Performance and Diagnostic Accuracy of a Urine-Based Human Papillomavirus Assay in a Referral Population
Cuzick et al.
The finding, in our words
The Trovagene HPV test on self-collected urine samples showed sensitivity only modestly lower than on clinician-collected cervical samples for detecting high-grade cervical lesions, with 82.6% overall agreement between the two matrices. This patient-centric approach could improve screening coverage among women who do not attend for cervical screening, though the study's referral-population setting warrants validation in a general screening cohort.
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.

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.
