Expected Turnaround Time
2 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Test Details
Use
Monitor industrial exposure to cobalt
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.
Methodology
Inductively-coupled plasma/mass spectrometry (ICP/MS)
Reference Interval
• Environmental exposure: <1.0 μg/L
• Occupational exposure: BEI® (sampling time is end of shift at end of work week): 1.0 μg/L1
Additional Information
Cobalt poisoning through chronic exposure may result in pulmonary fibrosis, cough, and dyspnea. Acute exposures are generally characterized by an allergic dermatitis.2 Cobalt is employed industrially in certain grades of steel and in tungsten carbide tools, and cobalt compounds are used as pigments in paints. In addition, cobalt is an essential element in man, supplied through dietary intake at an average of 280 μg/day. Although cobalt is found in the general environment, overexposure typically occurs in the industrial environment, primarily through the inhalation of cobalt dust and/or fumes. Cobalt exposure can also occur as a result of ingesting medications such as cobaltous chloride. Blood is the preferred specimen for measuring acute or recent exposure.
