Avian influenza outbreaks can devastate poultry operations within days and trigger immediate export bans and mass culling once confirmed, making early on-site screening critical for containment. This antigen test detects active AIV infection directly from cloacal or respiratory secretions, giving farms and vets a fast first-line screening tool ahead of formal laboratory confirmation. Shelf life is 24 months when stored at 2-30°C, longer than most other kits in this range.
