This map shows the percentage of children that reside in each New York State county, excluding New York City, who were tested for lead and identified for the first time within the specified time period to have elevated concentrations of lead in their blood. An elevated blood lead concentration of ≥ 10 mcg/dL is defined by the federal Centers for Disease Control and Prevention as the level requiring public health intervention. Under current NYS Public Health Law and implementing regulations, health care providers are required to test all children for lead at or around age one year and again at or around age two years. Health care providers are also required to assess all children age six months to 72 months of age at least once annually for lead exposure, with blood lead testing for all children found to be at risk, based on those assessments.
