@molly0xfff this was what mine looked like (sorry i don't have another photo) that was delivering false results. if yours looks alike, you might repeat the test with no sample and see if it gives a false positive.
@molly0xfff did you get that tested with a home test or a hospital test? I did a home test a few months ago and it was positive, then I did it again, with just the ingredients and no sample at all and it was positive, too. I had always thought that the false positives were non-existent, but that is not the case.
