Title (EN) MULTIPLE ASSAY TEST STRIP DEVICES
(FR) DISPOSITIFS DE TITRAGE A BANDES-TEST MULTIPLES
Abstract:
(EN) The present invention provides an assay device (10) having a plurality of strips (2) affixed to one another by a handling means (4) which may (i) either contact the distal ends of the strips (2), wherein the strips (2) are separated by a distance suitable to allow the strips (2) to be simultaneously contacted to individual test samples; or, (ii) may involve a card upon which each of the strips (2) is individually mounted. The test samples travel from the proximal end (12) to the distal end of each strip (2) by capillary action, and the strips contain an immobilized capture reagent (6) which binds target analyte, an ancillary specific binding member or a labeled reagent, in proportion to the amount or presence of target analyte in the test sample. The handling means (4) simplifies the assay procedure and decreases the amount of time needed to perform a large number of assays. Preferably, a procedural control is provided on each strip (2).
(FR) La présente invention se rapporte à un dispositif de titrage (10) comportant une pluralité de bandes fixées les unes aux autres par un élément de manipulation (4) qui peut (i) soit mettre en contact les extrémités distales des bandes (2), les bandes étant séparées selon une distance appropriée pour permettre qu'elles soient mises simultanément en contact avec des échantillons-test individuels; soit, (ii) peut comporter une carte sur laquelle chacune des bandes (2) est fixée individuellement. Les échantillons-test se déplacent de l'extrémité proximale (12) vers l'extrémité distale de chaque bande (2) par action capillaire, et les bandes contiennent un réactif de capture (6) immobilisé qui fixe l'analyte cible, un élément de liaison spécifique ancillaire ou un réactif marqué, proportionnellement à la quantité ou à la présence d'analyte cible dans l'échantillon-test. L'élément de manipulation (4) simplifie le processus de titrage et réduit le temps nécessaire pour effectuer un grand nombre de titrages. De préférence, des instructions concernant le titrage sont inscrites sur chaque bande (2).
