What does a pap smear test for?
A pap smear tests for changes in the cells of the cervix. Cells from the cervix are collected so that they can be examined for any changes – changes in cells can indicate the possibility of their developing cancer. A pap smear also tests for HPV, which stands for human papilloma virus. This is a very common virus in humans which can cause genital warts. The reason this virus is tested for is because the warts associated to it can cause changes in the cervical cells which can later develop into cancer.
