Integrated Point-of-Care Molecular Diagnostic Devices for Infectious Diseases
Liu et al.
The finding, in our words
This review identifies sample preparation as the key bottleneck limiting rapid home testing for infectious diseases, despite advances in nucleic acid amplification and signal transduction. It emphasises saliva, blood, urine and stool as primary self-collected specimens and discusses on-chip integration strategies to simplify operation for end-users, which could transform decentralised infectious disease diagnostics.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
This review summarises progress toward integrating automated sample preparation with on-chip nucleic acid amplification for home testing of self-collected blood, urine, saliva and stool specimens. It identifies that user-friendly, combined systems may enable rapid, accurate molecular diagnostics outside central laboratories, which is relevant for decentralised infectious disease screening.

An in-house RT-qPCR primer set demonstrated superior sensitivity and specificity for SARS-CoV-2 compared with WHO and CDC primers across sputum, nasopharyngeal and saliva specimens. Sputum provided the highest sensitivity, while self-collected saliva outperformed oropharyngeal samples, supporting specimen choice as a critical factor for accurate decentralised COVID-19 testing.

This review establishes that microsampling across blood, saliva, urine and stool matrices offers validated workflows and regulatory recognition for human biomonitoring comparable to conventional methods. It finds that these decentralised approaches enhance participant acceptability and enable screening in remote or low-resource settings.
This review found saliva comparable to blood and urine for detecting viral genetic material and antibodies, supporting patient-centric monitoring and decentralised surveillance. The authors state that standardised protocols and further validation are required for routine clinical use.
This review summarises how incorporating saliva and urine into home-based point-of-care systems expands diagnostic accessibility for dengue virus, aligning with the WHO REASSURED framework for affordable and rapid testing.
