Abstract
The present invention includes devices and methods for the detection of an analyte in a fecal sample. The fecal sample test device includes a sample collection structure and sample collection housing, a detection housing, a fecal suspension solution or fecal dilution solution, a detection housing capable of attachment to the collection housing and an analyte detecting means. When attached, the collection housing permits a portion of liquid extracted sample to fluidly flow into the detection housing where the analyte detection means detects the presence or quantity of an analyte suspected of being present in the fecal sample.
Claims31
A fecal test device comprising:
- a. a sample collection structure;
- b. a sample collection housing comprising a puncturable barrier, wherein said sample collection housing is capable of reversibly housing said sample application structure;
- c. a fecal suspension solution capable of substantially dissolving or solubilizing a fecal sample;
- d. a detection housing comprising a piercing structure capable of puncturing said puncturable barrier, wherein said detection housing is capable of attachment to said sample collection housing such that said sample collection housing and said detection housing are in fluid communication, further wherein upon attachment air pressure within the sample collection housing increases;
- e. a labeled analyte binding compound capable of binding an analyte of interest, further wherein said labeled analyte binding compound is provided in a dried state and is capable of suspension upon exposure to said fecal suspension solution;
- and
- f. an analyte detection means capable of detecting a compound bound to said labeled analyte binding compound, wherein said analyte detection means is positioned within said detection housing.
A test device adapted for an immunochromographic assay for detection of an analyte in a sample comprising:
- a. a sample collection structure;
- b. a sample collection housing comprising a puncturable barrier, wherein said sample collection housing is capable of reversibly housing said sample application structure;
- c. a suspension solution capable of substantially dissolving or solubilizing a biological sample;
- d. a detection housing comprising a piercing structure capable of puncturing said puncturable barrier, wherein said detection housing is capable of attachment to said sample collection housing such that said sample collection housing and said detection housing are in fluid communication, further wherein upon attachment air pressure within the sample collection housing increases, said detection housing comprising an adaption to accept at least one immunographic test strip;
- and
- e. a labeled analyte binding compound capable of binding an analyte of interest, further wherein said labeled analyte binding compound is provided in a dried state and is capable of suspension upon exposure to said suspension solution.
