Pap tests are not always 100 percent correct. False positive and false negative results can happen. This can be upsetting and confusing. A false positive Pap test is when a woman is told she has abnormal cervical cells, but the cells are really normal. If your doctor says your Pap results were a false positive, there is no problem.
A false negative Pap test is when a woman is told her cells are normal, but in fact, there is a problem with the cervical cells that was missed. False negatives delay the discovery and treatment of unhealthy cells of the cervix. But, having regular Pap tests boosts your chances of finding any problems. If abnormal cells are missed at one time, they will probably be found on your next Pap test.
