Calculi (Stone) Analysis : 0099460

Mnemonic: CALCULI

Methodology: Quantitative Reflectance Fourier Transform Infrared Spectroscopy/Quantitative Polarizing Microscopy
Performed: Sun-Sat
Reported: 1-4 days
Specimen Required: Collect: Calculi specimen.

Specimen Preparation: Air-dry calculi and transfer to an ARUP Standard Transport Tube. Larger calculi specimens may be transferred to a clean, empty urine cup (150 mL) or similar container.

Storage/Transport Temperature: Room temperature. Also acceptable: Frozen or refrigerated.

Remarks: Calculi specimens transported in liquid or contaminated with blood require special handling which will delay analysis. Specimens that are wrapped in tape or embedded in wax will delay or prevent analysis and should not be submitted.

Unacceptable Conditions: Any collection or shipping container with a needle attached.

Stability (collection to initiation of testing): Ambient: Indefinitely; Refrigerated: Indefitnitely; Frozen: Indefinitely

Reference Interval:
By report
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.
Note: Calculi samples that are transported in liquid and received wet or bloody will be dried for 48-72 hours prior to analysis.
CPT Code(s): 82365
