The first priority in managing any patient with detectable serum lead is to determine the source of exposure and to remove the person from it. The finding of any elevated serum or urine metal concentration in an asymptomatic person should prompt a thorough dietary, occupational, and recreational history, and radiographs where indicated to identify any source of ongoing exposure. Occupational or recreational histories in parents can also reveal a source of exposure for children.
