title: Lead screening by family physicians.
abstract: Blood lead level tests, by the finger-prick micromethod, were given to 333 children in a primary care practice. On initial testing, 18.6 percent of children had lead levels between 30 and 39 microng/100 ml and ten percent had lead levels of 40 microng/100 ml or greater. In the latter group, only 2.7 percent had levels in that range when retested with venous blood samples. Socioeconomic status, as determined by census tract residence, correlated with evidence of undue lead absorption. Of the children tested from socioeconomic Group I (I is highest), 3.4 percent were affected, as opposed to 60.0 percent of the children residing in Group V census tracts.
