Abstract

A method comprising the steps of: (a) collecting a stool sample with the analyte and transferring a defined amount of stool sample into a prepared vessel having a sieve filter and a predetermined amount of extraction solution; (b) suspending and extracting the stool sample in the extraction solution so that the analyte goes into solution; (c) filtering the extraction solution through the sieve filter and transferring a defined amount of extraction solution to a cellulosic fibrous web having predetermined absorbency; (d) rapid drying of the extraction solution on the cellulose fibrous web at ambient temperature by the capillary action of the fibrous web, wherein the fibrous web with the sample extraction solution represents a storage and transport form stable over days and weeks, on which analyte and digestive enzymes are physically separated from each other; (e) collecting and extracting the analyte from the fibrous web in a predetermined amount of assay buffer; (f) separating the fibrous web from the assay buffer with the analyte; and (g) quantitatively or qualitatively determining the analyte in the assay buffer.
