Abstract:
A test strip for simultaneously detecting and measuring more than one analyte in a sample comprising in the following order:(a) a distribution layer across the length of the test strip wherein a sample can be applied at any spot on the distribution layer which distribution layer breaks the surface tension of a drop of sample and permits uniform distribution of the sample across the distribution layer; (b) an optional blood filtration layer; (c) a plurality of reagent pads for each analyte to be measured, wherein each reagent pad containing dry reagents for detection of the analyte to be detected by a specific reagent pad, wherein said reagents produce a change in color proportional to the concentration of the analyte detected in the sample; (d) a support for the reagent pads wherein changes in the color of the reagent pads can be viewed; (e) a light measuring device comprising a light source for each reagent pad and a light detector source for each reagent pad enabling simultaneous measurement of each reagent pad.
