New Mad Cow scare in US announced today
The first two tests were screening tests. They are less accurate and much less expensive. The results tell you that that cow might have had the prions, and that you should do the more expensive test. The more accurate test came out negative. I still think they should run it again, but the cow probably was negative.
Just what does this mean? They tested it at two screenings and it was reactive!? ...ummm, hey, lets keep testing it until it comes up negative shall we.
