HPV screening for cervical cancer, HPV-primary testing with reflex cytology — the NHS since 2019.
HPV-primary cervical screening — offered by the NHS since 2019 — tests a cervical liquid-based sample for high-risk HPV first, with reflex cytology only if HPV is positive. More sensitive than cytology alone; extends the screening interval to every 5 years for women aged 50–64.
Key facts at a glance
- 01
Definition
HPV-primary cervical screening with reflex cytology — the sample is tested first for high-risk HPV, and cytology is only performed if HPV is detected.
- 02
NHS offers women 25–64
The NHS Cervical Screening Programme invites all women and people with a cervix aged 25–64.
- 03
Interval 3 or 5 years
Every 3 years from age 25–49, and every 5 years from age 50–64 — reflecting HPV testing’s higher sensitivity.
- 04
More sensitive than cytology
Higher sensitivity than cytology alone for detecting high-grade CIN and early cervical cancer.
- 05
Self-sampling under evaluation
Vaginal self-sampling for HPV is being evaluated as a way to widen participation for under-screened groups.
- 06
Complements HPV vaccination
Screening remains essential even for HPV-vaccinated cohorts — the two strategies work together to eliminate cervical cancer.

- 01
Before
Book with GP or private clinic
Arrange your appointment through your NHS GP practice or a private women’s health clinic.
- 02
Before
Avoid intercourse and lubricants for 24 hours
These can interfere with the cellular sample. Also avoid vaginal creams and pessaries in the 24 hours before your test.
- 03
Before
Attend day 10–14 of cycle if possible
Mid-cycle timing gives the cleanest sample. Not essential — but useful if you can plan it.
- 04
On the day
Speculum and cervical sample with brush
A gentle speculum examination, then a soft brush sweeps cells from the cervix into a liquid-based cytology vial. Two to three minutes.
- 05
On the day
Sample tested for high-risk HPV first
The lab tests the vial for high-risk HPV genotypes — the front-line test in the NHS pathway since 2019.
- 06
On the day
Reflex cytology if HPV positive
If high-risk HPV is detected, the same sample is examined under the microscope for cellular abnormalities.
- 07
After
Written result in 2–4 weeks
Result letter arrives in 2–4 weeks with the next step: routine recall, 12-month repeat, or colposcopy referral.
Typical result letter: 2–4 weeks. Reading time for this guide: 6 minutes.
What it shows
What an HPV-primary result actually tells you.
Each possible result has a defined pathway — from routine recall to urgent colposcopy.
-
HPV-negative (very low risk)
A negative high-risk HPV result carries a very low short-term risk of cervical cancer — routine recall interval applies.
-
HPV 16 / 18 (highest cancer risk)
HPV genotypes 16 and 18 cause around 70% of cervical cancers — a positive result triggers direct colposcopy referral in most pathways.
-
Other high-risk HPV genotypes
The other twelve high-risk genotypes carry a lower but still meaningful risk — reflex cytology decides the next step.
-
Reflex cytology normal (HPV persistence follow-up)
HPV-positive with normal cytology means a 12-month repeat — most HPV infections clear on their own.
-
Reflex cytology abnormal (colposcopy)
Any grade of dyskaryosis on reflex cytology triggers a colposcopy appointment for direct cervical inspection.
-
Post-treatment HPV clearance monitoring
After LLETZ or cone biopsy, an HPV-negative test of cure is the strongest reassurance of successful treatment.
-
Post-menopausal HPV monitoring
Persistent HPV after the menopause deserves careful assessment — hormonal atrophy can complicate cytology interpretation.
-
Red flag: HSIL / SCC on cytology or persistent HPV — colposcopy pathway
High-grade squamous intraepithelial lesion, invasive features, or persistent HPV need urgent colposcopy — not a repeat smear.
Next steps
The full range of onward pathways.
From a straightforward 12-month repeat to fertility-sparing surgery — the eight onward routes after HPV screening.
-
Repeat in 12 months if HPV+ / cytology normal
Most transient HPV infections clear inside a year — a repeat test at 12 months is the standard follow-up.
-
Colposcopy for abnormal cytology
Direct visualisation of the cervix with a colposcope, with acetic acid and iodine staining to localise abnormal areas.
-
LLETZ for confirmed high-grade CIN
Large loop excision of the transformation zone — the definitive outpatient treatment for CIN2 and CIN3.
-
Trachelectomy / hysterectomy for cancer
For confirmed invasive disease, fertility-sparing trachelectomy or hysterectomy according to stage and patient priorities.
-
HPV vaccination if unvaccinated
Catch-up vaccination remains valuable — nonavalent vaccine covers the nine most oncogenic HPV genotypes.
-
Cascade family and partner discussion
HPV is common and sexually transmitted — an open conversation with partners and adult family members supports informed screening choices.
-
Structured follow-up per BSCCP
Colposcopy and treatment follow-up follows British Society for Colposcopy and Cervical Pathology standards.
-
Multi-disciplinary team review
Invasive or complex cases go to a gynae-oncology MDT — gynaecologist, oncologist, radiologist, pathologist and specialist nurse.

