Specimen Required
Patient Preparation
 
Collect
Calculus 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. 
Unacceptable Conditions
Any collection or shipping container with a needle attached. 
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. 
Stability
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. Gross description may not be consistant with the composition determined by FTIR analysis.

Note
Calculi samples that are transported in liquid and received wet or bloody will be dried for 48-72 hours prior to analysis.
