Overview of the Principles of Two Typical Point of Care Testing Technologies and Analysis of Design and Development Control Factors

Point-of-care-testing (POCT), as an emerging diagnostic technology, is gradually becoming an important part of the clinical diagnostic field due to its many advantages, such as ease of operation, rapid response, and portability. This paper primarily introduces two mainstream technologies in POCT: lateral flow assays and nucleic acid amplification. It covers the basic principles, applications, and quality control points in design and development, aiming to provide a technical reference for device manufacturers, researchers, and regulatory agencies.
