Disclosed is a method for analyzing a concentration state of a measurement target component in blood, the method including: obtaining a value regarding an amount of the measurement target component in a collection member in which tissue fluid has been accumulated in advance, the tissue fluid having been extracted for a predetermined extraction time period from an organism which had been subjected to a process for accelerating the extraction of the tissue fluid obtaining a value of an area under a blood concentration time curve of the measurement target component on the basis of the value regarding the amount of the measurement target component and calculating a value regarding a ratio of a time period during which a concentration of the measurement target component has exceeded a predetermined concentration relative to the extraction time period, on the basis of the value of the area under the blood concentration time curve.
