What network including the National Animal Health Laboratory Network (NAHLN)—network of diagnostic labs that provide ongoing data for NAHSS?

• A. NAHSS
• B. ARBONET
• C. NAHLN
• D. Veterinary diagnostic lab

Answer: (D)

The main idea is that NAHLN is part of a larger system of labs that handle animal-health testing and share results for ongoing surveillance. This broader network is the veterinary diagnostic lab network, which includes state, federal, and reference laboratories that perform tests and feed data into national surveillance efforts like NAHSS. NAHLN itself is a network of diagnostic labs, so the surrounding network that encompasses these labs is the veterinary diagnostic lab network. Other options either refer to the surveillance system itself (not the network of labs), a different specialized network (ARBONET), or a general type of lab rather than the network category. So the network that includes NAHLN is the veterinary diagnostic lab network.
