The Centers for Disease Control and Prevention (CDC) Lead Poisoning Prevention Branch (LPPB) compiles state surveillance data for children age <72 months who were tested for lead at least once between January 1, 1997 and December 31, 2005. This analysis uses the following surveillance definitions for all states:
To classify confirmed elevated BLLs, two elevated capillary or unknown tests (we assume unknown tests are capillary) must be drawn within 12 weeks (84 days). Once a child has had one confirmed elevated BLL, if in subsequent years he or she has another elevated test result, regardless of the test type, we include that child in the tables showing the number of children with confirmed elevated BLLs for each year he or she continues to have an elevated BLL test result (prevalence data). However, a child is counted only once for each year in which he or she is tested and has an elevated BLL. In a subsequent year, if a child with a confirmed elevated BLL has no follow-up test or only follow-up tests that are below 10 mg/dL, the child would not be counted with confirmed elevated BLLs for that year.
