Patent ID: 8475735

Claim:
A disposable immunodiagnostic test system for testing for the presence of a plurality of marker proteins in a liquid sample, said test system comprising: a passage layer comprised of a first material having a substantially non-porous structure that is configured so as to define at least one aperture therethrough; a protein layer comprised of a second material that is configured to enable immobilization of a first and a second combinable protein thereon, the protein layer having a substantially porous structure enabling a portion of said liquid sample to pass therethrough; and an absorbent layer comprised of a third material that enables absorption of at least a portion of said liquid sample, the absorbent layer being in intimate contacting relation with the protein layer; wherein the at least one aperture of the passage layer is configured to receive the liquid sample; and wherein the protein layer comprises an active surface area that is aligned with the at least one aperture of the passage layer so as to be viewable through the at least one aperture, the active surface area comprising a plurality of first test areas arranged in at first ring having a first diameter, and a plurality of second test areas arranged in a second ring having a second diameter, the second diameter being larger than the first diameter, with at least one of the first and second combinable proteins being immobilized in the first test area and at least the other one of the first and second combinable proteins being immobilized in the second test area for binding of said marker proteins with said first and second combinable proteins when the liquid sample comprises such marker proteins.
