A United States study of self-collected urine vs clinician-collected cervical sample for HPV and cervical intraepithelial neoplasia grade two or worse detection: Cross-sectional agreement and diagnostic accuracy study
Young et al.
The finding, in our words
First-void urine self-collection achieved almost perfect agreement with clinician-collected cervical samples for high-risk HPV detection (prevalence-adjusted kappa 0.95 for HPV16). The method showed comparable sensitivity and specificity ratios for identifying cervical intraepithelial neoplasia grade two or worse, supporting its use as a decentralised screening alternative.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
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.

This meta-analysis found that self-collected urine samples for HPV testing had lower sensitivity for detecting high-grade lesions compared to physician-collected cervical specimens. The use of a first-void collection device such as Colli-Pee was associated with marginally higher sensitivity than general urine sampling.

Vaginal self-sampling achieved higher pooled sensitivity and specificity than urine self-sampling for detecting high-risk HPV, making it the preferred option, while urine self-sampling remains a useful non-invasive choice for under-screened populations.
For decentralised testing, a study found dry vaginal self-samples using Copan FLOQSwabs stored up to two weeks at room temperature maintain DNA quality. However, first-void urine collected with the Colli-Pee device may be less sensitive for HPV detection, showing lower positivity and higher cycle threshold values, median Ct 30 versus 27 for other samples.

Genital swabs demonstrated a significantly higher human papillomavirus positivity rate than self-collected urine samples or urethral swabs in men, suggesting that urine may be a less sensitive matrix for screening in this population.
