I recently was told by a partner that I gave him gonnorrhea, I get tested regularly so I thought that it wasn't possible. I went in yesterday for a full STI/STD check up. Now I'm concerned as to whether the lab would be able to detect rectal gonnorrhea if they only took a vaginal swab as a sample? I hadn't realized that the gonnorrhea could've been transmitted during anal sex. Is it possible to have had undetected rectal gonnorrhea dispire being tested regularly. The samples have always been blood, urine, and vaginal swabs?
