ABSTRACT:
For the serodiagnosis of a fluid sample, it is particularly advantageous to use a device comprising (A) a supported, porous membrane wherein a first immunoreagent is bound so as to be capable of binding a foreign analyte and forming a complex when the foreign analyte is brought into contact therewith; and (B) a matrix which presents a first surface and an opposing second surface and which contains a second, labeled immunoreagent that is capable of binding the foreign analyte to form a labeled complex when the foreign analyte is sandwiched between the first immunoreagent and the second immunoreagent. In such a device, the first surface of the matrix is adjacent to a surface of the membrane, (ii) the matrix is wettable by or soluble in an aqueous fluid, and (iii) the second immunoreagent is mobilized when the matrix is wetted.
