A teardown of an advanced pregnancy test has made a buzz subsequent to uncovering it contained a standard paper test, like those utilized by GPs.
The examination has brought up issues about whether the additional expense of computerized pregnancy tests is legitimized.
Some state the hardware offer ladies a more clear response however others highlight the e-squander made by computerized test packs.
The experiment additionally found the advanced test contained a chip more impressive than early home PCs.
In any case, the hardware themselves didn’t assume a job in the hormone recognition.
Hardware researcher Foone chose to discover what was inside a pregnancy test because of a tweet from a man addressing whether the computerized pregnancy test his wife had bought was worth the extra money.
According to BBC,
Digital pregnancy tests that display the words “pregnant” or “not pregnant” on a screen often cost about four times as much as ones that simply provide a single or double line on a paper strip to indicate pregnancy.For the experiment, Foone used a Walmart Equate digital pregnancy test.
The inner workings are similar to those in other brands including Procter and Gamble’s Clear Blue and the Boots own-brand digital pregnancy test.Foone was surprised to find the testing element inside was basically a standard paper test.Paper test strips detect a hormone called human chorionic gonadotropin, which is produced during pregnancy. The test strip is treated with a chemical that changes colour when the hormone is present.The electronics simply read the result from the paper test and then displayed the “pregnant” or “not pregnant” read-out.
The circuit board featured a “surprisingly complicated chip”, more powerful than the CPU used in the original IBM PC.Foone concluded that digital tests were “probably not worth the money”, given that paper strip tests can cost as little as 20 cents (15p).”It’s a scam, basically,” they wrote on Twitter. “Computers are cheap now. People are buying the digital one thinking it’s the more accurate fancy model, but it is the same.”However, others pointed out that paper tests could be misread and judging the result of the test was subjective.
“It is not stupid or wasteful to use a hardware interface to help women with this,” said tech YouTuber Naomi Wu.Assistant professor of bio-nanotechnology Vittorio Saggiomo agreed that interpreting the lines on a paper test could vary from person to person.
“I can see a faint line, another person doesn’t see anything,” he said.Another user added: “The information you are supposed to get out of it is literally life-altering. You don’t want to guess the outcome, or have to re-read the manual 10 times to know how to interpret a faint line.
I’d happily pay a few euros more.”Kate Bevan, a tech editor at consumer watchdog Which?, described it as a fascinating experiment but questioned whether the digital tests were creating unnecessary e-waste.Taking pregnancy tests apart appears to be a fairly frequent phenomenon on Twitter.
Also contained within the test is a moisture-absorbing tablet, to keep the circuitry dry before it is used.It has been incorrectly suggested on social media that this is an emergency contraceptive pill hidden inside the test.One video suggesting this has been viewed 4.5 million times on Twitter.In fact, the moisture-absorbing tablet is toxic and should not be eaten.
