"And this is owned and operated by Rockefeller. This is part of the Barcode for Life Initiative to tag and identify all life forms. No longer will any life form be pure.

The video was shared more than 9,000 times in three weeks.

There are no magnetic particles on PCR testing swabs used on patients and no magnetic beacons that can track people or make them patentable, experts say. Magnets are sometimes used in a process to amplify genetic material collected during testing, but that happens away from the patient.

Swabs contain no magnetic or metal particles

The polymerase chain reaction test – or PCR test – has been a critical tool for identifying infections of SARS-CoV-2, the virus that causes COVID-19.

PCR tests are usually performed with a flocked swab that has a nylon microfiber tip and a plastic handle, according to Emily Travanty, laboratory director for the Colorado Department of Public Health and Environment.
