Comparison of diagnostic accuracy and acceptability of self-sampling devices for human Papillomavirus detection: A systematic review
Aimagambetova et al.
The finding, in our words
A systematic review of 70 studies found that 94.7% of accuracy studies reported comparable sensitivity and specificity between self-sampling and clinician collection for HPV detection, with patient acceptability ranging from 84.2% to 100% for devices including Colli-Pee. This evidence endorses decentralised cervical screening to improve uptake.

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.

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.

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.

In 498 women living with HIV, self-collected first-void urine and vaginal samples showed 78% high-risk HPV prevalence and good genotype concordance, kappa 0.64-0.78. Participants preferred the Colli-Pee device over the Evalyn Brush, supporting decentralised, patient-centric screening feasibility.

Urine self-sampling for HPV showed non-inferior specificity to cervical samples, 85.19%, and found 96% of high-grade lesions. While acceptable, a survey of 1382 participants found 41.6% preferred conventional screening, showing the importance of offering choice in a decentralised, patient-centric programme.
