Clinical and analytical evaluation of high-risk HPV testing on Colli-Pee first-void urine using the VALHUDES protocol

An independent VALHUDES evaluation found HPV screening on Colli-Pee first-void urine detected high-grade cervical lesions with sensitivity comparable to clinician-collected cervical samples, reinforcing urine self-sampling for cervical screening.

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 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.

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 EUROArray HPV test achieved similar sensitivity and specificity for CIN2+ detection using first-void urine and vaginal self-samples compared with clinician-collected cervical samples, supporting the use of self-collection for cervical screening.
