NAHLN research and testing infrastructure primarily serves to:

• A. Provide immediate on-site veterinary care for farms
• B. Network certified laboratories for suspected foreign animal disease testing and confirmation
• C. Coordinate import/export quarantine at borders
• D. Manage detector dog deployments

Answer: (B)

NAHLN testing infrastructure is designed to connect certified laboratories so they can test and confirm suspected foreign animal diseases. This national network brings together state, federal, and university labs to perform initial diagnostics and provide definitive confirmation, enabling rapid and standardized results across the country. It supports timely surveillance, reporting, and coordinated outbreak response, with quality assurance and data sharing across jurisdictions. It isn’t about on-farm clinical care, border quarantine operations, or deploying detector dogs—those functions belong to separate components of animal health work. The primary role of NAHLN is to deliver a coordinated lab testing and confirmation pathway for foreign animal diseases.
