So I had no reason to take an overall STD test since I haven't had sex with anyone other than my ex-girlfriend of 3 years. I did make out with 2 people a few months after we broke p but that was it. I had some anxiety and germophobia one day and decided to go get a test for everything just for my own well being. I drove to the testing clinic knowing full well I was negative. But today I am getting my results and am having horrible anxiety about the DNA PcR test. I heard there are alot of false positives with that test and keep thinking "what-if" it's positive...my life is over. I am only 21 and if that test comes up positive my life will be ruined. I know it should be negative, but what are the chances it produces a false positive?
