Guidelines for Pap smears vary, but generally, it is recommended for women to start getting Pap smears at age 21 and continue every three years until age 29. From age 30 to 65, women should have a Pap smear combined with an HPV test every five years or a Pap smear alone every three years. After age 65, women with a history of normal Pap results may be able to stop testing.
