This video, was a monster. I've been working on it since the first cases were found outside of china and it has been an undertaking like nothing before. More graphics and animations than ever before and the amount of time in the lab and coordinating with people around the world was crazy. But I'm super thrilled with how it turned out and I hope you all enjoy! I'm posting this here early and will be setting it live tomorrow.

How Does COVID 19 Testing Actually Work?

Sars-Cov-2, the virus that causes Covid19 is easily the most defining feature of 2020. In the last 8 months the world has changed radically and there have been plenty of fumbles as countries struggle to deal with the chaos. One of the most important issues has been testing for the virus. In this video, I aim to demystify how that testing actually works down to the chemical level and show exactly how it's done. We'll be covering the viruses anatomy, as well as three types of test: PCR, LAMP and Antibody.

I love it, been waiting for a video that explains all this properly in depth! Although I’m an electronics engineer whos bio knowledge is very limited you did a fantastic job explaining it with the graphics & animations. It's cleared up a lot about it all for me.

Leif Clasen

Thanks for the hard work!

Not a big deal, but in case you want to be a bit more pedantic before going live, I think you want "COVID-19" instead of "Covid19" and "SARS-CoV-2" instead of "Sars-Cov-2". https://files.scoat.es/dKASbAr2.png Is it helpful for us to point out this kind of stuff before you make videos public?

Great video! Can’t wait for it to go public so I can share it.

In the video you mentioned that the only way out of the pandemic is through a vaccine and that the vaccine needs to be taken by everyone. I would love to see a video on the actual health risks of vaccines. I’d like to do my part, but I don’t exactly feel optimistic about a process(vaccine development) that normally takes more than a decade being compressed into a few months.

The video is public already, feel free to share. In terms of vaccines, making them is fairly easy and very fast. The old way of making vaccines where you slowly adapt a virus to be less dangerous, or inactivate it somehow is tedious, but that's ancient tech at this point. The modern version is using DNA /RNA based constructs that express a small number of the viruses proteins in your cells. These are very easy to design and extremely well tolerated and effective. They are also what is currently being rolled out for covid.
