Ultra-rapid methods from DNA collection to detection are still not well developed (1), especially for environmental DNA (eDNA) analysis, which uses water or soil samples to track the presence of target species (2, 3) . Here, we developed a new innovative method for the field processing of eDNA samples and measurements using an ultra-rapid mobile PCR platform (hereafter, mobile PCR) to reduce the measurement time to 30 min and maintain high detectability of aquatic organisms. We compared the on-site eDNA measurement to the laboratory extraction and detection using a benchtop qPCR platform and the national survey to confirm the performance. Our ultra-rapid on-site eDNA extraction and measurement method using mobile PCR successfully detected the eDNA of H. ./cache/cord-103417-2uinislh.txt ./txt/cord-103417-2uinislh.txt
