Calculi (Stone) Analysis with Photo
Ordering Recommendation
Determine composition and appearance of calculi.
New York DOH Approval Status
Specimen Required
Calculus specimen.
Air dry calculi and transfer to an ARUP Standard Transport Tube. Larger calculi specimens may be transported in a clean, empty urine cup (150 mL) or similar container.
Room temperature.
Specimens wrapped in tape or embedded in wax will delay or prevent analysis and should not be submitted.
Calculi specimens that are transported in liquid and received wet or bloody will be dried for 48-72 hours, which will cause a delay in processing.
Ambient: Indefinitely; Refrigerated: Indefinitely; Frozen: Indefinitely
Methodology
Quantitative Reflectance Fourier Transform Infrared Spectroscopy/Quantitative Polarizing Microscopy
Performed
Sun-Sat
Reported
1-4 days
Reference Interval
Interpretive Data
Calculi are the products of physiological processes that yield crystalline compounds in a matrix of biological compounds and blood. Matrix components are not reported. The clinically significant crystalline components identified in calculi specimens are reported. Gross description may not be consistent with the composition determined by FTIR analysis.
