An assaying device and a method of manufacturing same are provided. The assaying device includes a unitary, absorbent membrane having multiple reagent stripes incorporated therein. The reagent stripes display an observable reaction if a sample component is present in a fluid sample being tested. The reagent stripes are deposited simultaneously on a continuous membrane ribbon and individual membranes are die cut therefrom. Each individual membrane includes commonly connected channels having die cut slots therebetween. The channels are preferably disposed perpendicularly with respect to the reagent stripes and provide means for causing contact between the fluid and reagent stripes. The present invention preferably includes a cassette for containing the membrane and for facilitating analysis of test results. During assembly of an assaying device, the unitary membrane is easily inserted into the cassette by engaging the slots with ridges in the cassette, thus minimizing a chance of error of alignment of the channels. The present invention is suitable for multiple component qualitative analysis as well as semi-quantitative analysis.
