A smear test may detect abnormal (precancerous) cells of the cervix. Also known as cervical screening, it help to identify changes in the cervix at a very early stage before any significant complications arise.
If you have undergone a smear test, there are three possible results: Normal, Unsatisfactory and Abnormal.
An abnormal smear test suggests changes that might potentially result in cervical cancer in the future.
In fact, a wart virus known as the human papillomavirus, or HPV, causes most smear abnormalities.
