@Robbie You're not 'spreading awareness', you're misrepresenting or misunderstanding information. If you had any credentials to verify people should listen to you about something like this then fair enough but I don't think you should be posting misleading information about PCR tests when a) you're not qualified to do so b) you don't understand how they work. I personally also find it pretty depressing that you're bringing up the test accuracy of PCR tests at King's while just down the road from you there are nurses, doctors etc working their arses off trying to save people's lives. One of the reason's we're in such a dire position is because people have been spreading false information such as tests being inaccurate or even covid being a hoax. 1,800 registered deaths were recorded today- is that down to PCR testing cycles? Even after all the verifiable information about full hospitals and excess deaths do you really think that we're in this position due to false positives? Regarding your original PCR test claims, you do realise there are loads of different PCR tests for covid? Why don't you bother to actually look at the specific tests that you originally linked? The downloadable info is on their website (Altona Real Star, Cepheid GenExpert). You've taken two figures from two different documents to make your point. PCR tests aren't perfect but your claims above are misleading. Even the latest link you posted it says the following "Ct values cannot be directly compared between assays of different types due to variation in the sensitivity (limit of detection), chemistry of reagents, gene targets, cycle parameters, analytical interpretive methods, sample preparation and extraction techniques." Anyway, I wish your family well- hopefully lockdown will end very soon for all of us! :)
