- Abstract
ABSTRACT Objective: To evaluate the accuracy of the verbal lead risk assessment tool in identifying the presence of measurable blood lead levels (BLL) in children. Design and Sample: A retrospective analysis comparing results of a verbal lead risk assessment tool intended to identify elevated BLL in children with actual capillary fingerstick lead screening laboratory data. Three hundred and forty-nine children aged 5 years and younger enrolled in Head Start during the 2008-2009 school year were evaluated. Sixty-nine children had complete data and were included for final analysis. Measures: Results of the verbal lead risk assessment and laboratory capillary fingerstick BLL. Results: All 69 children had measurable BLL. The Pass group, 84.3% of the sample, had BLL scores of 2.2±1.5 μg/dl, while the Fail group, 15.7% of the sample, had BLL scores of 1.5±0.65 μg/dl. There was no significant difference in BLL between children that passed the verbal risk assessment and those that failed ( p>.05). Conclusions: The verbal lead risk assessment did not accurately predict measurable BLL in children. Universal BLL screening for children is necessary to identify low levels of lead so that parents and caretakers of children can be notified and assisted in identifying and eliminating sources of lead exposure.
