Abstract:
1. A vertical flow through assay test apparatus comprising: a first member comprising a first, porous, membrane to which is bound a capture analyte for binding to a reagent to be detected, the member having an upper surface and a lower surface; a second member being a body of absorbent material disposed below and touching the lower surface of the first member; a vessel for containing a liquid sample spaced above the first member said vessel having side walls and a base, the base being defined by a second membrane, the vessel being capable of retaining a liquid sample for a predetermined incubation period; and means for supporting the vessel above the first member in two positions, a first position in which the membrane is spaced a sufficient distance from the first member so as to not permit fluid transfer from the vessel to the body of absorbent material, and a second position in which the second membrane is in contact with the first member, such contact permitting fluid transfer from the vessel through the first and second membranes to the body of absorbent material.