Red flags
When routine screening isn’t enough.
Any of these features means the screening pathway shifts to urgent colposcopy or a two-week-wait gynae-oncology referral.
-
HSIL cytology
High-grade squamous intraepithelial lesion — direct colposcopy referral, not a repeat smear.
-
Invasive cervical cancer
Cytology features suggesting invasion — urgent two-week-wait gynae-oncology pathway.
-
Glandular abnormality
Atypical glandular cells warrant urgent colposcopy and endocervical assessment.
-
Persistent HPV 16 / 18
Two consecutive HPV 16/18-positive results warrant colposcopy even with normal cytology.
-
Post-menopausal bleeding
Any bleeding after the menopause is a red flag — go straight to your GP for a two-week-wait referral.
-
Post-coital bleeding
Bleeding after intercourse warrants direct cervical inspection — don’t wait for the next screening round.
-
HIV + high-grade CIN
Immunosuppression accelerates HPV progression — more intensive surveillance is required.
-
Recurrent HPV in immunocompromised
Transplant recipients and others on immunosuppression need a tailored, more frequent screening schedule.
-
Failed test of cure post-LLETZ
A positive HPV test after treatment triggers repeat colposcopy — persistence, not recurrence, is the concern.
Reading your result
An HPV-primary result letter can look technical. It isn’t.
Whatever the finding, the report keeps to the same four parts.
A quiet reminder
Most HPV-positive results clear on their own within a year.
An HPV-positive result is common and does not mean cancer — it means a closer look is worth doing.

Frequently asked
Everything we get asked about HPV cervical screening.
Quick answers on the NHS pathway, HPV-positive results, vaccination, self-sampling and what to do if a symptom appears between screens.
-
What’s the difference between the old smear test and the new HPV screening?
The old smear looked at cell changes first; HPV-primary screening tests the same liquid-based sample for high-risk HPV first, and only runs cytology (reflex) if the virus is detected — a more sensitive way to catch pre-cancer earlier. The NHS moved to this pathway in 2019, and privately in London you can have it any time from about £180–£280 with results in a week rather than waiting on your NHS recall.
-
Who is offered HPV cervical screening on the NHS?
All women and people with a cervix aged 25–64 in England. Invitations are sent every three years from 25 to 49, and every five years from 50 to 64. The extended interval for older women reflects the higher sensitivity of HPV testing.
-
Is HPV screening better than a traditional smear?
HPV-primary screening is more sensitive than cytology alone — it detects more high-grade CIN and reduces cervical cancer incidence and mortality. That is why the NHS, and most European programmes, have moved to this pathway.
-
What happens if I test positive for HPV?
Reflex cytology is performed on the same sample. If cytology is normal, you are invited back in 12 months to check whether the HPV has cleared. If cytology is abnormal, or if HPV persists, you are referred to colposcopy.
-
Do I still need screening if I have had the HPV vaccine?
Yes. The HPV vaccine protects against most — but not all — high-risk HPV genotypes, and does not treat existing infection. Screening remains essential even for fully vaccinated cohorts.
-
Is HPV self-sampling available?
Vaginal self-sampling for HPV is under evaluation in the UK as a way to reach under-screened groups. It is not yet the routine NHS offer, but is likely to become available in the coming years.

In practice, in London
What HPV screening for cervical cancer looks like on the ground in London
With HPV screening for cervical cancer, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. The NHS route for HPV screening for cervical cancer is thorough, but the queue is real. Most patients we speak with have been told to expect anywhere from a handful of weeks to several months, depending on their local trust and how the referral is graded. Going private in London usually collapses that window to a matter of days — often the same week if the diary allows. It isn’t about jumping a queue so much as buying time back while you still have the flexibility to plan around it.
In practice, a private HPV screening for cervical cancer appointment in London means a named consultant, a proper hour in the room (or the equivalent on a video call), and a report you can actually read. Most of the imaging suites and endoscopy units we use sit within a mile of Harley Street or in Chelsea and Fulham, and turnaround on findings is measured in days, not weeks. For HPV screening for cervical cancer specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
Where a good concierge earns its keep is in the matching. There are dozens of consultants in London who see HPV screening for cervical cancer — but not all of them are the right fit for every case. We narrow it down based on subspecialty, insurer coverage, the specific question being asked, and whether continuity into treatment matters. The right first appointment saves you from repeating yourself later.
