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

• The Children Tested is the number of children born in the birth cohort year and tested for blood lead level (BLL) before age three.
• The Children with Confirmed Elevated BLL is the number of children born in the birth cohort year and tested for blood lead level (BLL) before age three and had a confirmed result greater than or equal to 10 mcg/dL.
• The Percent of Children with Confirmed Elevated BLL is the percent of children tested that had Confirmed Elevated BLL result.

Currently IDPH only recommends children with an unconfirmed test result equal or  greater than 10 mcg/dL receive a followup test to confirm that result.
