Eli5 why do pregnancy testers not have a yes or no indication on the screen instead of the symbols and then matching them?

One reason would be so they can easily manufacture and sell the same test in multiple international markets without having to do any localisation.


That said, some do come with written-language results (at least in the UK a lot of the 'digital' ones will show 'pregnant' as a result).
