A sample analysis method including: The photographing program photographs a test piece by the photographing section, and the test piece has an analysis area that is colored in accordance with the concentration of the substance to be analyzed in the sample on the same surface, and displays information related to the sample. region; The concentration analysis program calculates the concentration of the analysis target substance by the concentration analysis unit based on the image data of the analysis area of the test piece photographed by the photographing unit; An acquisition procedure for obtaining information related to the sample from the image data of the display area of the test piece photographed by the photographing section by an acquisition section; and The memory program stores the calculated concentration of the analysis target substance in correspondence with the information related to the obtained sample through the memory unit and memorizes it. A sample analysis system includes a terminal device and a server device that can communicate with each other. The terminal device has: The photographing unit is used for photographing a test piece, and the test piece has an analysis area that is colored according to the concentration of the analysis target substance in the sample on the same surface, and a display area that displays information related to the sample; The concentration analysis unit calculates the concentration of the analysis target substance based on the image data of the analysis area of the test piece photographed by the photographing unit; An obtaining unit that obtains information related to the sample from the image data of the display area of the test piece captured by the shooting unit; and The communication unit on the terminal side transmits the calculated concentration of the analysis target substance and the information related to the obtained sample to the server; And the server device has: The server-side communication unit receives, from the terminal device, the calculated concentration of the analysis target substance and information related to the obtained sample; and The memory unit memorizes the calculated concentration of the analysis target substance and the information related to the obtained sample. A sample analysis system includes a terminal device and a server device that can communicate with each other. The terminal device has: A photographing section for photographing a test piece, and the test piece has, on the same surface, an analysis area that is colored in accordance with the concentration of the substance to be analyzed in the sample, and a display area that displays information related to the sample; and The communication unit on the terminal side transmits the image data of the test piece photographed by the photographing unit to the server; And the server device has: The server-side communication unit receives the image data of the test piece from the terminal device; The concentration analysis unit calculates the concentration of the analysis target substance based on the image data of the analysis area in the image data of the test strip; The obtaining unit obtains information related to the sample from the image data of the display area among the image data of the test piece; and The memory unit memorizes the calculated concentration of the analysis target substance and the information related to the obtained sample. A program characterized in that a computer performs calculation steps, acquisition steps, and memory steps, wherein the computer can obtain image data of a test piece photographed by a shooting section, and the test piece has on the same side corresponding to the test piece in the sample. An analysis area where the concentration of the target substance is analyzed and colored, and a display area where information related to the sample is displayed, In the calculation step, the concentration of the analysis target substance is calculated based on the image data of the analysis area in the image data of the test strip, The obtaining step obtains information related to the sample from the image data of the display area among the image data of the test piece, In the memory step, the calculated concentration of the analysis target substance is stored in correspondence with the information related to the obtained sample.
