CPT Codes
82570; 83921
Preferred Specimen
"Urine
"
"
Minimum Volume
"2.2 mL
"
"
Instructions
"Maintain specimen at room temperature.
Sampling time is the end of the shift at the end of the work week for industrial exposure monitoring. Metabolites with timing “end of shift at the end of the work week” (meaning four or five consecutive working days with exposure) are eliminated with half-lives longer than five hours. Such metabolites accumulate in the body during the work week; therefore, their timing is critical in relation to previous exposures.
