FALSE: PCR tests do not diagnose COVID-19, but rather collect human genetic materials. Swab sticks used for taking nasal smear may damage brain membrane.

Explanation: PCR tests are especially sensitive towards pathogens; due to high accuracy of the results, PCR testing is even called the gold standard.

In order for the swab stick to reach the blood-brain barrier, it must pass several bony, various tissue layers and blood vessels. Each of them protects the mentioned barrier and its damage with a swab becomes practically impossible.

This method of testing had existed prior to the coronavirus outbreak and it has long been used in medicine for various purposes.
