Figure 2 shows the percent of children who received at least one blood lead screening test by age 36 months and the percent of children who received at least two blood lead screening tests by age 36 months for children born in the years 1998 through 2004. The measure of at least one test by age 36 months allows NYS to compare its testing rate with the national measure newly developed by the federal Centers for Disease Control and Prevention (CDC). The measure of two tests by age 36 months assesses blood lead testing practices in relation to state requirements for universal blood lead testing at or around ages one and two years. Of children born in NYS in 2004, 82.8 percent received at least one blood lead test by age 36 months, while 40.8 percent percent received at least two tests by age 36 months.
Trend data show improvements in the percent of children receiving one or two blood lead tests by age 36 months. A 13.1 percent increase in the percent of children tested at least once by age 36 months was observed among children born in 2004 compared to children born in 1998 (73.2 percent of children born in 1998 compared to 82.8 percent of children born in 2004). For those children who received two lead tests by age 36 months, a significant improvement of 52.2 percent was observed among children born in 2004 compared to children born in 1998 (26.8 percent of children born in 1998 compared to 40.8 percent of children born in 2004).

- Birth Cohorts beyond 2004 are not included in this analysis because those children had not reached 36 months of age by 2007
