"Dr Susan Hopkins, medical adviser to NHS Test and Trace, has said that
lateral flow tests [have] less than five per thousand false positives...!
I just heard her say this and the above is a partial quote from the
3 days ago the BBC reported that there had been 90,000 tests in
Liverpool and found 336 positives. Something does not add up - there
should be 450 false positives expected.
This is not a conspiracy theory or attempt to claim that COVID does not
exist - we are being very careful, following the rules wearing masks
etc. and will continue to do so.
But what is the explanation for these results ? I know that the LF test
only detects people that are actually infectious whereas the PCR test
detects any level of viral fragment traces*, but this would seem to
indicate that there are very few infectious people in Liverpool which
was one of the hotspots when we locked down again not very long ago.
TIA for clarification. Confused of Bedford
* another report I saw today from a court case in Portugal said “if
someone is tested by PCR as positive when a threshold of 35 cycles or
higher is used (as is the rule in most laboratories in Europe and the
US), the probability that said person is infected is <3%, and the
probability that said result is a false positive is 97%.”
I read some time ago some expert in PCR testing that you should not do
more than 30-35 cycles and that she would personally stick to 30
iterations, and that in the UK we are doing 40 !!!
