Screening
Cervical Screening (Smear Test)
Cervical screening is a test that checks the health of the cervix. It looks for a virus (HPV) that can cause cell changes, helping prevent cervical cancer before it develops.
Quick answer
Cervical Screening (Smear Test): what it is and what the results mean
Cervical screening takes a small sample of cells from the cervix (neck of the womb). The sample is tested for high-risk types of human papillomavirus (HPV) and, if found, for cell changes, so problems can be treated early.
- Why it is done: It is offered routinely to prevent cervical cancer by finding and treating changes before they become cancer, rather than waiting for symptoms.
- Understanding results: If no high-risk HPV is found, the risk is very low and you are recalled at the usual interval.
What it is
Cervical screening takes a small sample of cells from the cervix (neck of the womb). The sample is tested for high-risk types of human papillomavirus (HPV) and, if found, for cell changes, so problems can be treated early.
Why it is done
It is offered routinely to prevent cervical cancer by finding and treating changes before they become cancer, rather than waiting for symptoms. It is one of the most effective cancer-prevention programmes.
What to expect
A nurse or doctor gently opens the vagina with a speculum and uses a soft brush to take a sample from the cervix. It takes a few minutes and may feel uncomfortable but should not be painful.
Understanding the results
If no high-risk HPV is found, the risk is very low and you are recalled at the usual interval. If HPV is found, the sample is checked for cell changes, which may lead to a closer look (colposcopy) or earlier repeat screening.
Good to know
Risks and limitations
The test is very safe; some people have light spotting afterwards. No screening test is perfect, so it is repeated at intervals, and you should still report any unusual symptoms between tests.

Answers
Cervical Screening (Smear Test): frequently asked questions
Does a smear test hurt?
Most people find it uncomfortable rather than painful. Telling the nurse if you feel anxious or sore, and trying to relax, can help. It only takes a few minutes.
What does an HPV-positive result mean?
It means a high-risk type of HPV was found, which is common and often clears on its own. The sample is then checked for cell changes, and you may be offered a closer examination or earlier repeat screening.
