Ian -
Boot is talking about an antigen test - As I’m sure your aware the throat swab test you refer to is a PCR test which can detect the virus from a few days after infection , this test requires the swab sample to be sent to a lab for analysis where it takes between 45mins - 4 hours to produce results so a drawn out procedure .
The antibody test (which there are hundreds , and most very inaccurate), will only detect the virus once the patient has been infected for a number of days , if recently infected it won’t detect whether the patient HAS the virus, and therefore whether he/she is infectious / shedding it as the body wont have produced antibodies to fight the infection at the initial stage of infection, and as you rightly point out this test is all over the place in terms of accuracy as no one seems to be able to get it right .
The antigen test , which I’m astonished has hardly been touched on by the media was successfully developed in 2016 to test for the Zika virus, it never found its way on to a lateral flow test as the outbreak petered out thus rendering the test useless , however the scientists have successfully reworked it in the lab, as we speak it’s being applied to a lateral flow test ( think pregnancy test) , they will know in a few weeks if it has been successfully transferred, the company that’s developed it has confirmed the test doesn’t cross react with closely related viruses thus making the test highly accurate and fast , it will be an affordable saliva test producing results in a matter of minutes.

They have a collaboration with one , and are talking to two other pharmaceuticals to mass produce the test in the billions - IF IT WORKS , which I hope for everyones sake it does , it will not only get the world back to work , you won’t set foot in an airport lounge anywhere in the world without having been tested as it will be the only way to get the planes back in the sky ...... with respect the to the fever detection equipment , there is of course currently a boom in sales so one would think we will benefit , however IF , this test comes on stream , (and if this doesn’t another one will) , the fever detection machine will quickly become akin to the office fax machine .....so a limited revenue stream in respect of Covid 19 ........AIMHO
