This sounds more like imaginary pregnancy test then real one. The real ones dont do faint line-ish. Also, for christ people, 16 years old were administrating these tests for years now, without there being massive social problem of confused woman. They just somehow managed to do them, even if their school results were very bad. So trying to claim they are somehow difficult to interpret is absurd.

Early on in the pregnancy the hormone levels are low and the line is faint. Obviously no one is saying a dark line is hard to interpret...

And the majority of those are inconclusive results which should be reported by digital as ... inconclusive. Removal of doubt here can cost you precious time.

The advantage is the UX. On a regular stripe test you are responsible to conduct the experiment and interpret the outcome which can be intimidating. "Is there a line? I think I see a line? But it's fainter from the last time? What does it mean?" This is replaced by an algorithm that's written by people who know what are they doing to save you from analysing a chemical reaction and have a straight answer. edit: Just G…

This is first time I hear about pregnancy test being "intimidating". The only pregnancy test intimidating reference I knew about so far was "omg, shit I am pregnant shit".

I don’t have enough close female friends to hear these worries from, but I’ve seen it as a trope in movies and TV shows many times where the woman tries to interpret the strip, gets it wrong, etc

Your link actually shows you why there is no UX advantage. OP is only two cycles into their pregnancy. A paper test can pick up on this tiny HCG measurement and show something. A digital test cannot because it's going to pick a higher threshold if it only wants to give you a binary result. A digital test will tell you that you're pregnant when you're far enough along for a paper test to be obvious. There are so many…

A digital test can be tuned to a better sensitivity.

The UX advantage comes from giving a definitive answer. The answer can change at later times when the body starts giving stronger signals. You can simply indicate that you need to wait X number of days to detect the pregnancy and problem solved.

This is much better UX than learning biology and chemistry to be able to read a test result. What does a faint line means? Probably means you need 4 years degree in a related field to have an educated guess. To have a definitive answer you need a to have a career in it.

Realistically though, it means you will need to ask someone who already have the degree, which means what good is the test for?

The digital test does guide you how to get to the right answer. Yes, if the threshold is too high and you test too early it can give you a false negative but this is a simple problem that can be solved by recommending a second test in few days.

People often have the idea that a digital readout implies a more precise measurement. I see this often in scales, thermometers, etc.

It is often more precise, not necessarily more accurate. People often don't distinguish between the two.

Not a native speaker; I think I understand your point, though I fail to see a distinction between these two words: if the output is a number to the nth decimal, but it is not "accurate" (ie. the numbers are actually wrong), can it still be said to be "precise" ?

Precise means lots of fine-grained information; accurate means close to the truth. If the weather is 20° exactly and one thermometer reads 20.2° and another 20.562° the first can be described as more accurate and the latter as more precise. Hence the expression, “precisely wrong”.

I wonder if there is an opportunity to make a mobile app that interpreted the results from these tests in a similar manner and sell tests that are app enabled.

Had the same idea just before seeing your comment as I pondered over another discussing the horrendous environmental cost.

It's surprising because the electronics are essentially useless. Most people would expect the electronic version would have some type of advantage, because those electronics cost extra money to produce.

> The advantage is the UX.

The UX in this case is bad. Unnecessary and expensive fluff that obfuscates reality and gives a false sense of certainty to the user.

> On a regular stripe test you are responsible to conduct the experiment and interpret the outcome

The part of conducting the experiment is identical, I think, regardless of the type of test. You pee on it. Interpreting the results is not an issue. You simply need to observe with your eyes (a product of billions of years of evolution) if you have || or |+.

> save you from analysing a chemical reaction and have a straight answer

Again, you don't need to analyze a chemical reaction any more than the device does. The conclusion of the analysis is summed up in [1]. The whole point of the digital part is to read the lines on the paper. Whatever heuristics went into deciding how much reflected light should be interpreted as a | or a + are just as likely to be mistaken as a human eye reading would be.

But this link shows exactly why plain chemical tests are superior, no? The poster's question was about the conflict, not the interpretation of the chemical test. >FRERs can pick up hCG as low as 7. Digitals require >40. Try with a digital in another week! This seems to me like you're replacing an analogue, more precise reading with a binary, easier to read, imprecise reading?

Superior sensitivity != Superior UX.

Yeah, sure if you know what you are doing observing chemical reaction can be much better. It's like the difference between consumer tools and industrial tools.

Full manual espresso machines are superior from the perspective of a coffee nerd or professional. Nespresso machines with capsules are superior from the perspective of the person who wants the coffee but doesn't fancy learning making one.

Reminds me of that juicer which basically just squeezed a packet and costs hundreds of dollars. Thank god for hackers exposing these shenanigans!

And it was selling at a loss as well; the device was ridiculously overbuilt, see this teardown by everyone's favorite canadian dad: https://www.youtube.com/watch?v=_Cp-BGQfpHQ
