On A Girl's Last Visit To Her Pediatrician

I have heard from several female friends that on their last visit to the pediatrician, they received a more extensive and thorough examination. Most of whom would have been going off to college in the fall, they claim that they were afforded less modesty and their private areas were examined more closely. For example, one friend who's doctor would normally only lift the waistband of her underwear, removed her panties completely and performed a genital exam. Another claimed that she would normally only strip to her bra and panties, but this last time she was ordered naked under a gown. Is it common for a pediatrician to make his last exam of a patient more thorough? Ladies, what were your personal experiences the last time you were examined by your pediatrician?

A lot of teenagers don't visit the doctor for regular checkups unless they have to. So, it's possible for a girl (or a boy, for that matter) to have a physical when entering high school (or even middle school) when it's required, and then not again until it's time to go off to college. So, what seems like a "final" more detailed exam could actually be what what would have been done at every visit throughout high school had he or she gone in for an appointment every year.
