The National Animal Health Laboratory Network (NAHLN) is a network of animal disease diagnostic laboratories that provides ongoing disease surveillance, responds quickly to disease events, communicates diagnostic outcomes to decision makers, and has the capability and capacity to meet diagnostic needs during animal disease outbreaks.

Experts from APHIS, the National Bio and Agro-Defense Facility (NBAF), and NAHLN identified five key NAHLN facilities across the country to each host a scientist to work on this collaborative project.

NAHLN provides investigational and surveillance testing for high-consequence agricultural pathogens. View NAHLN response guidance documents.
