Abstract
A method for providing quality control on a lateral flow assay device or for triggering a process-related step, the device including a substrate having at least one sample receiving area, at least one reagent zone downstream and in fluid communication with the at least one sample receiving area, at least one detection zone downstream and in fluid communication with the at least one reagent zone and at least one wicking zone downstream of the at least one detection zone, each fluidly interconnected therewith along at least one fluid flow path. The detection material provided in the at least one reagent zone produces a detectable signal that can be tracked and monitored prior to the completion of at least one test being performed on the lateral flow assay device.
