self-sampling is a cervical cancer screening method in which a person collects their own vaginal specimen, usually with a swab or brush, and the specimen is tested for high-risk human papillomavirus (hrHPV) DNA. Its purpose is to raise screening participation among people who decline or cannot access clinician-collected sampling, because [HPV testing](https://www.edgepedia.org/hpv-testing) of a vaginal sample detects cervical infection almost as reliably as a clinician-taken cervical sample when a PCR-based assay is used.[1](https://www.mdpi.com/2072-6694/12/4/1053) WHO positions self-sampling as an additional option to improve screening coverage where HPV tests are available in the national program, in support of the global target of 70% screening coverage by 2030.[2](https://www.who.int/publications/i/item/WHO-SRH-23.1)\n\n| Fact | Detail |\n|---|---|\n| What it produces | A self-collected vaginal swab or brush specimen tested for hrHPV DNA (14 high-risk types on most assays)[1](https://www.mdpi.com/2072-6694/12/4/1053) |\n| Accuracy (PCR assays) | Pooled sensitivity 96% and specificity 79% for CIN2+ on self samples, not significantly different from clinician samples[3](https://www.ncbi.nlm.nih.gov/books/NBK545378/) |\n| Accuracy (signal amplification) | Sensitivity 77% on self samples vs 93% on clinician samples for CIN2+; specificity 84% vs 86%[4](https://www.bmj.com/content/363/bmj.k4823) |\n| Participation effect | Self-sampling roughly doubled screening uptake versus control (RR 1.8, 95% CI 1.7–2.0, across 154 studies)[5](https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2022.1003461/full) |\n| Invalid samples | On average 0.7% of self samples unsatisfactory for hrHPV testing (range 0.0–2.7%)[4](https://www.bmj.com/content/363/bmj.k4823) |\n| National programs | Netherlands (January 2017), Australia (December 2017, universal July 2022)[6](https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667%2825%2900304-4/fulltext) • [7](https://www.health.gov.au/sites/default/files/2025-11/final-report-for-the-self-collection-vs-practitioner-collection-project-2-scope2.pdf) |\n| US regulatory status | FDA approved office-based self-collection for cobas and Onclarity in May 2024 and later the at-home Teal Wand[8](https://www.ovid.com/journals/cajc/fulltext/10.3322/caac.70041~self-collected-vaginal-specimens-for-human-papillomavirus) |\n\n## How it works\n\nThe biological rationale is that HPV-based testing does not require sampling from the cervical transformation zone, because viral nucleic acid is shed from the cervix into the vaginal canal.[1](https://www.mdpi.com/2072-6694/12/4/1053) A swab rotated in the vagina therefore picks up enough virally infected cells to give the same answer as a cytobrush on the cervix, provided the assay is sensitive enough. The published concordance data support this: in an early evaluation of 268 women using Dacron swabs and L1 consensus PCR, overall agreement between clinician- and self-collected swabs was 88.1% (kappa = 0.73), with type-specific agreement higher for high-risk genotypes (kappa = 0.78) than for low-risk types (kappa = 0.66).[9](https://pubmed.ncbi.nlm.nih.gov/11219778/)\n\nThe mechanism has a practical corollary: because the cervix is not sampled directly, most individuals screening positive on a self-collected HPV test require guideline-directed follow-up, which may include clinician-collected cervical testing or colposcopy depending on the HPV type and applicable guidelines, rather than universal confirmation with a speculum examination before treatment decisions are made.[10](https://www.asccp.org/wp-content/uploads/2026/01/ASCCP-Practice-Advisory-Self-Collection-for-Cervical-Cancer-Screening-updated_10-2-25.pdf) • [23](https://pmc.ncbi.nlm.nih.gov/articles/PMC11939108/)\n\n## How it is done\n\nIn the Australian National Cervical Screening Program, the participant twists the cap off the tube, inserts the swab a few centimeters into the vagina to a red line marker (the cervix does not need to be reached), rotates the swab gently for 10–30 seconds, and returns it to the tube.[11](https://www.health.gov.au/sites/default/files/2025-09/national-cervical-screening-program-frequently-asked-questions-about-the-cervical-screening-test-self-collect-option.pdf) BC Cancer's instructions specify rotating the swab while slowly counting to 20, and explicitly warn not to use the vaginal swab to sample the cervix.