I gave a urine sample and tested negative for chlamydia, gonorrhea, and trich. My symptoms seem closest to trich symptoms. I was given an antibiotic for chlamydia, which made the symptoms go away, but they came back shortly after finishing the medicine. I tested for GC and Chlamydia twice and both were negative, so I don't think that's a concern. How common is it for a man to get a false negative trich result?
