How Would Veterinary Diagnostic Labs Test for African Swine Fever?

What would African Swine Fever testing look like through the lens of our veterinary diagnostic laboratories? Interestingly, we know exactly what it looks like, because it’s already being done at sites such as the Animal Disease Research and Diagnostic Laboratory at South Dakota State University.