[12](https://www.bccancer.bc.ca/screening/Documents/Cervix-Self-Screening-Clinic-Instructions.pdf) Patients should not be on menses at the time of collection, nor have used vaginal products for 48 hours beforehand.[10](https://www.asccp.org/wp-content/uploads/2026/01/ASCCP-Practice-Advisory-Self-Collection-for-Cervical-Cancer-Screening-updated_10-2-25.pdf)\n\nSpecimens can be transported dry or in liquid medium, and each combination of device, buffer, and assay requires its own validation.[1](https://www.mdpi.com/2072-6694/12/4/1053) In Australia, self-collection uses a Copan FLOQSwab with either manufacturer-validated (Roche, resuspension in ThinPrep) or laboratory-validated dry-transport methods eluted in PreservCyt or MSwab media.[6](https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667%2825%2900304-4/fulltext) [Assay](https://www.edgepedia.org/assay) validation runs through two major frameworks, the Meijer Criteria and the VALGENT framework.[13](https://pmc.ncbi.nlm.nih.gov/articles/PMC10046242/)\n\n## Origin\n\nThe earliest published work on self-assessment for HPV DNA screening is a 1999 Lancet report by Peter Hillemanns and colleagues on screening for cervical neoplasia by self-assessment for human papillomavirus DNA.[14](https://doi.org/10.1016/s0140-6736%2899%2904110-0) In 2000, [Thomas C. Wright](https://www.edgepedia.org/thomas-c-wright), Jr published in JAMA a study comparing self-collected HPV testing with cytologic screening to detect cervical cancer.[15](https://doi.org/10.1001/jama.283.1.81) The first directly retrieved primary validation evaluated self-collection of cervicovaginal cells with a Dacron swab for HPV DNA detection by PCR in 268 women, concluding that a self-collected swab is a technically feasible alternative to clinician-administered collection.[9](https://pubmed.ncbi.nlm.nih.gov/11219778/) A 2004 prospective study by C. Dannecker and colleagues in Annals of Oncology found 78% of 560 women in German internal medicine outpatient clinics performed self-sampling, with post-correction sensitivity of 100%, specificity 71%, and PPV 10% for CIN2-3.[16](https://doi.org/10.1093/annonc/mdh240)\n\nEvidence accumulated through meta-analyses. Marc Arbyn and colleagues published a meta-analysis of HPV testing accuracy on self-collected versus clinician-collected samples in The Lancet Oncology in 2014,[17](https://doi.org/10.1016/s1470-2045%2813%2970570-9) and updated meta-analyses of accuracy and participation in the BMJ in 2018.[4](https://www.bmj.com/content/363/bmj.k4823) By 2018, Australia and the Netherlands had introduced self-sampling into national screening guidelines.[4](https://www.bmj.com/content/363/bmj.k4823)\n\n## Variants\n\nThe four main device forms are cervicovaginal brushes, vaginal swabs, lavage devices, and tampon-like or patch devices; brush- and swab-based devices were slightly more sensitive (98%, 95% CI 0.93–1.03) than lavage-based devices (95%, 95% CI 0.87–1.04).[13](https://pmc.ncbi.nlm.nih.gov/articles/PMC10046242/) The Evalyn brush allows dry storage and transport with reliable HPV detection.[18](https://doi.org/10.1128/jcm.01506-12) PCR (target amplification) assays perform similarly on self- and clinician-collected specimens, whereas mRNA or signal amplification tests are less sensitive on self-collected specimens.[10](https://www.asccp.org/wp-content/uploads/2026/01/ASCCP-Practice-Advisory-Self-Collection-for-Cervical-Cancer-Screening-updated_10-2-25.pdf) As of September 2025, three FDA-approved primary HPV screening tests are available for self-collection in the US: BD Onclarity (with the Copan 522C.80 dry FLOQ swab), Roche cobas (FLOQSwab or Evalyn brush), and Abbott Alinity m HR HPV (simpli-COLLECT kit or Evalyn brush).[10](https://www.asccp.org/wp-content/uploads/2026/01/ASCCP-Practice-Advisory-Self-Collection-for-Cervical-Cancer-Screening-updated_10-2-25.pdf)\n\n## Applications\n\nSelf-sampling consistently increases participation, with the size depending on how kits are offered. Across 154 studies involving 482,271 women, self-sampling nearly doubled the probability of screening uptake versus clinician-collected samples (RR 1.8, 95% CI 1.7–2.0).[5](https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2022.1003461/full) The 2018 BMJ meta-analysis found mailing kits to the home generated higher participation than invitation or reminder letters (pooled relative participation 2.33, 95% CI 1.86–2.91), while opt-in strategies were not more effective than letters (1.22, 0.93–1.61).