California Data, Statistics, and Surveillance
State surveillance systems are based on reports of blood lead tests from laboratories. Ideally, laboratories report results of all blood lead tests, not just elevated values, to state health departments. States determine the reporting level for blood lead tests and decide which data elements should accompany the blood lead test result.
These data were collected for program management purposes. These data have limitations, and we cannot compare across states or counties because data collection methods vary across grantees. They are not generalizable at the national, state, or local level.
This is only state-specific data and is not a population-based estimate, so we are not able to compare states against one another.
The surveillance definitions and classifications used in these datasheets are explained on the standard surveillance definitions and classifications webpage.
