At age 30, how often you need a cervical screening (smear test) depends on your location and the specific guidelines being followed:
In the UK (NHS)
- England: Routine cervical screening intervals are every 5 years for individuals aged 25 to 49 who test negative for high-risk HPV (following changes implemented in July 2025).12
- Scotland, Wales, and Northern Ireland: Routine screening for individuals aged 25 to 49 is traditionally every 3 years, though policies vary or transition over time. Always check the specific interval stated on your latest NHS invitation letter.123
International Guidelines (e.g., US / ACOG / General Practice)
- Every 3 years if you have a Pap test (cytology) alone.
- Every 5 years if you have co-testing (Pap test combined with an HPV test) or high-risk HPV testing alone.123
Note: If you have had previous abnormal results, a weakened immune system, or symptoms like unusual bleeding, your doctor may recommend more frequent testing or a referral to a colposcopy clinic. 12You can find more details or check your eligibility through the NHS Cervical Screening Service.1To help give you more tailored information, are you registered with a GP in a specific part of the UK, or are you looking for guidelines from another country?
