The Dr. Katherine A. Kelley Public Health Laboratory serves all communities in the state through the analysis of clinical specimens and environmental samples submitted by federal and state agencies, local health departments, clinical laboratories, health care providers, and water utilities. The Laboratory provides over 2 million test results on approximately 250,000 specimens and samples it receives each year. Although the Laboratory does not charge sister agencies or local health departments, the value of these testing services is over $7 million per year. Analytical data are used to monitor for agents harmful to the public health, identify the cause of outbreaks, and assure that control measures (e.g., vaccines, antibiotics, environmental remediation) are effective. The Laboratory is comprised of the following testing sections:



Biological Sciences – This section tests for infectious agents in humans, animals, food and water, and provides reference testing in support of epidemiological surveillance and outbreak investigations. Services exclusively provided by the Public Health Laboratory include:

·         Testing for emerging infectious diseases

·         Testing for surveillance and outbreak investigations

·         Animal testing for rabies

·         DNA fingerprinting of foodborne pathogens

·         Identification of BioResponse agents

·         Screening of all Connecticut newborns for the presence of 66 genetic, endocrine, and metabolic inherited disorders that cause severe mental and/or physical illness or death; through early detection and treatment, the adverse effects of these disorders can be mitigated.

Biomonitoring – This section provides testing services for Connecticut’s uninsured for the presence of elevated lead from exposure to lead-based paint, folk remedies, or other sources.

Environmental Chemistry – This section tests for over 100 toxic chemical agents in public drinking water supplies, private wells, rivers, lakes and streams, wastewater, spills, and soils. This section also provides analytical services for testing consumer products and other materials where there is a potential for exposure to hazardous materials such as lead-based paint. Other services include monitoring of the nuclear power industry, serving on the state’s nuclear response team, and maintaining preparedness and capabilities to respond to radiation emergencies. The Laboratory is also designated as the state’s Chemical Emergency Preparedness and Response Laboratory in the event of an accidental or intentional hazardous chemical exposure.
