If the HPV test shows you do not have HPV, but your Pap looks abnormal, it is unlikely that you need to worry. The presence of a high-risk type of HPV is necessary for cancer to develop. However, just to be sure, the guidelines recommend that you get a colposcopy. If you do not have HPV but your Pap results are unclear or inconclusive both the HPV and Pap tests should be repeated in a year.
