Universal Versus Selective Screening for Lead in Children

In his commentary in the February 1994 issue of Pediatrics, Dr Harvey recommends selective screening for lead in children based on the lack of evidence that a blood lead (BPb) level 10 µg is too low to justify universal screening.1 We agree that all screening programs should be continually evaluated so that timely refinements can be made. Such evaluations should be based on a fair representation of all available evidence.
