Advancing Cervical Cancer Prevention Equity: Innovations in Self-Sampling and Digital Health Technologies Across Healthcare Settings
Gomes et al.
The finding, in our words
Vaginal self-sampling devices detect HPV with high sensitivity, 94.6% for brushes and 82.9–100% for tampons, while improving patient comfort and reducing costs by 32–48% in resource-limited settings, supporting patient-centric cervical cancer screening programmes.

Urine self-sampling for HPV detection showed good agreement with clinician-collected cervical samples (Kappa 0.72) under optimised conditions of 40 mM EDTA preservative, storage at 25°C, and processing within 72 hours. With a cost of USD 1.10 and high acceptability among women and healthcare workers, this method offers a practical decentralised screening approach for resource-limited settings.
Self-sampling for HPV testing using urine and swab devices achieved high DNA detection rates, 92.1-99.7%, and very high participant acceptance, 99.1%, in a primary care population, supporting decentralised screening in low-resource settings.
This meta-analysis found that urine self-sampling for HPV detection had significantly lower sensitivity for high-grade lesions compared to vaginal and cervical samples, though specificity remained comparable. Despite the reduced diagnostic accuracy, the non-invasive and acceptable nature of urine sampling supports its use as a decentralised option to improve screening uptake.

Urine-based HPV testing showed broad variability in diagnostic performance, with sensitivity ranging from 44.8 to 98.6 per cent and specificity from 61 to 100 per cent against cervical specimens. High patient acceptability was reported, yet standardisation is needed before this self-collection approach can be approved for decentralised cervical cancer screening.

Urinary HPV testing showed lower sensitivity than cervical sampling for detecting CIN2+ (79% versus 93%) but higher specificity (58% versus 50%), and participants favoured urine self-collection. The authors conclude that while urine sampling may complement screening in resource-limited or culturally conservative settings, its suboptimal performance and absence of standardised protocols preclude its use for general population screening.
