Cervical screening can be a surprisingly worrying appointment to book. Will it hurt? How long will you be undressed? What happens if you want the nurse to stop? Knowing the answers beforehand can make the visit easier. Cervical screening in the UK, still often called a smear test, is a routine preventive check for changes that could eventually lead to cervical cancer. The procedure is usually quick, and you remain in control throughout.
Who is invited, and how often?
Screening is generally offered to women and other people with a cervix aged 25 to 64. Eligible people often receive automatic invitations through their GP records. Trans men and non-binary people with a cervix may need to contact their practice to arrange screening, depending on how their sex is recorded.
The interval differs across the UK. England, Scotland and Wales generally offer routine screening every five years after a negative high-risk HPV result. England extended its five-year interval to eligible 25- to 49-year-olds in July 2025, although an earlier scheduled recall date may still apply. Northern Ireland currently invites people aged 25 to 49 every three years and those aged 50 to 64 every five years. Previous abnormal results can mean more frequent follow-up anywhere in the UK.
If you are over 64 and have never been screened, ask your GP for advice. People whose cervix was removed during a total hysterectomy usually do not need routine cervical screening, although individual follow-up can differ.
What does an NHS cervical screening test look for?
The laboratory checks a sample from your cervix for high-risk types of human papillomavirus (HPV). HPV is common, usually causes no symptoms and often clears naturally. If high-risk HPV is found, the same sample is checked for abnormal cervical cells. Identifying changes early allows monitoring or treatment before they potentially become cancer.
HPV screening in the UK is not a test that diagnoses cancer, nor does it test for every sexually transmitted infection. People who have received the HPV vaccine still need screening because the vaccine cannot prevent every HPV-related cervical cancer. Our guides to HPV vaccination and understanding HPV offer useful background.
Booking and preparing for the appointment
Most people book through their GP surgery, although some sexual health services provide screening. If you missed an invitation, contact the practice: you usually do not need to wait for another letter. The whole appointment commonly lasts around ten minutes.
Choose a day when you are not having a period. If your period starts on the day, call the surgery about rearranging. Mention unusual discharge or an infection that is being treated, as screening may be delayed until treatment finishes. You do not need to shave, wax or wash in any special way. Wearing a skirt or long top may help you feel covered.
If you are pregnant, speak to the surgery before booking. Routine screening is commonly postponed until after pregnancy, while follow-up after an abnormal result may be handled differently. You can also ask about a female clinician, accessibility adjustments or a longer appointment.
What happens during a smear test?
First, the nurse or doctor explains the cervical screening test and asks for your consent. You undress from the waist down in private and receive a covering sheet. You usually lie on an examination couch with your knees bent and apart, although alternative positions may be possible.
The clinician gently inserts a smooth instrument called a speculum into the vagina and opens it slightly to see the cervix. A soft brush collects a small sample of cells. The speculum is removed, and you can get dressed. The sampling usually takes less than five minutes.
For a first appointment, a useful request is: “Please explain each step before you do it, and stop if I raise my hand.” You can say this before undressing. It provides a clear signal and helps you remain involved throughout the procedure.
Ways to make screening more comfortable
Some people experience pressure or mild discomfort; others find screening painful, particularly with vaginal dryness, pelvic pain, vaginismus or past trauma. You can request a smaller speculum, ask to lie on your side, practise slow breathing or bring someone for support. Some clinicians may offer the option of inserting the speculum yourself.
You can pause or stop at any point, even after the examination has begun. If earlier tests were difficult, mention this when booking so the team can plan adjustments. You never have to continue simply because an appointment has started.
After the test: spotting and results
Most people return to everyday activities straight away. Light spotting sometimes occurs and normally stops within a few hours. Speak to your GP if bleeding is heavy or continues. The sample goes to a laboratory, and the clinician should explain when and how results will arrive. In England, they may appear in the NHS App or arrive by letter; arrangements differ elsewhere. Contact your surgery if results are overdue.
If high-risk HPV is not found, you usually return to routine screening. If HPV is found but there are no abnormal cells, another test is commonly arranged after 12 months. Persistent HPV can lead to further checks. If HPV and abnormal cells are both found, you are usually referred for colposcopy, a closer examination of the cervix. An HPV-positive result does not mean you have cancer, and HPV can remain unnoticed for years.
When symptoms need a GP appointment instead
Screening is designed for people without symptoms. See your GP if you have bleeding after sex, bleeding between periods or after menopause, unusual vaginal discharge or persistent pelvic pain. Do not wait for your next screening invitation. These symptoms can have several causes, but they deserve assessment. Our guide to unusual vaginal bleeding may help you prepare for that conversation.
Frequently asked questions
Does cervical screening hurt?
It can feel uncomfortable, and some people experience pain. Tell the clinician immediately, request adjustments or stop the test if you wish.
Can I have screening if I have never had sex?
You can discuss your circumstances with a GP or nurse. Risk is lower without sexual contact, but eligible people with a cervix are still invited.
Can I book after missing my smear test invitation?
Yes. Contact your GP surgery or a local service offering screening. You do not usually have to wait for another invitation.
Does a positive HPV result mean cancer?
No. It indicates a common virus was detected. Your result will explain whether any cell changes were found and what follow-up is needed.
A small appointment with a clear purpose
Knowing the procedure, understanding your local screening schedule and asking for any adjustments can make cervical screening less intimidating. Its purpose is to detect risk early, and you decide how the appointment proceeds.
