Performance of an affordable urine self-sampling method for human papillomavirus detection in Mexican women
Hernández-López et al.
The finding, in our words
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.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
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 study found strong agreement between self-collected urine samples tested with the INDICAID HPV assay and clinician-collected swabs tested with the BD Onclarity assay for detecting high-risk HPV. The results suggest that urine-based self-collection offers a reliable alternative for cervical cancer screening, potentially improving access for women who face barriers to standard care.

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.
