Self-sampling for HPV genotyping: a study of vaginal and urine collection in Brazilian women with high-grade lesions

A study of 2500 women found 99.0% agreement between first-void urine and vaginal self-sampling for HPV detection using Cobas4800, with 98.1% of participants preferring urine. Although conducted in a resource-limited setting which may limit generalisability, these results support urine as a viable sample type for decentralised, patient-centric screening.

First-void urine and self-collected vaginal swabs showed similar sensitivity and specificity to clinician-collected cervical samples for high-risk HPV detection across two real-time PCR assays, supporting their use as decentralised, patient-collected alternatives; most women preferred first-void urine for regular cervical screening.

This randomised sub-study found return rates of 10.4% for Colli-Pee, 10.1% for FLOQSwabs and 7.4% for Evalyn-Brush. All devices yielded sufficient DNA with low invalid rates, but the authors noted the study was limited by low overall participation.

In 498 women living with HIV, self-collected first-void urine and vaginal samples showed 78% high-risk HPV prevalence and good genotype concordance, kappa 0.64-0.78. Participants preferred the Colli-Pee device over the Evalyn Brush, supporting decentralised, patient-centric screening feasibility.

Urine self-sampling for HPV showed non-inferior specificity to cervical samples, 85.19%, and found 96% of high-grade lesions. While acceptable, a survey of 1382 participants found 41.6% preferred conventional screening, showing the importance of offering choice in a decentralised, patient-centric programme.
