An injection-molded focal filter-integrated AI platform for cost-effective and highly sensitive molecular point-of-care testing
Zhang et al.
The finding, in our words
The WeD-1 Pro molecular point-of-care device, using an injection-moulded polymer filter, demonstrated 100 per cent concordance with commercial qPCR for SARS-CoV-2 and influenza in a proof-of-concept study of self-collected at-home swab samples. In routine veterinary deployment across 40 clinics, it achieved 98 per cent concordance with reference PCR for feline respiratory pathogens, showing potential for decentralised infectious disease surveillance.

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.

The study found that self-collection of dried blood spots and other samples using at-home kits was a useful and cost-effective method for screening a large cohort for sexually transmitted infections outside a clinic. This demonstrates the feasibility of decentralised, patient-centric sampling for population-level infectious disease surveillance.

This retrospective analysis of over 600,000 online postal self-sampling orders found that whilst return rates for urine samples were moderate to high, the return of processable blood samples was significantly lower and varied by age and deprivation level.

The study found that self-collected dried saliva on FishburneTabs achieved 92% accuracy for viral RNA detection compared to standard liquid saliva samples. This method supports decentralised testing by enabling reliable sample storage and transport for upper respiratory infections.

The study validated a semi-quantitative protocol for Epstein-Barr virus serology using dried blood spots, demonstrating 98.8% sensitivity and 96.5% specificity compared to paired venous serum samples. The successful validation in a self-sampling cohort confirms the suitability of this patient-centric microsampling approach for large-scale seroprevalence studies and decentralised trials.
