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.
Between 21 and 29, a Pap smear should be performed every three years. In this age group, HPV testing should only be used if a Pap smear returns with abnormal cell results. When a woman turns 30, the Pap smear should be used along with an HPV test. This co-testing should continue at five-year intervals until age 65.
