Is universal screening for lead in children indicated? An analysis of lead results in Augusta, Georgia in 1997.

Pediatricians have a dilemma about whether they should do universal or targeted screening for lead in children. In order to determine whether we should continue our institution's present policy of universal screening, we analyzed 962 lead samples obtained by routine screening in the calendar year 1997, 83 children (8.6%) had elevated levels (over 10 mcg/dl) by capillary samples; of the 57 children who had follow up tests by venipuncture, 35 had abnormal levels making the incidence of elevated leads in our screened children 3.6%. Most of the abnormal levels were in African-American children living in two downtown zip codes. Based on recent AAP recommendations, in our community, targeted screening should replace universal screening.
