Children Tested

The children tested measures in the under 3 birth cohort evaluate all blood lead level (BLL) tests of children before their third birthday. Children are grouped based on the year they were born (the birth cohort year). Evaluating blood lead levels in children under the age of three is important because the first three years of life is the time when the brain grows the fastest and when the critical connections in the brain and nervous system are formed.

Measure Description
