Percentage of children in the target population tested for lead poisoning within the calendar year. The target population is determined by the number of live births in preceding years.
Prior to 2013, elevated blood lead levels refers to children receiving two consecutive blood lead test results of greater than 10 micrograms per deciliter within a six month period.
Starting July 5, 2012, the CDC lowered its reference value to 5 micrograms per deciliter; therefore, surveillance tables for 2013 and later include testing and confirmation at ≥5 micrograms per deciliter.
