PROBLEM TO BE SOLVED: To obtain a blood collection tube capable of suppressing reduction of a blood glucose level in collected blood and hemolysis and highly accurately and stably measuring a blood glucose level.SOLUTION: A blood collection tube 11 includes a bottomed cylindrical blood collection tube body 12 whose one end is opened and the other end is closed and a granular medicine 13 stuck to an inner wall of the blood collection tube body 12. The medicine 13 is a water soluble medicine containing glycolytic inhibitor and blood anticoagulant. The glycolytic inhibitor contains 1-5 mg of D-mannose and 0.3-1.0 mg of fluoride salt in terms of NaF quantity per 1 mL of collected blood. The blood anticoagulant is at least one sort of EDTA and/or heparin. The medicine 13 is granularly stuck to the inner wall of the blood collection tube body 12 by spray coating and drying, and an osmotic pressure of a solution obtained by dissolving the medicine 13 stuck to the inner wall of the blood collection tube body 12 with equivalent quantity of water to predetermined quantity of blood collected to the blood collection tube 11 is in a range of 30-80 mOsm.COPYRIGHT: (C)2013,JPO&INPIT【課題】採血後の血液中の血糖値の低下及び溶血を抑制でき、血糖値を高精度にかつ安定に測定することを可能とする採血管を得る。【解決手段】一端が開口し他端が閉塞してなる有底筒状の採血管本体12と、前記採血管本体12の内壁に付着されている粒子状の薬剤13とを備え、前記薬剤13が解糖阻止剤及び血液抗凝固剤を含む水溶性の薬剤であって、前記解糖阻止剤が、採取される血液1mL当たり、1~5mgのD-マンノース及びNaF量換算で0.3~1.0mgのフッ化物塩を含み、前記血液抗凝固剤が、EDTA及び/又はへパリンの少なくとも1種であり、前記薬剤13が、前記採血管本体12の内壁にスプレー塗布し乾燥させることにより粒子状で付着されており、前記採血管11に採取される血液の所定量と等量の水で前記採血管本体12の内壁に付着されている薬剤13を溶解した際の水溶液の浸透圧が30~80mOsmの範囲にある、採血管11。【選択図】図1
