About this Test:
The Renal Stone Analysis is a specialized laboratory test that determines the precise chemical composition of a kidney stone (renal calculus) after it has been passed or surgically removed. This test is the most important step in understanding why the stone formed and creating a targeted plan to prevent future recurrence.
✔ Determines the exact chemical makeup of the kidney stone.
✔ Identifies stone types: Calcium Oxalate, Uric Acid, Struvite, Cystine, etc.
✔ The single most important test for guiding specific dietary and medical prevention strategies.
✔ Requires the patient to collect and submit the dry stone to the diagnostic center.

Why is Analyzing a Kidney Stone So Important?
Passing a kidney stone can be an incredibly painful experience. Unfortunately, individuals who have had one stone are at a much higher risk (up to 50%) of forming another one within 5-10 years. The goal of this analysis is to break that cycle. Knowing the chemical composition of the stone allows your doctor to move from general advice (like drink more water) to a highly specific prevention plan.
What the Results Tell Your Doctor
This analysis will identify the type of stone, which points to a specific underlying cause:
- Calcium Oxalate Stones (Most Common): The most frequent type. Analysis helps confirm this, leading to recommendations to reduce oxalate-rich foods (like spinach, nuts, beets), lower salt intake, and maintain adequate hydration.
- Uric Acid Stones: These are linked to high-purine diets (red meat, organ meats) and acidic urine, often seen in people with gout. The prevention plan will focus on a low-purine diet and medication to lower uric acid levels.
- Struvite Stones (Infection Stones): These are caused by chronic urinary tract infections (UTIs). The analysis confirms this, and the treatment focus will be on completely eradicating the underlying infection.
- Cystine Stones: A rare, inherited genetic disorder where the kidneys do not properly reabsorb the amino acid cystine. This analysis is the primary way to diagnose this lifelong condition.
This report from the laboratory is the roadmap your doctor needs to create a personalized prevention strategy.
Frequently Asked Questions (FAQ)
Q1: Why should I get my kidney stone analyzed? I already passed it.
The analysis is not to treat the stone you passed, but to prevent the next one. Knowing its chemical composition (e.g., calcium oxalate vs. uric acid) is the only way for your doctor to give you specific dietary and medical advice to stop new stones from forming.

Q2: How do I collect the stone for the test?
You must catch the stone when you urinate. Your doctor may give you a strainer or gauze to urinate through. Once you have the stone, rinse it with plain water, let it air dry, place it in a clean, dry, sterile container provided by the diagnostic center, and bring it to the lab.

Q3: What if my stone is just tiny fragments or sand?
Collect as much of the material as you can, even if it's just gravel or sand. The laboratory can often perform the analysis even on small fragments.

Q4: Why does the test take 2 working days?
Kidney stone analysis is a complex process. It involves chemical analysis and often advanced methods like infrared spectroscopy (FTIR) to identify the exact crystalline structure of the stone's layers. This is a specialized test that takes time.

Q5: What is the most common type of kidney stone?
By far, the most common type of kidney stones are those made of calcium, primarily calcium oxalate.
