Abstract

A method for measuring target substance contained in a liquid sample is disclosed. The measurement is carried out by using a device having at least one reaction area comprising a solid phase, and the liquid sample is applied onto the reaction area through a porous member to allow for a reaction of predetermined volume of the liquid sample on the reaction area. A device used for such measurement is also disclosed. A device comprises a body having at least one reaction area comprising a solid phase, and a porous member disposed on or above the reaction area. The porous member allows for the liquid sample to be permeated therethrough.
