COVID-19 PCR Test protocol, Sensitivity, Specificity and therefore Operational False Positive Rate, and how the official figures are corrected for this

We're waiting for Jonathan Dench to read a recent response and update the status.

Dear Public Health England,

I have some strong scientific concern about COVID-19 testing and the handling of data by the UK Government.

Firstly no-specificity or sensitivity is provided which is completely unacceptable. It appears data is not being corrected for the Operational false positive rate of such tests. Current estimates of specificity from the literature are 95-99% ,this does not sound alarming at first, but once you account for test frequency and prevalence this is quite alarming, as it would provide an operational false positive rate of 90%. This can be confirmed from "with COVID death' data ie died within 28 days of positive PCR. If you compare current excess death with the average of the past 5 years with the governments estimates of COVID death, you get an Operational false positive rate of 70% for a sample with the highest pre-test probability of having COVID and therefore the lowest OFPR. This means the government statistics are meaningless without correction. This also means no mass indescriminate testing should take place as this would further worsen this problem. You should be doing a full investigation on this matter, as the Government draws us further into a pseudo pandemic.

What I am requesting:

Full PCR test protocol
Test sensitivity
Test specificity
How data is being corrected for Operational false positive rate.

If you cannot provide these then you should not be using PCR as a diagnostic test and a full investigation should be launched immediately.

Yours faithfully,

Dr Jonathan Dench

Dear Public Health England,

Please pass this on to the person who conducts Freedom of Information reviews.

I am writing to request an internal review of Public Health England's handling of my FOI request 'COVID-19 PCR Test protocol, Sensitivity, Specificity and therefore Operational False Positive Rate, and how the official figures are corrected for this'.

The response I received was as expected. Showing gaping incompetences in Public Health management within this country.

Running a testing program, in this way is misleading and dangerous. Not because, it is overestimating COVID on a population level. But because it leads to blatantly incorrect data being provided to the nation. This impacts dangerously two fold, people recognise its wrong and therefore decide COVID is a hoax etc and most importantly you cannot plan effectively if you do not understand your data set. Removal of false positives is not removing the ones you know were contaminated. It involves understanding your test adjusting the figures, its called conditional probability. It must be made on a population level. Positive tests does not equal number of cases. This ignorance of science is disgusting and someone must be held accountable. I am happy if you set up a meeting to explain why this is not correct. The error in your current data is simply abhorrent. Currently my analogy for this is that if mid battle of britain we decided not to use RADAR or the plotting tables and fly blind.
