What is a Kidney Stone Analysis Test?
A kidney stone analysis test helps determine the exact chemical composition of a kidney stone that has been passed naturally or surgically removed. The stone is examined using Fourier Transform Infrared Spectrometry (FTIR). This method analyses how infrared light interacts with the stone’s minerals to identify its components, such as calcium oxalate, uric acid, struvite, or cystine.
Knowing the stone composition helps your doctor understand why it formed and supports personalised treatment and prevention planning. The stone itself is the sample used for analysis.
What Does a Kidney Stone Analysis Test Measure?
The test identifies the minerals that make up your kidney stone, helping determine its type and likely cause:
- Calcium Oxalate or Phosphate Stones: Most common; often linked to dehydration, high urine calcium/oxalate, or dietary factors.
- Uric Acid Stones: Often related to acidic urine or high purine intake/metabolism.
- Struvite Stones: Commonly associated with urinary tract infections (UTIs) with urease-producing bacteria.
- Cystine Stones: Caused by an inherited condition called cystinuria.
This information helps tailor hydration targets, diet advice, and medications to reduce recurrence risk.
Kidney Stone Analysis Test: Who Needs It and Why It’s Done
What Symptoms May Call for a Kidney Stone Analysis Test?
Your doctor may recommend this test if you have:
- Severe back or side pain that comes and goes
- Pain during urination
- Blood in urine
- Frequent urinary tract infections
- History of kidney stones or unexplained urinary blockage
Who Should Get a Kidney Stone Analysis Test?
- People who have passed or had a kidney stone removed
- Those with recurrent kidney stones or a family history of stones
- Patients with metabolic disorders that increase stone risk
- Individuals with urinary tract infections linked to stones
Why is a Kidney Stone Analysis Test Done?
The test determines the cause of stone formation by identifying the stone’s chemical makeup. This supports a targeted plan for prevention, including diet modifications, hydration goals, and (when needed) medications.
Importance of a Kidney Stone Analysis Test
Kidney stones often recur, and prevention depends heavily on stone type. Stone analysis gives actionable insight into the mineral drivers of stone formation, helping you:
- Reduce recurrence through targeted diet and lifestyle changes
- Address infection-related stones appropriately
- Identify metabolic contributors and optimise long-term kidney health

Interpreting Kidney Stone Analysis Test Results
What Your Kidney Stone Analysis Test Results May Indicate
|
Stone Type |
Common Composition |
Key Risk Factors |
Recommended Preventive Measures |
|
Calcium Oxalate / Phosphate |
70–80% |
High urine calcium/oxalate/uric acid, low urine volume |
Increase fluids; maintain normal calcium intake; limit salt; reduce high-oxalate foods (spinach, peanuts, chocolate, tea) |
|
Struvite (Magnesium Ammonium Phosphate) |
10–15% |
UTI (often Proteus), high urine pH |
Treat UTIs promptly; monitor urinary pH; follow clinician guidance |
|
Uric Acid |
5–10% |
High uric acid, low urine pH |
Reduce purine-rich foods (red meat, mushrooms, alcohol); increase hydration |
|
Cystine |
<1% |
Inherited cystinuria |
Ongoing medical management; high fluid intake; specialist follow-up |
How Should You Prepare for a Kidney Stone Analysis Test?
- No fasting required; eat and drink normally.
- Collect the stone carefully: Store it in a clean, dry container.
- Keep it dry: Do not add fluids; do not tape the stone to the container.
- Label clearly: Add patient details and relevant clinical history if advised.
- Inform your doctor if you passed multiple stones or recently had stone surgery.
How Is a Kidney Stone Analysis Test Done? (Step-by-Step Procedure)
- Collection: The stone is placed in a clean, dry, leak-proof container.
- Inspection: The lab examines stone size, shape, and weight.
- FTIR Analysis: Infrared spectroscopy identifies mineral composition by analysing absorption patterns.
- Reporting: Results typically list the stone type and percentage composition of each mineral component.
Conditions That May Affect Kidney Stone Analysis Test Accuracy
- Mixing stones from different episodes may complicate interpretation.
- Incomplete collection or contamination (e.g., tissue) may affect analysis.
- Mixed stone types in a single kidney may produce combined results.
- Limited clinical history may reduce the usefulness of preventive interpretation.
Diseases That a Kidney Stone Analysis Test Can Help Detect
- Nephrolithiasis (Kidney Stones)
- Recurrent urinary tract infections
- Metabolic stone disease
- Cystinuria and other genetic stone disorders
- Hypercalciuria or hyperuricosuria (elevated urine calcium or uric acid)
