A Pap test examines cells scraped from the cervix for abnormal changes that could indicate cancer. The American College of Obstetricians and Gynecologists recommends that women have a yearly Pap test. An annual test is especially important if you are at higher than average risk for cervical cancer. You are at higher risk if you became sexually active before the age of 18, have multiple sex partners, have a history of pelvic infections, have ever had an abnormal Pap smear, have a history of precancerous changes of the cervix, or if your mother took diethylstilbestrol (DES) when she was pregnant with you.

To help ensure accurate results, avoid douching, using vaginal medications, or having sexual intercourse for 24 hours before the test.
