The present invention provides a device, method, and program for detection of a biomarker candidate that may be used in a diagnosis of a pre-disease state indicating a transition from a healthy state to a disease state. Biological samples are collected from a subject to be measured at different times. Statistical data is obtained by aggregating measurement data obtained in measurement on collected biological samples. Thereafter, a process of obtaining high-throughput data (s), a process of choosing differential biological molecules (s), a process of clustering (s), a process of choosing a DNB candidate (s), and a process of identifying a DNB by significance analysis (s) are carried out.

Device for detecting a dynamical network biomarker, method for detecting same, and program for detecting same

The invention provides a detection device, method, and program capable of highly accurately detecting a pre-disease state that indicates a precursor to a state transition from a healthy state to a disease state. The following processes are carried out: a process of obtaining measured data on genes, proteins, etc. related to a biological object as high-throughput data (s), a process of selecting differential biological molecules (s), a process of calculating the SNE of a local network (s), a process of selecting a biomarker candidate (s), a process of calculating an average SNE across the entire network (s), and a process of determining and detecting whether or not the system is in a pre-disease state (s).