[4](https://www.bmj.com/content/363/bmj.k4823) CIN2+ detection per 1,000 invited women was on average 2.28 times higher in the self-sampling arm than the control arm.[4](https://www.bmj.com/content/363/bmj.k4823)\n\nAgainst cytology, HPV testing of self-collected samples performs well. In the Mexican MARCH community-based randomized trial of 25,061 women in 540 underserved rural communities, HPV testing of home self-collected samples identified 117.4 women with CIN2+ per 10,000 versus 34.4 per 10,000 for cytology, a relative sensitivity 3.4 times greater (95% CI 2.4–4.9).[19](https://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2811%2961522-5/abstract) In the Dutch IMPROVE randomized non-inferiority trial, relative sensitivity and specificity of self-collected HPV testing were similar to clinician collection for CIN2+ (0.96, 1.00) and CIN3+ (0.99, 1.00).[20](https://link.springer.com/article/10.1007/s11606-025-09830-x)\n\nSeveral national programs use self-sampling at scale. The Netherlands introduced home-based self-collection for all women invited for primary HPV testing in January 2017 after a non-inferiority RCT showed clinical equivalence.[6](https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667%2825%2900304-4/fulltext) In Australia, self-collection has been available since the move to primary HPV testing in December 2017, and it became universally available in July 2022.[11](https://www.health.gov.au/sites/default/files/2025-09/national-cervical-screening-program-frequently-asked-questions-about-the-cervical-screening-test-self-collect-option.pdf) • [7](https://www.health.gov.au/sites/default/files/2025-11/final-report-for-the-self-collection-vs-practitioner-collection-project-2-scope2.pdf) In May 2024, the FDA expanded approvals for the Onclarity HPV assay ([Becton Dickinson](https://www.edgepedia.org/becton-dickinson)) and the cobas HPV test (Roche) to include self-collected vaginal specimens obtained in health care settings, and the FDA later approved an at-home self-collection kit (Teal Wand; Teal Health) for use with the Roche cobas HPV test within a proprietary telehealth primary care network.[8](https://www.ovid.com/journals/cajc/fulltext/10.3322/caac.70041~self-collected-vaginal-specimens-for-human-papillomavirus)\n\n## Limitations and alternatives\n\nInvalid samples are uncommon but real: on average 0.7% of self samples (95% CI 0.4–1.0%, range 0.0–2.7%) were unsatisfactory for hrHPV testing in the 2018 meta-analysis,[4](https://www.bmj.com/content/363/bmj.k4823) while Australian program guidance reports about 1–2% of self-collected samples produce an invalid result due to inadequate cellular material or interfering substances.[21](https://acpcc.org.au/wp-content/uploads/2024/05/24079_KI_ACPCC_10FAQs_V2.pdf) Assay choice is a second constraint: signal amplification and mRNA tests lose sensitivity on self samples, and reflex cytology triage is not recommended on self samples because of its poor accuracy.[4](https://www.bmj.com/content/363/bmj.k4823)\n\nFollow-up after a positive result is the largest operational weakness. Adherence to follow-up among self-sampling women who tested hrHPV-positive averaged 80.6% (95% CI 67.0–91.5%, range 41–100%).[4](https://www.bmj.com/content/363/bmj.k4823) Data from the Dutch national program indicate a nearly 4-fold loss to follow-up following self- compared to clinician-collection.[22](https://journals.lww.com/jlgtd/fulltext/2025/04000/self_collected_vaginal_specimens_for_hpv_testing_.6.aspx)\n\nEligibility is restricted. Self-collection is not for symptomatic individuals, surveillance after abnormal results, or groups whose screening is cytology-based (HIV-positive, DES-exposed, ages 21–24).[10](https://www.asccp.org/wp-content/uploads/2026/01/ASCCP-Practice-Advisory-Self-Collection-for-Cervical-Cancer-Screening-updated_10-2-25.pdf) In Australia, if HPV types other than 16/18 are detected on a self-collected sample, the patient returns for a clinician-collected sample for cytology, which applies to about 6% of routine screening tests.[21](https://acpcc.org.au/wp-content/uploads/2024/05/24079_KI_ACPCC_10FAQs_V2.pdf) Clinician-collected cervical specimens remain preferred for primary HPV screening of asymptomatic average-risk individuals, with self-collected vaginal specimens acceptable and repeat testing in 3 years after an HPV-negative self-collected screen.[22](https://journals.lww.com/jlgtd/fulltext/2025/04000/self_collected_vaginal_specimens_for_hpv_testing_.6.aspx)\n\n## References\n\n1.
