PROBLEM TO BE SOLVED: To provide a method and a device for simply and efficiently performing extraction and detection/quantitation of an organism-derived stain without dismantling an inspection object and without giving the inspection object a physical stress that may cause malfunction in the inspection object.SOLUTION: An organism-derived stain detection/quantitation method according to the present invention is for performing the detection/quantitation of the organism-derived stain adhered to the inspection object. The method includes an extraction process of extracting the organism-derived stain by bringing the inspection object into fluid contact with an extract containing a surfactant, and a detection/quantitation process of subjecting the extracted organism-derived stain to detection/quantitation. An organism-derived stain detection/quantitation device 1 according to the present invention comprises extraction means 10 that extracts the organism-derived stain by bringing the inspection object 11 into fluid contact with the extract containing the surfactant, and detection/quantitation means 20 that subjects the extracted organism-derived stain to detection/quantitation. The extraction means 10 includes a container 12 that stores the inspection object 11 and supply means 13 that continuously supplies the extract into the container 12.SELECTED DRAWING: Figure 1【課題】検査対象物を分解することなく、また故障の原因となる物理的ストレスを検査対象物にかけずに、簡便かつ効率よく生体由来汚れを抽出して検出定量する方法および装置の提供。【解決手段】本発明の生体由来汚れの検出定量方法は、検査対象物に付着した生体由来汚れを検出定量する方法であって、前記検査対象物に界面活性剤を含む抽出液を流動的に接触させて、生体由来汚れを抽出する抽出工程と、抽出した生体由来汚れを検出定量する検出定量工程とを有する。本発明の生体由来汚れの検出定量装置１は、前記検査対象物１１に界面活性剤を含む抽出液を流動的に接触させて、生体由来汚れを抽出する抽出手段１０と、抽出した生体由来汚れを検出定量する検出定量手段２０とを具備し、前記抽出手段１０は、前記検査対象物１１を収容する容器１２と、前記容器１２に前記抽出液を連続的に供給する供給手段１３とを備える。【選択図】図１
