No they didn't. Because that wasn't what they were studying. They were studying the infectiousness.

They relied on *others* to do that kind of test.

>PCR is a proven fraud

No, it's not.

> not show anything or anyone is infected with anything

On the contrary: it does show that someone is infected with *something*. Something that is not only transmissible, but which it's even possible to measure *how* transmissible (see above study)

'PCR doesn't tell you if you're sick' but it *does* identify the presence of a virus. ie you can use it to measure whether infection occurred. Whether you get sick *from* the infection depends on your immune system and other factors.

the rest of the quotes are mostly just FUD
