Definition: Percentage of children/youth ages 0-20 with blood lead levels at or above 9.5 micrograms per deciliter, among those screened, by age group (e.g., among California children ages 0-5 screened in 2013, 0.2% had an elevated blood lead level).
Data Source: California Dept. of Public Health, Childhood Lead Poisoning Prevention Branch (Aug. 2017).
Footnote: Medicaid and state regulations require that every child in a government-funded health program be screened for blood lead level at 12 months and again at age 2. When a blood test is missed, health care providers are required to screen the child at the first opportunity up to age 6. It is also recommended that health professionals screen any child or youth who exhibits symptoms of lead exposure, has known lead exposure, or is considered to be at risk for lead exposure. For children/youth who receive multiple tests, it is their highest blood lead level, and their county of residence at the time of their highest blood lead level, that is reported. Data exclude results determined to be false positives or clerical errors. The abbreviation S refers to data that have been suppressed because there were fewer than 20 children/youth screened for blood lead level.
