Prevalence of HPV infection among Thai schoolgirls in the north-eastern provinces in 2018: implications for HPV immunization policy

Over three years after HPV vaccination in 58 women, HPV-specific IgG was detected in 84% to 100% of first-void urine samples against 98% to 100% of serum samples, and the two correlated strongly; the authors support self-collected urine for follow-up of vaccine-induced immunity, with the caveat that only women were studied.

DNA methylation markers in first-void urine effectively detect high-grade cervical lesions in HPV-positive women, with results similar to clinician-collected samples in those over 30. This enables reliable cervical cancer screening using self-collected urine, reducing the need for invasive follow-up procedures in decentralised settings.

Urinary HPV testing using first-void urine collected with the Colli-Pee device showed substantial agreement with clinician-collected cervico-vaginal sampling and near-equivalent negative predictive value, supporting its use as a clinically credible non-invasive entry point for cervical screening in settings where low participation rather than analytical performance is the principal barrier.

First-void urine samples showed significantly higher detection rates of HPV-specific IgG antibodies compared to midstream urine, confirming the necessity of capturing the initial stream. The study found no significant difference between 10 mL and 20 mL collection volumes, indicating flexibility in device specifications for self-collection.

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.
