Anyone ever have a false positive Gonorrhea Test?

So about a month back I took my 15 yr old step daughter to get tested for UTI and Yeast infection, they also went ahead and tested her for STD’s. I didn’t hear anything from the doctor about her results after that till just today when I received a letter telling me to call for her lab results. When I called they told me she tested positive for Gonorrhea but she swears up and down that she has never had sex. She’s been trying to think of any other possible way for it to have come back as positive since she says she’s still a virgin but I’ve never had a false positive on a STD test before or even heard of it. I take her tomorrow to get a shot to clear up the infection and plan to have them retest her before she gets the shot but has anyone ever dealt with something like this before and it come back as a false positive or even come back as a non sexual reason that they are testing positive?
