Accuracy of HPV Testing Using Self-collected Urine Compared With Physician-collected Cervical Specimen for HSIL or Worse
Chen et al.
The finding, in our words
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.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
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.
The OncoPredict HPV Quantitative Typing assay achieved clinical sensitivity ratios of 0.99 for urine and 1.00 for vaginal self-samples versus clinician-collected cervical samples for detecting CIN2+, and after cut-off optimisation showed similar accuracy on self-collected and cervical specimens, supporting decentralised cervical screening through urine self-collection with Colli-Pee.
In women with HPV, first-void urine collected with the Colli-Pee device had higher HPV DNA concentrations than urine collected with a standard cup, although this advantage disappeared at high HPV DNA loads. Timing of collection (morning versus later) did not affect HPV DNA copies.
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 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.
