A point-of-care testing (POCT) system is a medical diagnostic approach that allows healthcare professionals to perform rapid, on-site diagnostic tests at or near the location where patient care is provided, rather than sending samples to a centralized laboratory.  

Molecular POCT system is particularly valuable in the context of respiratory disease diagnostics,given the device is easily assessable, produce results rapidly, and its closed system can reduce virus transmission. Common molecular POCTplatform can detect various respiratory pathogens like influenza viruses, respiratory syncytial virus (RSV), and SARS-CoV-2. These ensures the system delivers quick and actionable results, enabling faster decision-making and treatment.
