A “smear test” usually means a cervical screening (Pap smear or HPV test), and how often you need one depends mainly on your age, where you live, and your previous results.

Typical screening intervals

• Many guidelines recommend:
  • Ages 21–29: Pap smear every 3 years if results are normal.

* Ages 30–65: either a Pap test every 3 years or a combined Pap + HPV (co-test) every 5 years when results are normal.

* Over 65: often no further tests are needed if you have had a series of normal results and no history of cervical cancer or serious cell changes, but this is individualised.

Country program examples

• UK/parts of Europe: invitations typically every 3–5 years between about ages 25–64, with longer (5‑year) intervals when HPV-based screening is used and results are negative.

• Australia and some other countries using primary HPV testing: cervical screening test every 5 years for people with a cervix in the target age range, if results are normal.

When you may need it more often

You may be advised to screen more frequently or continue past 65 if you have had abnormal smear results, HPV-positive tests, a weakened immune system, a history of cervical cancer or high-grade cell changes, or certain types of treatment to the cervix.

Because schedules differ by country and personal risk, the safest step is to ask your GP or gynecologist what interval applies to you, mentioning your age, country, and any past abnormal results.
