Section I: Trends in Childhood Blood Lead Screening

Unless otherwise stated, data are for children under age six years and for New York State, excluding New York City.

Under New York State (NYS) Public Health Law and regulations, health care providers in NYS are required to screen all children using blood lead tests at or around age one year and again at or around age two years1. Health care providers are also required to assess all children ages six months to 72 months at least once annually for risk of lead exposure, with blood lead testing for all children found to be at risk based on those assessments.

Young children are at highest risk for lead exposure. The purpose of screening is to identify children with elevated blood lead levels and, once identified, coordinate needed interventions to reduce sources of lead in children's environments and prevent further exposure. Information obtained from blood lead screening tests is also used to identify high-risk communities and populations and to target public health actions to improve lead screening and prevent lead poisoning.

Screening rates for a group of children born in a given year are based on blood lead testing data from subsequent years. For example, screening rates at ages one and two for children born in 2002 are based on blood lead tests that occurred from 2002 through 2005.

  1. For surveillance purposes, at or around age one is defined as 9 months to < 18 months and at or around age two is defined as 18 months to < 36 months. These one and two year age categories were designated based on an analysis that assessed the frequency of children's lead screening tests by month of age at tests.
