    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.

    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.

    A study of 2500 women found 99.0% agreement between first-void urine and vaginal self-sampling for HPV detection using Cobas4800, with 98.1% of participants preferring urine. Although conducted in a resource-limited setting which may limit generalisability, these results support urine as a viable sample type for decentralised, patient-centric screening.

    This study found that self-collected vaginal swabs and first-void urine yielded comparable detection rates for vaccine-targeted high-risk HPV types, supporting the use of both patient-centric methods for decentralised surveillance. Vaginal swabs showed higher sensitivity for non-vaccine types, whereas urine sampling offers a non-invasive alternative.

    A comparison of human papillomavirus detection in first-void urine and cervicovaginal samples from Colombian women showed moderate prevalence but weak concordance between the two methods. Although urine-based screening offers a non-invasive alternative, its limited diagnostic performance in this study highlights the ongoing need to optimise collection and processing strategies for decentralised screening.

    A study in two UK cities found that at-home first-void urine sampling for HPV screening achieved a 59% uptake among women aged 60-79. Telephone reminders increased response by 5% compared with text messages, showing that decentralised sampling can engage older women, though response rates varied by area-level deprivation and screening history.

    First-void urine sampling detected 33% prevalence of 28 HPV types in 16-21-year-old Ugandan females. HPV16/18 prevalence was markedly lower among vaccinated participants (1.4%) than unvaccinated (5.6%), though vaccine coverage was suboptimal with inconsistent dosing. This validates patient-centric urine microsampling for decentralised infectious disease surveillance in resource-limited settings.

    In pregnant women, first-void urine collected at midgestation detected HPV in 38%, with high-risk genotypes and high viral loads associated with placental HPV infection at delivery (prevalence 3%). No increased risk of adverse pregnancy outcomes was observed with placental HPV. This demonstrates urine-based HPV screening can identify placental infection risk non-invasively.

    First-void urine and anatomical-site swabs identified multiple STI coinfections in an HIV-positive homosexual man, with rectal swabs detecting all four pathogens. The case supports decentralised screening of high-risk groups for concurrent sexually transmitted infections.

    The study found that first-void urine PCR detected urogenital mycoplasmas DNA in 28.2% of men with genitourinary diseases versus 14% in healthy controls (p=0.05). This demonstrates the clinical utility of first-void urine sampling for identifying STI-associated pathogens in patients with genitourinary conditions, supporting its use in decentralised diagnostic workflows.

    Handelsman et al. validated a direct LCMS assay for pregnanediol glucuronide in dried urine spots without deconjugation. In ten women monitored across one menstrual cycle, using two or three consecutive first-void samples reduced false-negative ovulation detection from eight per cent to 2.6 per cent and 1.9 per cent respectively, enabling accurate home-based fertility assessment.

    Residual pooled rectal/pharyngeal/first-void urine specimens and residual rectal swabs showed 89% and 88% concordance respectively with dedicated anal swabs for HPV DNA detection, with marginally higher positivity rates. This demonstrates that leftover STI test material can reliably be repurposed for HPV prevalence monitoring in men who have sex with men, enabling decentralised public health surveillance without additional patient burden.

    NAAT on first-void urine is essential for identifying the cause of urethritis; dysuria is the most common symptom and purulent discharge is typical of gonococcal infection whereas transparent discharge suggests non-gonococcal pathogens, guiding decentralised diagnostic pathways.

    The study identified differential expression of urine-circulating microRNAs in five Chlamydia trachomatis-positive women with recurrent spontaneous abortion versus controls, with miR-16 showing 4.3-fold upregulation. This supports first-void urine as a viable non-invasive specimen for molecular screening of infection-related reproductive complications in decentralised settings.
