    • An analytical element for analyzing a specific component in a liquid sample, comprising a light-­transmissive and liquid-impermeable support having thereon successively a first reagent layer and a second reagent layer, and a porous spreading layer provided above said second reagent layer, and containing an electron transport agent, a dye-forming precursor material, an oxidized type coenzyme, a buffering agent and at least one reagent capable of converting said oxidized type coenzyme to a reduced type coenzyme through a specific component in a liquid sample, wherein said oxidized type coenzyme is contained in said porous spreading layer, and a lactate dehydrogenase inhibitor is contained in at least one of said second reagent layer and said porous spreading layer.
      According to this invention, error originating from LDH and lactic acid present in a biological liquid sample can be eliminated and the accuracy of analysis can be improved.
    • 一种用于分析液体样品中的特定成分的分析元件,包括其上连续具有第一试剂层和第二试剂层的透光性和液体不可渗透性载体,以及设置在所述第二试剂层上方的多孔扩散层, 电子传输剂,染料形成前体材料,氧化型辅酶,缓冲剂和能够通过液体样品中的特定成分将所述氧化型辅酶转化为还原型辅酶的至少一种试剂,其中所述氧化型 所述多孔扩散层中含有辅酶,在所述第二试剂层和所述多孔扩散层中的至少一个中含有乳酸脱氢酶抑制剂。 根据本发明,可以消除来自生物液体样品中存在的LDH和乳酸的误差,并且可以提高分析的准确性。
