However, there are new concerns in some quarters that the LFT may be missing about 50% of the cases, as per the Liverpool University report 25th November on comparative testing of 3,199 patients. This showed that the LFT tests produced 25 positive cases, but that the PCR test produced 45 positive cases. What this report however fails to consider, in a significant shortcoming, is the false positive rate of the PCR test itself. Your own 1% FPR figure would mean that 32 of the 45 positive results would be false, meaning that the whole report’s concerns are misplaced . Thus, the report in fact would re-validate the LFT evaluation data from Porton Down, not cast doubt on it. In truth however, even if the LFTs were missing 50% of the cases, the numbers are still so far below the average daily PCR positive rates, that it still requires full and proper investigation.

The overall point is that there is such real concern over the testing programme in many quarters that it is vital to put this to proper comparative sampling.

On the BBC’s Politics Live programme broadcast on 7 December 2020, I specifically raised the issue of LFT tests and how they produced radically different results when compared to PCR tests. I issued a treble test challenge to the Government to clarify the position and confirm whether or not they still had confidence in the use of PCR tests. My suggestion was that 1,000 people or perhaps more should be tested on the same day, using the standard Government PCR test processed in more than one of its’ Lighthouse labs, the new Innova LFT test and a separate PCR test which should be separately analysed by an independent specialist laboratory testing facility.
