I took an NAAT test for Chlamydia and Gonorreah in early July five months after a possible exposure and it came back negative for both. When I provided the sample I did shortly after starting urination. That is, it wasn't first catch, it was shortly after. Does this impact testing results? From what I have read and I also in talking to the county STD clinic, the way testing is now whether it's mid-stream or first catch does not make a difference. I don't have any symptoms and it's been six months now. I guess I am just worried about a false negative for some reason. Any help answering this is appreciated.
