After few months of my high risk exposure, I did a real time pcr urine test for (Chlamydia-RNA , gonorrhoeae-DNA , Trichomonas-RNA , mycoplasma-RNA) all came back negative and no symptoms until now. But it is not my first void urine but I did hold my urine for 1 to 2 hours. Do I need to retest or I can get over it
