I have recently been tested for Chlamydia & gonorrhea after a low risk episode (no penetration, just frottage). When I got to the doctors i had not urinated for some time (2 hours), so i asked the doctor for a sample jar while i was waiting. I was under the impression that a mid stream sample was required and so thats what I produced. The doctor then told me that I infact needed a initial void sample, so I then produced that only 20 minutes after the first mid stream sample. the doctor indicated that he would use the initial sample to test for a UTI and the 2nd sample to Test for STD's. I am now concerned that the samples I provided were produced to close together and that the fact that the initial sample was a midstream sample may have also proved pointless. Please let me know if I can consider the negative results accurate as I have a small amount of discomfort at the tip of my penis, not when urinating but periodically through out the day 9this is the only symptom I have)
