Virology & Molecular Testing

The Virology Laboratory participates annually in the National Respiratory Virus Surveillance System program.

Specimens are collected from patients with symptoms of influenza in clinics and hospitals across the state and submitted for viral PCR testing. The influenza strains are identified and subtyped to provide information to the Centers for Disease Control and Prevention (CDC). This information is used to monitor outbreaks, emerging strains and to aid the World Health Organization (WHO) in vaccine development.

The SDPHL uses molecular methods to rapidly identify infectious disease agents. Modern analytical techniques like molecular diagnostics, are becoming increasingly popular with laboratories around the world. Molecular methods utilize DNA or RNA from a pathogen to confirm or exclude a diagnosis of disease.

Offered at this laboratory as well are serological tests to select viral agents, which may be found under “Serology” or “STI & Bloodborne Pathogens.” If you cannot find the test you are searching for, please refer to the service manual for a complete list of tests offered at the SDPHL.
