You won't have to worry about them knowing what to do since the test is done on the same pap smear (brush cytology) that they are already taking. While this is usually done on the cervix, my understanding is that they still collect cells from the surrounding area if you have had surgery. Given all the publicity that this is getting with the TV ad campaign about HPV ( they haven't even gotten into the issue of the vaccine on TV ads yet since the American public is so uniformed about HPV that they are going with 5 million in just HPV ads alone first) and lots of women are finally coming in asking about getting tested. When my wife had it done it was $50.00 extra for the test... but get this - the gyn tryed to talk her out of it, saying it wasn't necessary. 'Course that was before the vaccine was out there two years ago.
