It would find the abnormal cells from .H.P.V and if untreated the cells of the cervix will change also with clymidia.(sp)
but first they find the abnormal cells then test to see what those cells are from. This is how my daughter found she had .H.P.V. She has never had a wart from hers. And it can also tell them if the .H.P.V is inactive when they do the pap smear.
But there are many other std's that have to be cultured, and or blood drawn for them.
You need to get yourself checked periodically---especially if you have many partners, engage in any high risk situations, if you use or share needles, or have sex with anyone who does, and if you have sex without condoms, or you find your partner has not been "truly faithful" to you. And if you cannot answer any of these questions with a definative no, get checked again.
Make sure you are safe. They even have meds now to halt the progression of the hiv virus. So knowing is much better than the alternative--right?
