Use
Monitor industrial exposure to cobalt
Special Instructions
Not provided.
Limitations
This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration. Urine specimens that are highly dilute or highly concentrated are generally not suitable for monitoring. The World Health Organization has guidelines for acceptable creatinine concentration limits: >0.30 g/L and <3.00 g/L.

Collection Instructions
Sampling time is end of shift at end of work week. Metals with timing “end of shift at end of work week” (meaning four or five consecutive working days with exposure) are eliminated with half-lives longer than five hours. Such metals accumulate in the body during the work week; therefore, their timing is critical in relation to previous exposures. Optional protocol: Instruct the patient to void at 8 AM and discard the specimen. Then collect all urine including the final specimen voided at the end of the 24-hour collection period (ie, 8 AM the next morning). Avoid contact with metal during collection. Screw the lid on securely.
Storage Instructions
Maintain specimen at room temperature.
