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 an insertable test strip containing a reagent enabling detection of the analyte of interest.
Claims24
A testing device for the identification of an analyte of interest, comprising:
- a) a housing having a sample application matrix for:
- i) receipt of a liquid-containing sample;
- ii) desiccation of the liquid-containing sample in situ;
- iii) rehydration of the desiccated liquid-containing sample for transfer to a testing element;
- and
- iv) a testing element aperture in the housing to receive a testing element inserted therein and hold said testing element in direct liquid-conductive communication with the sample application matrix;
- and
- b) an insertable testing element which, on insertion into the testing element aperture in the housing, is retained within the housing in direct liquid-conductive communication with the sample application matrix such that upon rehydration, resolubilized or resuspended components of the liquid-containing sample are carried from the sample application matrix to the testing element.
A testing device for the identification of an analyte of interest, comprising:
- a) a housing having
- i) a front panel having at least one sample application aperture therein;
- ii) a rear panel having at least one solvent application aperture therein;
- iii) a sample application matrix disposed between the rear panel and the front panel, the sample application matrix being in communication with the sample and solvent application apertures of the front and rear panels;
- and
- (iv) a testing element aperture in the housing to receive a testing element inserted therein and hold said testing element in direct liquid-conductive communication with the sample application matrix;
- and
- b) an insertable testing element containing a reagent enabling detection of the analyte of interest, and which, on insertion into the testing element aperture in the housing, is retained within the housing in direct liquid-conductive communication with the sample application matrix.
