Abstract
Disclosed is a testing device and methods for the identification of an analyte of interest in a sample. In a preferred embodiment, the testing device includes a front panel having at least one sample application aperture; a rear panel having at least one solvent application aperture; a sample collection matrix disposed between the rear panel and the front panel, the sample collection matrix being in communication with the sample and solvent application apertures of the front and rear panels; and at least one insertable test strip containing a reagent enabling detection of the analyte of interest.
Claims16
A method for identification of an analyte of interest, comprising:
- a. providing a testing device comprising a housing, wherein said housing comprises a) a sample application matrix comprising a desiccated sample, and b) at least one aperture in said housing to receive a testing element and hold said testing element in direct liquid-conductive communication with the sample application matrix;
- b. inserting at least one testing element to said at least one aperture in said housing;
- c. rehydrating said desiccated sample by applying sufficient solvent such that an analyte of said sample is resolubilized or resuspended, and wherein said testing element is contacted by said analyte;
- and
- d. identifying said analyte using said testing element.
A method for identification of an analyte from a plurality of samples, comprising:
- a. providing a testing device comprising a housing, wherein said housing comprises a) a sample application matrix, wherein said sample application matrix comprises a plurality of desiccated samples applied at discrete locations on said sample application matrix, and b) an aperture in said housing to receive a insertable testing element and hold said testing element in direct liquid-conductive communication with said sample application matrix;
- wherein said sample application matrix and said aperture are configured such that said plurality of samples are combined and flow onto said testing element upon rehydration of said samples;
- b. inserting an insertable testing element into said aperture in said housing;
- c. rehydrating said desiccated samples by applying sufficient solvent, wherein analytes from said samples are aggregated and flow onto said testing element;
- d. identifying said analyte in the aggregated sample using said testing element.
