This study presents an integrated, portable diagnostic system comprising a low\u2010cost microfluidic chip and a fully automatic, portable device for simultaneously detecting nine samples. The aim is to achieve rapid on\u2010site detection of African swine fever virus (ASFV) nucleic acid. The system integrates magnetic bead nucleic acid extraction, transfer, loop\u2010mediated isothermal amplification (LAMP), and optical detection functions, and can perform fully automatic, closed\u2010tube analysis of 9 samples in 25\u2009min, effectively avoiding aerosol pollution. The detection limit for the ASFV\n                    <jats:italic>P10<\/jats:italic>\n                    gene is 10\n                    <jats:sup>2<\/jats:sup>\n                    \u2009copies\/\u03bcL. In a blind test involving 87 clinical samples, the system demonstrated excellent performance with a clinical sensitivity and specificity of 97.6% (42\/44) and 98.0% (42\/43), respectively, and an accuracy of 96.6% (84\/87). When the sample concentration exceeds the detection limit, sensitivity can reach 100 %. The core advantages of this method are that it is fast, accurate, and low cost, and does not require professional laboratories or operators. Its modular design makes it easy to expand to a 100\u2010channel, high\u2010throughput detection system at low cost. This system provides a powerful technical tool for large\u2010scale epidemic screening and prevention in areas with limited resources, offering significant public health and economic value.\n
