Analytical element
摘要:
There is presented an improved simple quantitative analytical element for analysis of components in a body fluid such as blood, having a reagent layer constituted of a hydrophilic colloid containing at least one reagent reactive with a component in a liquid sample provided on a support, and also a development layer of a fibrous structure on the reagent layer on the opposite side to the support. A liquid sample can be distributed uniformly through the reagent layer to enable quantitative analysis.
