Lateral flow assay test strip and method of making the same

Timo Lappalainen (Inventor)

Research output: PatentPatent


The invention relates to a lateral flow assay test strip and a method for making the same. The strip comprises, in the flow direction, a selectively activated membrane for a test reaction and an absorption pad, which are both made of paper and may comprise an integral paper strip. The absorption pad has the paper strip embossed and/or folded to increase the strip's absorption capacity. The folded pad may have an accordion-like configuration, the strip running to-and-fro, or it may have the strip rolled and then flattened to a stack of layers
