Abstract

A structure for controlling fluid flow from a sample receiving pad into a lateral flow assay test strip, including: a lateral flow assay test strip; a sample pad abutting the lateral flow assay test strip; a pinch wall positioned to direct fluid flow from the sample pad to the lateral flow assay test strip; a top support structure positioned on top of the test strip; and a bottom support structure positioned underneath the test strip, wherein each of the top and bottom support structures comprise a plurality of separate spaced-apart support ribs positioned along the length of the test strip.
