Utilizing first void urine for high-risk HPV testing for cervical cancer screening in HIV-positive women in Katete, Zambia
Kaoma et al.
The finding, in our words
First-void urine tested on the GeneXpert platform detected high-risk HPV DNA with 84.8 per cent sensitivity and 92.3 per cent specificity compared with clinician-collected cervical samples, with substantial agreement (kappa 0.77) and high patient acceptability among 100 HIV-positive women in Zambia, suggesting that decentralised urine self-sampling with an EDTA preservative could widen cervical cancer screening coverage where invasive methods deter uptake.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
Urine-based HPV testing demonstrated 74% sensitivity and 52% specificity for detecting CIN2+, with performance improving when first-void collection and PCR-based assays were used. Although less sensitive than clinician-collected cervical samples, urine testing was preferred by over 90% of women, indicating potential as a complementary screening strategy to improve uptake.
A time-resolved fluorescence assay detected HPV16-specific IgG in first-void urine with strong correlation to paired serum across four immunoassays in 225 healthy women, supporting first-void urine as a non-invasive alternative to venous blood for HPV antibody monitoring.

First-void urine IgG remained stable for at least 14 days at room temperature when stored with conservation medium. Amicon filtration with Melon Gel purification enriched HPV16-specific IgG that correlated strongly with serum levels, supporting non-invasive disease monitoring and vaccine impact assessment.
First-void urine testing detected HPV with 87% sensitivity and 89% specificity, and participants reported feeling comfortable with this self-collection method. This approach could improve uptake of cervical cancer screening in decentralised settings.
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.
