How SARS-CoV2 Antigen Rapid Tests work (Covid-19 Testing)

Mine gave my positive in like 30seconds

Hello, thank you for providing such a great explanation video about how antigen rapid tests work. Because of that, may I ask you would it be okay if I take a few screenshots of this video as to use them when I explain about lateral flow essay?

Can you imagine natural selection somehow preventing the COVID virus from sticking to the primary antibodies in these tests?

All BS 😂

Hello, i am doing an assay of point of care tests and was just wondering which surface marker of the virus does the first line of antibodies bind to

Thank you 👍

Still don’t understand when binding means and I gold is important

So what's the function of second line..

this test is so genius

Question: What if you put in blood as a sample instead?

What if it takes longer than 15 minutes to form the second line, is the result still positive?

You are perfect thanks 😊

How one line color but another line is blur what it's that mean?

How do you explain weak lines

3000ml xl essential cold air oil diffuser add 10 drops of oregano oil 100% daily close bedroom door so mist stays in room run everyday and night for 1 month you have to kill the bacteria thats in your blood and in your skin thats making you still sick and 1 coq10 400mg daily. i helped alot of people it works 100%.please share thanks!!!

Of all the times ive taken tests, todsy is the first I've tested positive lol

Thanks dear
I'm gonna buy a test kit and your video makes it the simplest way
Bless you

I got red line C but mass of red smudge @ T 🤔

What is the C line is dark and the T line has a faint pink line, like mine does right now?

Amazing job.

Any particular reason it’s called the antigen test and not the virus test?

Are you positive if there’s a line when the open the test up?

What happened when I got 3 lines on mine 😳

Thanks, quick and clear!

Fantastic explanation! I absolutely adore this

Clear explanation. Thank you!

Hi, i just did my rat test, and is result the test line is dark and visible but the c line is visible but not dark.
What is it mean

Hi, this is a brilliant video. What software did you use to produce it?

I very much appreciated this simple explanation, as well as your interaction with viewers questions. From a COVID patient, thank you!

This was the best explanation I’ve seen. Thanks!

The rapid test is 50 percent accurate at best

Amazing explanation thank you! Yours combined with Wired's, clears it all up

why do we need to wait 15 minutes for results even if the control line is visible?

Business.

Thank you! for explaining this to me in how it works it was a great help.

How does an invalid result work? T line but no C line

Ok but how do you get the sample on? You spit on it?

What if it show 2 lines but one is faded

Hi Henrik, I got tested positive today. There were instant 2 lines, I redid and they are the same. I’m also having covid symptoms. Do you think an ordinary cold can come out positive on the test results?

No one talks abt this anymore...they are now talking abt nuclear test!! Stuvi

My son's name is Henrik as well

Hey, thanks for the info., I actually wanted to ask that I did a rapid test yesterday, it came out as (non infective)...I don't know if that means positive or negative, Please tell me what does it mean?

Can it distinguish between SARS-CoV-2 antigens and other common human coronavirus antigens?

Very informative, thank you for the information

I tested today, It shows red on C line after few seconds It said negative for some times. And then after few min, the very faint T line appear slowly. And it is showing positive. Why does the C line appear red for the first and T line appear after few minutes?

Thanks for sharing your video, God bless.

And where is graphine oxide? On the tip of the swab..or??

Thanks heaps for this post. Helps me to clear doubts about whether I didnt wait long enough or had missed it.

Great vid. My only question is why do we need a secondary antibody line aka control line if the primary immobile antibody is enough to indicate the presence of the viral protein?
