Maybe I am missing something as I don't really get this.
By way of introduction this article goes on about how time consuming it is to inspect for AFB. Then it introduces the idea, which is a test kit that takes 30 minutes to get an answer, presumably testing a hive/cell that is suspect (i.e. has already been inspected). There are already test kits available for this (although I have never used one).
I'm all for new ideas and trying things out but I struggle to see how this is going to help us much. I would think a sniffer dog or the entrance swab test
@JohnF has developed would be comfortably superior to this.
