NVSL Diagnostic Virology Laboratory

The Diagnostic Virology Laboratory (DVL) performs confirmatory and diagnostic testing for many domestic and foreign animal viral diseases, such as vesicular stomatitis (VS), highly pathogenic avian influenza (HPAI), virulent Newcastle disease, equine encephalomyelitis viruses (e.g. Eastern equine encephalomyelitis [EEE]), equine infectious anemia (EIA), bluetongue (BT), swine influenza, pseudorabies (PRV), and West Nile encephalitis. Maintaining expertise for these diseases and other viral agents is part of DVL's role in protecting the American livestock industry.

The DVL is a Reference Laboratory for the World Organisation for Animal Health (OIE) and a Reference Centre for the Food and Agriculture Organization of the United Nation (FAO).

The DVL also performs import/export testing, produces reference and other reagents, and administers relevant proficiency testing and laboratory approvals for selected viral tests (including avian influenza and Newcastle real-time reverse transcriptase (rrt) PCR) in laboratories belonging to the National Animal Health Laboratory Network.
