Treating agent capable of improving blood sample difference, kit and application of treating agent

The invention discloses a treating agent capable of improving blood sample difference, a kit and application of the treating agent and the kit, and relates to the technical field of medical examination. The treatment agent comprises an organic solvent and PMSF, and by adding PMSF into a blood sample, the difference between a fresh serum sample and a plasma sample can be reduced, the detection result difference between an initially detected serum sample and a redetected serum sample can also be reduced, and the result interpretation accuracy can be improved. 本发明公开了一种具有改善血液样本差异的处理剂、试剂盒及其应用，涉及医学检验技术领域。该处理剂包含有机溶剂和PMSF，通过在血液样本中添加PMSF，可以减小新鲜血清样本和血浆样本的差异，也可以减小初测血清样本和复测血清样本的检测结果差异，有利于提高对结果的判读准确性。
