Oxford University Says PCR Swab Tests for COVID-19 Return False Positive Results

New research from the University of Oxford’s Center for Evidence-Based Medicine and the University of the West of England found that the swab-based technique used for most COVID-19 testing is at risk of returning “false positives” since copies of the virus’s RNA detected by the tests might simply be dead, inactive material from a weeks-old infection. They say that patients infected with COVID-19 are typically only infectious for a week or less, tests can be triggered by virus genetic material left over from a weeks-old infection. Professor Heneghan warned of “the dangers of isolating non-infectious people or whole communities” based on the flaws PCR tests.

Governments and health officials, aided by the media, have been hyping the increased  number of “cases” of COVID-19, due to increased and invalid tests, in the interest of expanding their power. The number of deaths attributed to COVID-19, however, has not risen.

In the past, our reports raising questions about the accuracy of COVID-19 tests have been met with accusations of ‘fearmongering’ and spreading ‘misinformation’.

But not today.

That’s because new research from the University of Oxford’s Center for Evidence-Based Medicine and the University of the West of England has found that the swab-based technique used for most COVID-19 testing is at risk of returning “false positives” since copies of the virus’s RNA detected by the tests might simply be dead, inactive material from a weeks-old infection. Although patients infected with COVID-19 are typically only infectious for a week or less, tests can be triggered by virus genetic material left over from a weeks-old infection.

The team’s research involved analyzing 25 studies on the widely used polymerase chain reaction test. PCR tests use material collected with a swab – the most common type of test around the world, and especially in the US – then utilize a “genetic photocopying” technique that allows scientists to magnify the small sample of genetic material collected, which they can then analyze for signs of viral RNA.

What the researchers here have effectively found is that these PCR tests just aren’t sensitive enough to distinguish if the viral material is active and infectious, or dead and inert.

For those who desire a more comprehensive understanding of how these tests work, the chart below can be helpful.
