You and your doctor can decide when it's time for you to begin Pap testing and how often you should have the test. In general, doctors recommend beginning Pap testing at age 21.
In the United States, Pap smear screening is recommended starting around 21 years of age until the age of 65. Guidelines on frequency vary from every three to five years. If results are abnormal, and depending on the nature of the abnormality, the test may need to be repeated in six to twelve months. Pap smear is performed by opening the vaginal canal with a speculum, then collecting cells at the outer opening of the cervix at the transformation zone (where the outer squamous cervical cells meet the inner glandular endocervical cells).
