a pap test isn't a std test. it checks for abnormal cervical cells. you still still separate std testing to know your full status. if they didn't also get urine and blood testing, you didn't have full std testing done!

Usually they ask you because it costs more (although insurance usually covers). Swabs only test for HPV, gonorrhea, and chlamydia to my understanding. Herpes, syphilis, and HIV are all blood tests unless you have a lesion. If I were you, I would call your doctor; they should have on file what you were tested for, when, and the results. Pap smears and annual exams do not ensure that you've had STD testing.
