Bovine Viral Diarrhea Virus (BVDV) is one of the most economically damaging cattle diseases worldwide, causing reproductive losses, reduced milk yield, and increased susceptibility to other infections. This rapid antibody test helps identify previously exposed animals, supporting herd-level BVDV control and eradication programs that many countries now run at a regional level. Shelf life is 18 months when stored at 2-30°C.
