Efficacy and role of Xpert<sup>®</sup> <i>Mycobacterium tuberculosis</i>/rifampicin assay in urinary tuberculosis
Samuel et al.
The finding, in our words
Xpert MTB/RIF assay on early morning first void urine had moderate sensitivity and high specificity for urinary tuberculosis versus a composite standard and was superior to LED fluorescent smear microscopy as the initial test, supporting its use as a decentralised diagnostic.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
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.

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.

First-void urine PCR identified Ureaplasma urealyticum in 19% of symptomatic men, alongside other pathogens, confirming that patient-collected urine samples provide valid diagnostic results for STI screening outside traditional clinical settings.
Four years after vaccination, HPV-16/18 prevalence in schoolgirls fell from 3–6% to under 0.6% for both single-dose and two-dose regimens, with single-dose effectiveness at 90.6% proving non-inferior to the two-dose schedule. This validates first-void urine sampling for community-based vaccine effectiveness monitoring in decentralised screening programmes.

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.
