Molecular miracle

The Control line appearing is normal with just the buffer solution. It's designed to show enough of the sample has moved up the strip for the actual test to be accurate. Low pH seems to affect the false positive rate. https://www.sciencedirect.com/science/article/pii/S1201971221006548

Those people will trigger by anything.

Is it feasible to recover the gold?

The C line showing with just the buffer may be the origin of some of the false negative reports. I’ve heard (from a doctor) of the same thing happening with the PCR test when the swab isn’t done correctly.

Mark Gray

I spotted that, and lighting it was one of the first things that went through my mind.

That's a neat looking implementation of a DIN module.

I'll just tell them that a row of black dots means I'm a super-spreader.

Big Clive

I'm going to try just the buffer solution right now.

Big Clive

Yes.

Big Clive

The first couple of tests I did I didn't put the swab far enough back in the throat and the control line didn't appear, so the buffer solution alone doesn't appear to be enough (at least it wasn't for me).

Mark Gray

That's wild. Thanks Big Clive.

Well I certainly learned something new today! I was totally unaware that the flat-earth society needed any manner of trigger to show up, uninvited, and cause unlimited amount's of hate and discontent!

Clive, may I have permission to copy this video to show to some "doubters" that I know? Thanks

Chuck Kirchner

Best wishes for a speedy recovery. We can't have Clive's fans giving up the ghost AT ALL!! Cheers

I learned something new today.

Best way to use the word "trigger" in reference to flat-earthers involves a finger...

Scott Miller

I though the Sharpie indicated a hurricane forming. (Sorry, bad reference to a 2019 bit of US idiocy)

Maybe note that the test area of the strip has been marked with a sharpie to avoid low-IQers getting mad.

"Antipodes" triggers me. Bad LSD experience in Byron Bay.

I use the nose only veriety, jamming the swab up your nose until it almost comes out my ear is better than gagging on the throat veriety. Very interesting Clive and something else I don't have to wonder about. I can be the smartarse down the pub that knows how they work. Nice one Clive, thanks.

On a side note to this, I found out that those test strips are actually made of nitrocellulose aka gun cotton! I did try setting a dry one on fire, but it seems all the other chemicals on it stop it from getting "exciting"

There's at least one other version of the kits being distributed by the NHS. Same basic process but that one doesn't ask you to swab the throat, just the nose. No gagging, but the swab in that one is bigger and rougher, so it feels like your nose is being probed by aliens.

Fascinating, I kinda deduced this was how it worked but didn't know for certain.

Keep testing Clive. I had symptoms of a bad cold for 3 days, tested on day 1 with a -ve result. Did a routine test on the 3rd day as I was going to fly to Inverness and bang... The T line showed up as soon as the buffer/sample fluid hit it. Hope you feel better soon.

I was disappointed to find that the Control line doesn't actually test for the presence of DNA or anything, so simply using a couple of drops of neat buffer solution gives a result that looks negative. It makes you wonder how many infected people have failed to take a proper sample, but have then been greeted with a negative result.

The Binax test I used available in the States is a little different but essentially the same principle. This one had you just swab your nostrils. You placed the carrier solution directly on this cardboard card where there was a well and swirled the swab around a bunch. Then you folded the top of the card over onto the bottom part with the well leaving the swab in, it had a clever little cutout for it to rest horizontally. The top has the paper strip and then it soaks through. Takes 15 minutes. I was positive despite being vaccinated and the line was bright red at 7 minutes. Luckily it was a very light case and I now have a boost of immunity because of it. I work with the public so it isn't exactly surprising I contracted it.

Totally off topic but how cool are these! https://www.wago.com/gb/interface-electronic/energy-meters-mid

Oh darn, did I let slip.

Big Clive

Flat earthers or flatliners? XD

Tim Albers

Interesting and a nice change of pace. And "antibodies" slipped through once, unless you just meant you didn't use it in the title :)
