Prevalence and Risk Factors for Rectal and Urethral Sexually Transmitted Infections From Self-Collected Samples Among Young Men Who Have Sex With Men Participating in the Keep It Up! 2.0 Randomized Controlled Trial

This randomised trial found that peer-delivered HIV self-testing and sexually transmitted infection self-sampling did not improve oral pre-exposure prophylaxis adherence among transgender women in Uganda compared to standard care. Adherence was monitored using dried blood spots and urine, which showed a strong correlation in tenofovir detection.

Urine microsampling for HPV DNA shows high correlation with cervical infections and enables home self-collection, which simplifies follow-up in vaccine efficacy trials. Establishing standardised sampling guidelines could overcome current variability and support decentralised, patient-centric monitoring of viral endpoints.

This meta-analysis found that HPV testing using self-collected vaginal and urine samples showed sensitivities of 88.6% and 81% for detecting cervical precancer. Using a standardised device for first-void urine increased sensitivity to 86.6%, supporting decentralised patient-centric screening, though data on specificity and specific commercial devices were not consistently reported.

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.

This study found that self-collected vaginal swabs and first-void urine yielded comparable detection rates for vaccine-targeted high-risk HPV types, supporting the use of both patient-centric methods for decentralised surveillance. Vaginal swabs showed higher sensitivity for non-vaccine types, whereas urine sampling offers a non-invasive alternative.
