1. A chromatographic specific binding assay strip device, comprising:

  • a laminate strip having a first side and a second side;

    a sample receiving pad, a fibrous reservoir pad disposed on said first side of said laminate strip; and

    a fibrous detection pad disposed between said fibrous sample pad, wherein said fibrous reservoir pad is disposed at the distal end of said device facilitating unidirectional capillary migration through the detection pad or membrane;

    a fibrous conjugate pad disposed on said second side of said laminate;

    wherein said laminate strip is configured to fold back at a hinge point, such that laminate strip and conjugate pad on the second side are positioned on top of the sample receiving pad;

    wherein said laminating strip separates the conjugate pad from the sample pad such that the flow path of liquid migration is slowed.
