Lead Poisoning Prevention
Request for Blood Lead Surveillance Information
The Minnesota Department of Health Blood Lead Surveillance database stores laboratory analysis and personal demographic data on all blood lead tests reported on Minnesota residents. Minnesota Statute Section 144.9502 subd. 1, Surveillance, states that the purpose of the system is to: " (a) monitor blood lead levels in children and adults to identify trends and populations at high risk for elevated blood lead levels; (b) ensure that screening services are provided to populations at high risk for elevated blood lead levels; (c) ensure that medical and environmental follow-up services for children with elevated blood lead levels are provided; and (d) provide accurate and complete data for planning and implementing primary prevention programs that focus on the populations at high risk for elevated blood lead levels." The information collected by the surveillance program does not reflect the entire Minnesota population and is only a subset of individuals who have been tested by the recommendation of their healthcare provider. Thus, it is inappropriate to calculate incidence and/or prevalence estimates for blood lead poisoning in the state from this surveillance data.
The blood lead surveillance data is classified as private and may be shared with certain governmental bodies. According to subd. 9, Classification of Data, "...data collected by the commissioner of health about persons with blood lead levels, including analytic results from samples of paint, soil, dust, and drinking water taken from the individual's home and immediate property, shall be private and may only be used by the commissioner of health, the commissioner of labor and industry, authorized agents of Indian tribes, and authorized employees of local boards of health for the purposes set forth in this section." Considering that the information provided is private, it is recommended that when mapping the blood lead surveillance data using geographical information systems, that data points be randomly distributed across geographical areas so that an individual's location may not be determined inadvertently. In addition, it is recommended that no less than ten data points be mapped in one geographical area so that identification of a particular location is prevented.
Due to ongoing data quality assurance efforts, the surveillance data is subject to change. Data reports are generated from the current status of the database, so future reports may reflect slightly different results or trends dependent on the quantity of changes made.
