  • Cobalt:creatinine ratio

Monitor industrial exposure to cobalt

Urine, random
5 mL
1.5 mL

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.

Urine, 24 hr
  1. Measure total volume
  2. Mix specimen well
  3. Transfer a 5mL aliquot to a Transfer vial/tube with cap - 12mL (LabCorp)



Ambient (preferred) - 14 days

Refrigerated - 14 days

Frozen - 14 days
