Abstract:
1. A test strip having an ability of separating a solid from a specimen comprising the solid and a liquid to detect a substance to be detected in the liquid, said test strip comprising: a reagent layer having a porous structure comprising beads, an inorganic gel, and a reagent that causes a detectable reaction with the substance to be detected to produce a reaction product; and a substrate that supports the reagent layer, wherein the beads are adhered to each other with the inorganic gel and the inorganic gel forms interstices between the beads for trapping the solid components, and further wherein the inorganic gel does not swell and acts as an agent for bonding the beads and can retain the interstices between the beads constant after adsorption of the liquid.
