## TL;DR

Women who never book a smear test are missed by invitation-based screening. Posting an HPV self-sampling kit as the default invitation, as the Netherlands and Australia do, reaches them, and PCR-based self-samples match clinician samples for detecting high-grade precancer.

## Summary

HPV self-sampling has equivalent sensitivity to clinician-collected samples for CIN2+ with PCR-based tests. Propose opt-out mailed kits as the default invitation for all eligible women, with clinician sampling as an alternative, and triage of positives by extended genotyping or methylation to avoid unnecessary colposcopy.

## Fields

- Kind: Idea
- Last checked: 2026-09-08
- Hypothesis: Mailed default self-sampling raises screening coverage by at least 10 percentage points overall and 15 points in the most deprived quintile.
- Rationale: Dutch, Australian and Swedish experience; removes clinic access barriers and embarrassment.
- Proposed test: Switch the national programme with a stepped-wedge evaluation.
- Maturity: being-tested-at-scale
- Actor: policy
