Specificity5 May 2021 16:06
I'll try to ellict some constructive debate - i'm not for one minute entertaining a battle between the AVCT test and visitect; as others have mentioned there could be more than one sovereign test and they may both be chosen and or suited for different settings.
AVCT BB are rightly proud of the sensitivity that was determined in their last round of tests. Could truly be a game changing technology. What struck me as well as the high sensitivity was the specificity of 99.0% especially in light of Visitects 100% on a large scale trial.
Please correct me if I'm wrong, is this everyone's understanding of the specicificy of Innova, AVCT, Visitect
Innova 99.6%
AVCT 99.0%
visitect 100%
Appreciate this is a generalisation not comparing CT values etc.
One of Deeks (pardon my language) main issues was false positives with Innova.
If the AVCT test is 99.0 will there be a greater instance of false positives to balance against a greater accuracy in positive detection?
If Visitect is less accurate than Avacta at identifying positives at lower viral loads would the govt favour less false negatives as a means to reopening in certain settings (schools + universities spring to mind)
As I said only opening for debate and I am by no means an expert on S+S - I don't care what test is chosen as omega will make either
As highlighted above if the figures I have laid out are wrong please feel free to shoot me down.
