So a few on here had a discussion a few months ago now about the PCR test and if it's reliable enough to pick up live virus fragments or dead ones etc. Some were called out for been conspiracy theorists.

Thoughts? Have the authorities invented a better, more reliable test yet?
Several people, such as Heneghan, have been trying to make this point for many months but it often goes unheard. I’ll be honest, I’ve been guilty of chucking him into the ‘really?? That can’t be right, otherwise more people would know about it and be angry’ bracket previously, but sometimes, some of the things he and his like say, are actually scientifically sound and merit discussion.
Anyway, the take away is that 20k positive tests officially does NOT mean 20k people actually have, and are capable of spreading, SARS-cov-2, at that time.
Might be quite a high proportion, might be quite a low proportion. Who knows?
I do think this point is generally accepted by plenty in the scientific community but it’s not widely known amongst the public. People think that 20k positive tests mean 20k new people now have it (obviously plus the other 20 odd k who are untested or asymptomatic and the 500k or whatever it is, that have it but were tested a week ago etc)
Regarding the new mass testing of asymptomatic cases, surely this will have the same issue-finding loads of non-currently active cases and even driving policy, not to mention isolating lots of people unnecessarily.
Having said that, is it just a case that it’s preferable having those who MAY be positive isolate rather than risk them spreading it, (if they are positive but not above the threshold level for being currently infectious).
I don’t know how they fix this, unless it’s easy to insert a threshold level when interpreting the results?
And if it is that easy, and they’ve just not done it, then it begs the question, why?
