This is sometimes my example for ‘why paying attention to documentation is important’. I didn’t take the photo myself, a colleague sent it to me years back.
Congratulations you’re having a Schrodinger’s baby
Ooh, this is a great idea. I could use a zener diode and a pregnancy test to make a test that reverses the result half the time, depending on electron-tunelling.
It’s both negative and invalid. Does that mean positive? Neutral? Indeed a conundrum.
Probably the top one is the correct one based on other test strips I have seen.
1 for control 1 for active and if control doesn’t show it’s a invalid test.
Yup that’s exactly what it is.
For pretty much every test like this. Pregnancy, ovulation, flu, Covid, you name it. One line is negative because the top line is the control because the control line reacted but the reactive line didn’t , two lines is positive because the control line reacted as well as the reactive line, and no lines (or no top line and a bottom line) is an invalid test because the control didn’t react at all.

Yes for sure! I think most people would conclude that as well, if they’ve used any form of control/test strip before.
Certainly Covid made us all familiar with that!
Congratulations, you’re pregnan’t!
lol this is so bad. Cheapies are sometimes terrible but man, these are especially awful.
Two lines is usually positive.
Negative, positive, or disabled? Just what the heck kinda pregnancy test is that…
If pregnant xor not pregnant return true
Husband goes to buy 12 liters of milk because they had eggs.
It’s invalid, not invalid. You have the emphasis on the wrong syllable. English is dumb.
