COBALT, WHOLE BLOOD

Mnemonic

COBALT WB

Guidelines

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