Yesterday’s post was a general overview of the reliability of the current PCR swab tests for coronavirus.

It concluded with two doctors recommending a saliva test instead.

However, how is it that some countries using the PCR tests came up with fewer coronavirus cases overall?

It has to do with the number of cycles they use.

This informative Twitter thread explains how Taiwan and Uruguay ended up with very low levels of infection. This was because of the number of PCR cycles they used:

The UK currently tests at 40 or 45, but Oxford University’s Professor Carl Heneghan says that we should be testing at 30 cycles instead. See tweets 7 and 8 below:

Prof Heneghan is not alone. Another pathologist also recommends a testing level of 30. See the cycles for Uruguay (35) and Taiwan (37-38) below. Beyond that, tests can become contaminated:

The conclusion follows. There could be an ulterior motive for using a higher number of cycles:

This is why many of us despair at our governments’ continuous coronavirus policies which are damaging our nations’ economies and our health.

More information about PCR testing will follow tomorrow.
