Title (EN) A LATERAL FLOW ASSAY TEST STRIP AND A METHOD OF MAKING THE SAME
(FR) BANDE D'ÉPREUVE DE DOSAGE À ÉCOULEMENT LATÉRAL ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) The invention relates to a lateral flow assay test strip (1, 7) and a method for making the same. The strip comprises, in the flow direction, a selectively activated membrane (4) for a test reaction and an absorption pad (5), which are both made of paper and may comprise an integral paper strip (7). The absorption pad (5) has the paper strip (7) embossed and/or folded to increase the strip´s absorption capacity. The folded pad (5) may have an accordion-like configuration, the strip running to-and-fro (9), or it may have the strip rolled and then flattened to a stack of layers.
(FR) Cette invention concerne une bande d'épreuve de dosage à écoulement latéral (1, 7) et son procédé de fabrication. La bande comprend, dans le sens d'écoulement, une membrane à activation sélective (4) pour une réaction d'épreuve et un tampon d'absorption (5), qui sont tous les deux en papier et peuvent comporter une bande de papier intégrale (7). La bande de papier (7) est gaufrée et/ou pliée dans le tampon d'absorption (5), ce qui permet d'augmenter la capacité d'absorption de la bande. Le tampon (5) peut être plié en accordéon et enfermer la bande entre chaque pli (9), ou il peut être enroulé avant d'être aplati, la bande se présentant alors sous forme de couches empilées.
