when I went into the ER the other day for pain, they did a pelvic exam and urine. all that fun stuff. well I got the bill today and it had on there that they did a gonorrhea and chlymida test.. well before I left the hospital I was told that everything looked good. did they get the std tests back that night too ?? I had no idea they were even checking for that
