Recently comparative testing on low antibody titer level samples were performed using the WNV SN and PRNT assays. This led to adjustments in our testing strategy. Moving forward, acceptable species for the serum neutralization (SN) assay are Canine and Equine ONLY. All mammals, avian, reptile, and amphibian species are acceptable for the plaque-reduction neutralization (PRNT) assay. Additional testing information can be found online.
