Serum cobalt levels can be used in the assessment of occupational exposure or toxic ingestion and is the preferred specimen type for evaluating metal ion release from metal-on-metal joint arthroplasty. Serum cobalt levels may be increased in asymptomatic patients with metal-on-metal prosthetics and should be considered in the context of the overall clinical scenario. Symptoms associated with cobalt toxicity vary based on route of exposure, and may include cardiomyopathy, allergic dermatitis, pulmonary fibrosis, cough and dyspnea.
