Cervical screening

Cervical Screening
Who’s eligible
Anyone with a cervix aged 25–74 who has ever had any sexual contact (intercourse, oral sex, intimate skin-on-skin contact, anal sex) — regardless of HPV vaccination status, current sexual activity, relationship structure, or condom use (HPV spreads via skin contact a condom doesn’t cover). Screen every 5 years if HPV-negative.
That includes trans men and non-binary people with a cervix, who are often missed. Self-collection, the smallest speculum or self-insertion can make the test easier. See Gender Dysphoria.
The test
Primary HPV test with partial genotyping (HPV 16/18 vs other oncogenic types), either:
- Self-collected vaginal swab — now a fully equal, universally available option for anyone eligible (except when a co-test is specifically indicated, see below); or
- Clinician-collected cervical sample — allows reflex liquid-based cytology (LBC) on the same sample if HPV is detected.
Self-collection is exactly as accurate as clinician-collection for detecting HPV and CIN2+. If HPV is detected on a self-collected sample and cytology is needed, the patient returns for a clinician-collected LBC sample (as soon as practical, ideally within 6 weeks) — or, if going straight to colposcopy, the LBC sample is taken there instead, without a separate visit.
Who needs a co-test instead (not eligible for self-collection)
- Symptoms suggestive of cervical cancer: unexplained postcoital bleeding, persistent intermenstrual or postmenopausal bleeding, unexplained persistent unusual vaginal discharge, or an abnormal-looking cervix
- Treated for adenocarcinoma in situ (AIS)
- DES exposure in utero
Co-testing/colposcopy referral is not needed for bleeding clearly attributable to hormonal contraception, sample-collection contact, heavy-but-regular periods, or an STI.
Results pathway
| Result | Action |
|---|---|
| HPV not detected | Routine 5-yearly screening |
| HPV 16/18 detected | Direct colposcopy referral regardless of LBC result |
| HPV (not 16/18), LBC negative/pLSIL/LSIL | Follow-up HPV test at 12 months |
| HPV (not 16/18), LBC pHSIL/HSIL/glandular abnormality | Colposcopy referral |
| Unsatisfactory HPV | Repeat ASAP, ideally within 6 weeks |
At the 12-month follow-up: HPV not detected → return to routine screening. HPV 16/18 → colposcopy. HPV (not 16/18) → repeat LBC; if still negative/LSIL, a further follow-up HPV test at 24 months; if that’s also HPV-negative, return to routine screening — if HPV is still detected at 24 months, colposcopy regardless of type.
Direct-to-colposcopy exception at the 12-month follow-up (skip the repeat-LBC step, go straight to colposcopy if HPV any type is detected, regardless of LBC result) applies if the patient:
- Was overdue for screening by ≥2 years at the time of the original positive test, or
- Identifies as Aboriginal and/or Torres Strait Islander, or
- Is aged ≥50
Special groups
Immune-deficient (HIV, solid organ transplant, congenital immune deficiency, immunosuppressant therapy for autoimmune disease, GVHD post-BMT): 3-yearly screening; any oncogenic HPV type detected → direct colposcopy referral.
DES-exposed in utero: annual co-test + colposcopic exam of cervix/vagina, indefinitely.
Pregnant: screen at any stage of antenatal care if due/overdue — spotting after the procedure is expected, harmless, and self-limiting. Use a broom-type brush, not an endocervical brush/cytobrush (bleeding risk). Self-collection is fine at any point in pregnancy — check the swab is validated for use in pregnancy with your lab. Can defer to the postnatal visit if preferred.
Vaginal/cervical atrophy: if a previous smear was atrophic, or the patient has postmenopausal vaginal atrophy, consider 2 weeks of vaginal oestrogen first — stop 2 nights before the test.
Aged 70–74 (exit test) or ≥75 requesting screening (never screened, or none in the last 5 years): HPV not detected → exit the program; any HPV type detected → direct colposcopy referral regardless of LBC result.
After hysterectomy
| Scenario | Follow-up |
|---|---|
| Subtotal (cervix remains) | 5-yearly HPV test as usual |
| Total, normal prior screening, no pathology at hysterectomy | No further surveillance |
| Total, treated for histologically-confirmed HSIL with completed Test of Cure, no pathology at hysterectomy | No further surveillance |
| Total, HSIL found at hysterectomy / incomplete Test of Cure / unknown or never screened | Annual HPV test (vaginal vault) from 12 months post-op, until 2 consecutive negatives → then stop |
| Total, AIS history | Annual co-test (vaginal vault) from 12 months post-op, until 2 consecutive negatives → then stop |
Test of Cure after HSIL (CIN2/3) treatment — changed 2025
Now HPV-only testing (not co-testing), starting 12 months post-treatment: annual HPV tests until 2 consecutive HPV-not-detected results, then return to routine 5-yearly screening. Co-testing is reserved for a case-by-case decision only where excision margins were positive. (Patients partway through the old co-test-based pathway before 1 July 2024 can complete it via a second 12-month HPV-only test.)
AIS surveillance after treatment — changed 2025
No longer indefinite annual co-testing. Now: annual co-testing for 5 years; if all negative, extend to 3-yearly; after 25 years of negative surveillance, patients <70 return to routine screening, and patients ≥70 can exit entirely (provided at least one co-test since turning 70 was HPV-negative and LBC-negative).
Practical notes
- Avoid carbomer-containing lubricant (excessive amounts can interfere with testing); carbomer-free options include medical-grade KY Jelly, Surgigel, Astroglide.
- STI screening (chlamydia, gonorrhoea, trichomonas, M. genitalium) can be co-collected in the same liquid-based medium if indicated by risk.
- The NCSR no longer honours “not for register” instructions on pathology forms — patients who want to opt out must do so via the NCSR Participant Portal or Healthcare Provider Portal, not by a form annotation.
