The Virology Laboratory of the Animal Health Diagnostic Center provides a comprehensive portfolio of tests as well as consulting services in the area of veterinary virology. Diagnostic tests offered include assays to detect viral infections or host responses to infection through the use of tests that isolate and detect viruses in cell culture, that detect viral antigens or nucleic acid (RNA and DNA), and that detect and quantify antibody responses to infection and/or vaccination. Consultative services involve test interpretation, testing strategies, sample selection as well as infection control strategies. These services are available to private practitioners, other testing laboratories, agribusinesses, and researchers in university and government settings.
