Abstract:
1. A test device for determining the presence of a ligand in a sample, comprising: a) buffer solution; b) a first sorbent strip having a first location for receiving a sample and defining a first migration path; c) a second sorbent strip distinct from said first sorbent strip, said second sorbent strip having a second location for receiving said buffer solution and at least partially defining a second migration path distinct from said first migration path and elongated relative to said first migration path; d) a conjugate supported by said second sorbent strip; e) a test site located on or in at least one of said first sorbent strip and said second sorbent strip, said test site having an immobilized ligand-binding mechanism, and said first and second sorbent strips touching each other at the test site; f) a frangible container and divider located at said second location, said frangible container containing said buffer solution, said divider directing a first amount of said buffer solution to said first sorbent strip to move said sample to said test site and a second amount to said second sorbent strip to move said conjugate to said test site upon breaking of said frangible container; and g) a housing defining a first opening adjacent said first location, a second opening adjacent said second location, and a window adjacent said test site through which said test site is viewable,
