Just what does the test measure anyhow? 

My recollection is a survey published in the AB Journal last year 
indicated many hives across the USA have some AFB spores present 
but not neccesarily have a full blown foulbrood problem. 

The test might measure some threshold of spores present but is that 
threshold a problem level that requires intervention? 

So it's unclear to me what a postive test would be telling the user  to 
do.... we certainly don't need more beekeepers dumping antibiotics 
into hives as a preventative FB treatment.

I'm not sure I would be burning frames either based on a "test" before 
I actually saw infected larvae.
