RE: That latest tweet...14 Jul 2020 16:48
I really do believe that everyone is reading far too much into the 2nd Tweet.
The last line of the introductory paragraph says it all for me: "We therefore conclude that surveillance should prioritize accessibility, frequency, and sample-to-answer time; analytical limits of detection should be secondary."
Avacta are merely pointing out that their upcoming Rapid Antigen Test will tick what a panel of experts deem to be the number one priority. I think that anyone then deducing that high sensitivity is in doubt, is making a huge and hopefully incorrect assumption.
