Please note that families with children with elevated lead levels may move or change their address during the calendar year. The map below reflects the child’s address provided at the time of lead testing. If a child was tested more than once in a calendar year, the child’s address at the time of their highest venipuncture (blood drawn from the vein) result will be used to create the map. If no venipuncture was performed, the address at the time of the highest finger stick result will be used. It is important to note that the child’s address at time of testing is not always the same address where the child was exposed to lead.
