passed a kidney stone naturally - Analysis can establish its chemical composition.
People who have had a stone removed surgically - A recovered fragment can provide information about underlying stone type.
People with recurrent kidney stones - Composition helps guide metabolic investigation and prevention.
People with a first stone at a young age - Unusual or inherited stone disorders may require further assessment.
People with a family history of recurrent stone disease - Composition can help identify inherited risk patterns.
People with suspected uric acid stones - Chemical analysis can confirm whether uric acid is present.
People with recurrent urinary infections and stones - Struvite composition can indicate infection-associated stone formation.
People with suspected cystinuria - Cystine stone identification can trigger appropriate specialist evaluation.
How to Prepare
Only actual stone material can be analysed.
Do not submit mucus, blood clots or unrelated material as a renal calculus specimen.
Symptoms and Reasons to Consider the Renal Stone Analysis Test
Stone analysis is performed after a stone has been recovered rather than because of symptoms alone.
A kidney stone passed in the urine - The recovered material can be submitted for composition analysis.
A stone removed during ureteroscopy or another procedure - Surgical fragments can usually be analysed.
Repeated episodes of renal colic - Recurrent stone formation warrants investigation of stone type.
Blood in the urine with confirmed stones - Composition can help inform prevention after acute management.
A history of multiple stone procedures - Identifying the dominant composition can guide further metabolic assessment.
An unusual stone appearance or family history - Chemical analysis can identify less common stone types.
Severe flank pain, fever, chills, vomiting, inability to pass urine or symptoms suggesting an infected obstructed kidney require urgent medical assessment.
Stone analysis is used after material has been recovered and does not replace imaging during an acute episode.
How to Book Your Renal Stone Analysis Test
Renal Stone Analysis can be booked privately once suitable stone material has been recovered.

Your authorised report is delivered securely and can guide further metabolic or preventive investigation.
When Will I Receive My Results?
The current specialist laboratory turnaround for Renal Stone Analysis is approximately 10 days after laboratory receipt.
The analysis requires specialist assessment of the physical and chemical composition of the submitted calculus.
The current London Blood Tests catalogue lists Renal Stone Analysis at £247.
Understanding Your Results
The laboratory report identifies the chemical substances present within the submitted stone.
A calcium oxalate result is the most common finding and can be associated with several dietary, urinary and metabolic factors.
A calcium phosphate stone can be associated with higher urine pH and selected metabolic disorders.
A uric acid stone can form when urine remains persistently acidic.
A struvite stone suggests an association with certain urinary infections.
A cystine stone raises concern about cystinuria and usually warrants specialist metabolic assessment.
Many stones contain mixtures rather than one pure chemical substance.
Stone composition does not by itself identify every cause.
Blood and urine testing may still be required to assess Calcium, Uric Acid, kidney function, urine pH and 24-hour urinary mineral excretion.
Why Book With London Blood Tests?
London Blood Tests provides private specialist analysis of recovered kidney stones.
Identifies the actual stone composition - The laboratory determines which minerals and compounds make up the calculus.
Supports personalised prevention - Different stone types require different preventive strategies.
Useful after a first recovered stone - Composition provides valuable baseline information.
Particularly useful in recurrent stone disease - Repeat stone formation warrants more detailed metabolic assessment.
Can identify uncommon stone types - Cystine, struvite and uric acid stones can require specific management.
Can guide additional blood and urine testing - Further investigation can be targeted according to stone type.
No blood draw is required - The test analyses the actual recovered stone.
Clear pricing - Renal Stone Analysis costs £247.
Private Renal Stone Analysis Test in London
London Blood Tests provides private analysis of kidney stones or stone fragments recovered naturally or during a medical procedure.
The test costs £247 and assesses the composition of 1 submitted renal calculus specimen.
Results are expected approximately 10 days after laboratory receipt.
Stone composition can guide further investigation and preventive management but does not replace metabolic testing where recurrent stones occur.
