METHOD FOR SELECTING PANCREATIC DISEASE MARKER DETECTION DUODENAL FLUID SPECIMEN AND METHOD FOR DETECTING PANCREATIC DISEASE MARKER

PROBLEM TO BE SOLVED: To provide a method for selecting a specimen that is highly likely to have pancreatic juice contained from a plurality of duodenal fluid specimens collected from the same test subject, and is more suitable for detecting a pancreatic disease marker, and to provide a method for detecting the pancreatic disease marker by using the duodenal fluid specimen selected by the method.SOLUTION: A method for selecting a pancreatic disease marker detection duodenal fluid specimen has the steps of: (a) comparing a color concentration of a plurality of duodenum fluid specimens collected from the same subject; and (b) selecting the maximum color concentration from the plurality of the duodenum fluid specimens as a specimen to be used for detecting a pancreatic disease marker on the basis of a result of the previous step (a). 【課題】同一被検者から採取された複数の十二指腸液試料から、膵液が含まれている可能性が高く、膵疾患マーカー検出により適した試料を選定する方法、及び当該方法により選定された十二指腸液試料を用いて膵疾患マーカーを検出する方法の提供。【解決手段】（ａ）同一被検者から採取された複数の十二指腸液試料の色の濃さを比較する工程と、（ｂ）前記工程（ａ）の結果に基づき、前記複数の十二指腸液試料の中から最も色の濃い試料を、当該膵疾患マーカーの検査に供する試料として選定する工程と、を有することを特徴とする、膵疾患マーカー検出用十二指腸液試料の選定方法。【選択図】なし
