Getting both the digene HPV Test and a Pap offers the most peace of mind for women 30 and older -- the age group that is most at risk of cervical cancer. If you do not have HPV and your Pap is normal, you can be confident you do not have abnormal cells that could develop into cervical cancer without being detected.
If your PAP test is normal, but your high-risk HPV test is positive, do not panic. Nothing further needs to be done. What's recommended is that you have another PAP test and high-risk HPV test in 6 to 12 months time. If your PAP test is abnormal, and your high-risk HPV test is positive, we recommend colposcopy, which is a further evaluation of the cervix under a microscope. If your PAP test is abnormal and your high risk HPV test is negative, we still recommend colposcopy, because remember we are treating the abnormal cells on the cervix that HPV can cause.
