As a person who designs these tests, you explain it well for a layman. However, there are errors in your description. The secondary antibody doesn't attach a dye. Usually, the colour is produced by a colloidal gold particle (which is pink to red in colour), already attached to the second antibody. When the first zone is crossed, the urine interacts with the particle, but the particle is also moistened and begins to move WITH the urine sample and flow into the other zones where it is captured. You can confirm this by taking apart an unused pregnancy test, and a used one. You will see the "dye" (the gold particle) no longer is present in the first zone on the conjugate pad.

rickiex Urin is a great fertilizer. To add to that, Egypt as a civilization existed for an incredibly long time, the Pyramids were over 2000 years old by the time Alexander the Great invaded Egypt in 332 BC. After 2000 years of people regularly pissing on seeds in a civilization with excellent written records, this kind of stuff will get noticed.
Fun fact: the urine test you take at the doctor's office is no more specific than the one you take at home. The one that is more specific is the blood test (that's the one that can tell exactly how pregnant you are)
There are two types of blood tests: one that detects if there is HCG in the bloodstream, and one that detects how much. The latter can tell you how far along you are.
Bram06 I'm just wondering if it was random bullshit that happened to have some truth in it or if they experimented with different methods and found this one to be the most reliable. Hmm :p.
@@Subtlxty Not really , It's true the HCG ensyme is higher on victism of testicualr cancer but erally all men have those ensymes in smaller levels. So a sensitive enough test can show a false positive to all men. It's similar to how a sensitive drug test can show positive after you ate a bagel with poppy seeds because it can sense the very low level of opium.
This is the first time I have seen a TED - Ed video made by a Vietnamese educator. Now I feel so proud because I'm Vietnamese too. Go, Tien Nguyen, go!
That's a great thing though, you learn alot about human bodies as early as 13! Honestly as your parent I would be proud of you watching informative videos like this. You may not need it today, but it's great information to know, especially when you would need it sometime in the future.
I thought that at the beginning of the video she said "The earliest known pregnancy" and im like "wait HOW DID WE REPRODUCE BEFORE- oh its pregnancy TEST, ah ok I'm dumb"
To all the men who don't know why UA-cam recommended this video to us. I want to say that it's warning if we've got testicular cancer or not. So please watch it all and use pregnancy test to check if you're positive or not.
Ur graphics and the mini stories told....which are basically just the functions of hormones, are amazing....it can literally capture attention people till the very end😂😂 Great job
Vasilija Vujanovic i think only prostate cancer can be detected by it because the hormones are very similar to the hormones of a women that is pregnant
I saw that exact test in a history video but I thought it was something very faulty and couldn’t prove pregnancy but after watching this video, I was stunned
I had a friend once who had a pregnancy scare in like freshman year. She was broke but also needed to take it before her parents found out. I gave her 20$, I hope she’s doin well. She was really nice
Why are pregnancy tests so expensive in America. Like its just a women trying to see if she got pregnant after a accidental one night stand or wants a child
Mystik Basilisk I've been told the pill works by producing hormones that tricks the body into thinking it's already pregnant, thus preventing it from releasing an egg to get fertilised.
+Sara Wolverton The hormone that prevents ovulation isn't the same hormone that creates a positive pregnancy test. When a woman is pregnant, the elevated levels of estrogen in the blood prevent her from ovulation during her pregnancy. In the pill, the synthetic estrogen does the same exact thing (thus the idea of "tricking" your body into thinking it's pregnant and stopping ovulation). but the pill doesn't provide you with HcG, which is the actual hormone that makes a pregnancy test positive. HcG only comes about from the placenta after implantation. So you wouldn't produce a positive pregnancy test just from being on the pill.
I have noticed that inventions from before were practical, easy to find and zero waste eco friendly materials. Just awesome. 🎉 Hoping they will revive and teach us the ancient secrets . If only the great library weren't burned down, we would have discover more 🌺
A very nice and informative video. However the use of antibody-enzyme fusion proteins as described in the video is not the case with the vast majority of the home pregnancy tests. Most of the assays rely on gold- or latex nanoparticles to generate the visually detectable signals.
Thanks for this. This is so informative. I never knew about this. It's really amazing. And a useful video. People must have found it beneficial. Keep sharing such videos.
I once had to take a pregnancy test because of my operation I was happening and it came back negative and I wondered how it could work (the pregnancy test)
Is it possible for a test to show 1/2?. Like the urine pass the first negative line and stop at the middle before the second positive line?. Any ideal or polite explanation will be appreciated. Thanks u

This is a good question...
It is possible to get pregnant even on the pill, it is just far less likely. Hmm.
Northflower OwO Mystik Basilisk if you take antibiotics while on the pill/implant, it stops it from working. So yes, you can.

When a woman is pregnant, the elevated levels of estrogen in the blood prevent her from ovulation during her pregnancy.
