It conducts tests for infectious diseases threatening people, livestock and wildlife, as well as for hazardous materials and pollutants in our water, air and milk. It also tests for alcohol and drugs in DWI criminal cases and for autopsy cases. Over the course of a regular year, the lab performs more than 350,000 tests on nearly 80,000 samples. We are a member in good standing of Association of Public Health Laboratories (APHL) and currently hold several additional accreditations and certifications.
