The Dr. Katherine A. Kelley State 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 and districts, 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. Analytical data are used to monitor for agents harmful to the public health, identify the causes of outbreaks of disease, and assure that control measures (e.g., vaccines, antibiotics, environmental remediation, etc.) are effective.
