This PCR test farce has been going on since Mar 2020.

Whilst extending the number of cycles beyond 40 may increase the sensitivity of the assay, it
may also increase the risk of false positivity due to non-specific amplification.

This looks like the Fed Govt uses 40 as the “OK” parameter, so all these new “cases” are 96% bullshit.

Even the Delta strain.😁

This next bit is important to understand. Queensland Health, or the rest of Australia for that matter, does not understand this concept. but it is up on the Fed Govt website.

“Analytical accuracy of the PCR is therefore very high but clinical accuracy of the PCR is a function of the prevalence of SARS-CoV-2 in the population being tested. A higher prevalence of SARS-COV-2 in the population, increases the pretest probability and the likelihood for detecting SARS-COV-2 RNA. This is reflected in a higher positive predictive value for the test. Conversely, even a very specific test will have a reduced positive predictive value if the population being tested has a very low prevalence of SARS-CoV-2.

For example, if a test with a specificity of 99% is used to test symptomatic passengers on a cruise ship where the likelihood of infection is 50%, the positive predictive value is 99% (i.e. for every 100 people with a positive test result, 99 people will have SARS-CoV-2 infection but 1 person without infection will have a false positive result).

However, using the same test, if a low risk asymptomatic population is tested where the likelihood of infection is 5 in 10,000 (i.e. 0.05%), the positive predictive value is 4.3% (i.e. for every 100 people with a positive test result, four to five will have SARS-CoV-2 infection but 95-96 people out of those 100, without infection, will have a false positive result).”

According to: https://www.qld.gov.au/health/conditions/health-alerts/coronavirus-covid-19/current-status/statistics#casesummary

There have been 2,854,125 tests done in Queensland which resulted in 1,686 “cases”.

Even if all those were certain positives, that equates to 0.059%. We can take that as the “likelihood of infection”. So, according to the Fed Gov website citing 0.05%, it must mean 96% of those Queensland tests were “false positives”.

So only 68 people out of the 1,686 “cases” reported in Queensland so far are probable positive for SARS-CoV-2. If they are fit and healthy individuals an illness that results from a certain positive diagnosis has a 99.74% chance of full recovery, without any medical treatment.

What’s the fuss all about?
