Abstract:
In a test device for concurrent analysis of a sample for multiple analytes on multiple test strips within said test device, wherein said test device has (a) a plurality of test strips specific for detection of distinct analytes, and (b) a common sample application site in fluid communication with each of said test strips within said test device, the improvement comprising:a test device havingA. an array of individual test strips comprising at least two individual test strips arranged essentially parallel to one another within the test device, each of said test strip being characterized as comprising a porous medium having a linear fluid pathway and a test site defined as a delimited area of immobilized test kit reagent along said linear fluid pathway of said test strip; andB. a sample receiving web having at least two segments in fluid communication with each other and a common fluid application site, said sample receiving web being further characterized as having a sample application site, a base segment and at least one branched segment radiating from said base,wherein each of said base and said branched segment are in fluid communication (a) with each other at said sample application site and (b) with each of said test strips at two spaced apart areas on said test strip, for essentially coincident distributive flow of sample from said fluid application site onto each of said two spaced apart areas of said individual test strip within said test strip array,whereby, sample applied to said sample application site on said base segment effects distribution of an aliquot of sample to each of two spaced apart areas on said test strip and thereby essentially concurrent interaction of said sample with each of said test sites of said test strips within said test strip array.
