Key among these tools are highly sensitive tests, some available and some under development, that can detect prions even in asymptomatic individuals; currently BSE is diagnosed only after an animal has died naturally or been slaughtered.

其中几个关键工具就是高灵敏度的检测方法（有的已经上市，有的则还在研发当中），它们可以从没有症状的牛只身上侦测到普恩蛋白的存在；而目前BSE的诊断只有在动物自然死亡或屠宰之后才能确认。
