Efforts to prevent lead poisoning have focused primarily on secondary prevention because the cost of primary prevention in the form of environmental inspection and abatement of all homes and other sources of lead is prohibitive. This focus does not reflect the true importance of primary prevention.

Secondary prevention focuses on the early detection of lead poisoning. The CDC has devised screening criteria to determine which children are at high risk for lead poisoning; screening of BLLs should be carried out according to these criteria (see Workup). Medical evaluation, treatment, and environmental and public health follow-up are essential in individuals with elevated BLLs.
