This Act amends the Childhood Lead Poisoning Prevention Act to update the statutory definition of confirmatory blood lead testing for children under 16 years of age. The Act allows a confirmed elevated blood lead level to be established either through a venous blood lead test or through two capillary blood lead screenings collected within 12 weeks of each other, provided that the applicable lead reference value is met or exceeded. Two positive capillary blood lead screenings yield an effective specificity of approximately 99.75% when properly collected. This change is consistent with the Centers for Disease Control and Prevention surveillance case definition, reduces barriers to case identification and management, and requires conforming regulatory updates.
