The reactivity ligand in the fluid are measured qualitatively or quantitatively quickly the device and the manner

摘要

The device described comprises a first reaction zone in which is located a membrane which is at least temporarily impermeable, designed to receive a sample of fluid to be tested and to be associated with at least one marked reagent; a second reaction zone delimited on the one hand by said membrane and on the other hand by a second membrane which is at least temporarily impermeable, comprising a solid phase containing a reference reagent; a third reaction zone which contains means for revealing the reaction. High speed qualitative and quantitative process for determining the presence of a reactive ligand in a fluid. Applications: detection of the presence, in particular, of antibodies or antigens in a biological fluid.
