AAP Grand Rounds 14:44-45 (2005) Follow-Up of Elevated Screening Blood Lead LevelsSource: Kemper AR, Cohn LM, Fant KE, et al. Follow-up testing among children with elevated screening blood lead levels. JAMA. 2005;293:22322237.
Among United States children ages 1 year to 5 years, 2.2% have blood lead levels (BLL) over 10 µg/dL.1 The rate of elevated BLL among Medicaid-enrolled children is threefold higher than among other children.2 As a result, federal requirements mandate blood lead screening among Medicaid recipients. The first step in follow-up of an elevated screening BLL is confirmation by repeat screening. Investigators at the University of Michigan, Ann Arbor, and the Michigan Department of Community Health (MDCH), Lansing, studied Michigan Medicaid data to determine the proportion of children with elevated BLL who received follow-up BLL screening within 6 months.
Data from the MDCH, which receives results of all blood lead screenings performed in Michigan laboratories, were linked to Medicaid program files to identify Medicaid-enrolled children ages 6 years and younger with BLL over 10 µg/dL during an 18-month period in 2002
