Abstract

A disposable immunodiagnostic system tests for marker proteins in liquid sample analytes. It includes intimately contacting passage, protein, and absorbent layers. The passage layer is non-porous and has an aperture therethrough. The protein layer is porous and operatively enables immobilization of combinable proteins thereon, as well as passage of the analyte therethrough. The protein layer has an active surface area that is aligned with the passage layer aperture. The analyte is operatively introduced onto the protein layer through the passage layer aperture. In positive results, the marker proteins are operatively bound to the combinable proteins and immobilized relative to the protein layer. In negative results, the analyte operatively passes through the protein layer, and is absorbed by the absorbent layer. A housing may also be provided. The system is constructed of a combustible material that produces non-toxic by-products upon incineration, enabling ecologically responsible disposal after diagnostic use of the system.

Description

technical field

[0001] The present invention relates to the field of immunodiagnostic detection systems, kits and devices, and more particularly, to a disposable (disposable or disposable) immunodiagnostic detection system for detecting the presence of marker proteins in liquid sample analytes. Background technique

[0002] Various diagnostic testing methods and kits have been used in clinical settings, such as immunochromatographic assays, multiplex immunoassay diagnostic systems for detecting the presence of antigens and / or antibodies, assay sample analysis devices, and rapid immunoassay test strips (test stripe). Other rapid assay detection devices and methods may be more or less known in the art, and these devices and methods may be classified into one of many forms, depending on whether the sample to be tested flows through the device, And may also depend on the pattern and / or direction of any such flow. For example, the detection device may have a dipstick (test stri...
