Why does it take more than one pregnancy test to get 100% certainty? Why is one usually not trusted?
In: Biology
A huge part of the problem is that you unpack an indicator intended for one time use, that straight out of the package indicates NO. And after you’ve taken the test, and it still says NO, how can you be sure that it’s the correct answer?
Did you do the test correctly? Is it working correctly? (was it manufactured correctly?)
And at this point, we are only talking about if you get a false negative. If it incorrectly tells you that you are not pregnant.
In the next step, you have to address all the things that could give a false positive; the things that could suggest that you are pregnant even though you are not. This includes rare medical conditions that could fool the test. And again, manufacturing issues. And use that goes against the instructions.
