if you do not have active lesions at the time of your test (not sure what kind of std tests you had. not all of them even check for herpes) it could have been a false negative test. if you are continuing to have unprotected sex you could have picked up herpes 2 anytime. there are no laboratory tests that will prove when you got it.
can herpes 2 go unnoticed on an std test? . a year ago i had blood urinary and swab test only to find out i had herpes 1 and a yeast infection/ uti. i am a male so it was all new to me. after about a year or so i had developed sores under the head of my penis so i went and got a urine/blood test done and was informed that i have herpes 2. so i am wondering if i could have had it this whole time and it didn't show up before since there were no signs? or if i did in fact recently receive the virus?
