Abstract

An analytical test device is described for the immunochromatographic determination of the presence of one or more analytes in fluid samples. The device is configured such that the sample is allowed to enter the detection zone simultaneously from many different directions, eliminating stagnation of the flow of the sample. By selection of the porous substrate, the device also allows for the separation of red blood cells from plasma, providing a rapid test for one or more analytes in a sample of whole blood. The device of the present invention may measure more than one analyte simultaneously from a single sample, either by having multiple immunochromatographic pathways fed by a single sample, or multiple analytes detected in the same pathway by way of multiple capture antibodies.

Description

field of invention

[0001] The present invention relates to an analytical assay device and method for determining the presence of an analyte in a fluid sample. The devices and methods are particularly useful for determining the presence of cardiac analytes in whole blood, although their application is not limited thereto. Background of the invention

[0002] The products and methods of the invention are useful for many diagnostic purposes, as well as for following the course and treatment of mammalian diseases. It is suitable for a variety of mammalian body fluids such as whole blood, serum, plasma and urine. Although the invention is primarily discussed for use in the detection of cardiac analytes, it is also applicable to other fields utilizing antigen / antibody or equivalent reactions.

[0003] Numerous related analytical operations, particularly those involving immunoassays, can be performed using the device of the present invention and its disclosed variations. For exa...
