Monitor exposure to nickel.

This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.

Nickel exposure is commonly evidenced by contact dermatitis.1 Nickel exposure may also affect pulmonary tissues, as seen by x-ray.2 In addition, nickel toxicity has been linked with central nervous system (CNS) depressant effects.1 Nickel is a component of many alloys; it is often used in metal plating and in the production of numerous electrical devices and in electronics. Exposure most often occurs in the industrial environment either through the inhalation of nickel dust or dermal contact with nickel compounds.
