Title
(EN) FECAL TEST METHOD AND DEVICE
(FR) PROCEDE ET DISPOSITIF D'ANALYSE DE MATIERES FECALES
Abstract
(EN)
Methods are disclosed for determining the presence or amount of analyte in a fecal sample. In a preferred embodiment, a fecal sample is applied to an absorbent filter that contacts an immunochromatographic assay strip which contains a high concentration of detergent. The detergent extracts a surface antigen from an enteric pathogen and color is produced by a colloidal gold and selenium reaction system.
(FR)
Cette invention concerne des procédés permettant de déterminer la présence ou la quantité d'analysat dans un échantillon de matières fécales. Dans un mode de réalisation préféré, on applique un échantillon de matière fécale sur un filtre absorbant, lequel se trouve en contact avec une languette d'analyse immunochromatographique contenant une concentration élevée de détergent. Le détergent va extraire un antigène de surface d'un pathogène entérique, tandis qu'une couleur est générée par un système de réaction colloïdal à base d'or et de sélénium.
