The rapid and accurate detection of the presence of microorganisms, such as viruses, has been an important issue in the fields of public health, as well as agriculture. A PCR‐based detection method has been developed and applied in these fields to determine the presence of specific pathogens. Although the major advantage of real‐time PCR is the monitoring of amplification and ability to quantify the template genes, the method described here should solve the problem of nonspecific product synthesis. We obtained viral RNA from infected samples by freezing and thawing; we rapidly synthesized cDNA from RNA, and then amplified the cDNA by rapid PCR in 10 Min. Finally, the PCR products were hybridized and quickly confirmed to be the target analyte on a DNA chip. Our newly proposed methods overcome the drawbacks of PCR‐based detection and provide three additional advantages, namely, rapidly obtaining large amounts of RNA from samples, quickly detecting infective or pathogenic genes, and speedily confirming the detected exogenous genes. This application might be useful for detecting viral RNA and for the diagnosis of RNA virus‐mediated diseases.
