A test strip having the capability of separating blood cells from whole blood, wherein it has a porous reagent layer comprising beads, an inorganic gel and a reagent that causes a detectable reaction with a substance to be detected, and a substrate that supports the reagent layer, wherein the beads are adhered to each other with the inorganic gel, and interstices are formed between the beads to trap a solid. The test strip can thus be used for separating blood cells from a whole blood including blood cells and plasma and detecting a substance to be detected, such as glucose, contained in plasma. The use of the test strip allows the measurement of a substance to be detected even by measurement of a transmitted light, the exhibition of good oxygen permeability, and thus can be used for measuring a substance to be detected with improved accuracy.
一种能从全血中分离血细胞的试纸,它具有一个多孔试剂层,该试剂层由微珠、无机凝胶和能与待检测物质发生可检测反应的试剂组成,以及一个支撑试剂层的基板,其中微珠与无机凝胶相互粘附,微珠之间形成间隙以吸附固体。因此,该试纸可用于从包括血细胞和血浆在内的全血中分离出血细胞,并检测血浆中的待检测物质,如葡萄糖。使用该试纸甚至可以通过透射光的测量来检测某种物质,显示出良好的透氧性,从而可以更准确地测量某种待检测物质。
