I have literally no idea how the test works; I'm a software engineer. They're supposed to be similar to pregnancy tests right? But those detect hormones afaik,

  The test contains antibodies for the virus, so if they react in any way (assuming you weren't tampering with it[1]) then you have the virus. Those tests are considered unreliable, because the false negative is high (i.e. not enough of the virus to register). I don't know enough about pregnancy test, but I assume the hormone is always present, it's just certain level of it signals pregnancy. [1] there were videos where people where testing juices and soft drinks and that was messing up the test.
