Calculus (Stone) Analysis by Automated FTIR (Urine Calculus)
This test identifies the composition of kidney stones (renal calculi). Knowing the stone type helps in developing a treatment plan to prevent recurrence. The analysis can detect common stone types such as calcium oxalate, uric acid, and struvite.
Calculus (Stone) Analysis by Automated FTIR (Urine Calculus) Package in Coimbatore Overview
Purpose of the Calculus Analysis by Automated FTIR Test
This diagnostic test is used to identify the chemical composition of a calculus (stone) — usually from the urinary tract (kidney, ureter, bladder), salivary glands, or gallbladder.
Understanding what the stone is made of helps determine:
- The underlying cause (e.g., dehydration, metabolic disorders, infections, etc.)
- Prevention strategies (e.g., diet, medications)
- Treatment planning (e.g., whether certain stones can be dissolved or require removal)
Advantages of Automated FTIR Analysis
- Highly accurate and reproducible
- Fast turnaround (compared to manual analysis)
- Non-destructive
- Detects mixed-composition stones
- Requires small sample size
- Fully automated = less human error
When is it Ordered?
- After stone passage or surgical removal
- For recurrent stone formers
- In cases of pediatric or early-onset stones
- When metabolic or genetic disorders are suspected
