Abstract
A multiplexed lateral flow device includes an impermeable internal reservoir having an opening to receive a sample deposition. A fluid distributor pad is arranged in fluid communication with a lower surface of the internal reservoir. The fluid distributor pad includes a paper based microfluidic element having a pattern of a hydrophobic material to distribute a portion of the sample deposition substantially equally among a plurality of flow paths. Lateral flow assays having a plurality of flow lines are aligned with flow paths of the distributor pad. An impermeable top cover has a first window arranged over the opening of the internal reservoir, and at least a second window arranged over the test results of the lateral flow assays. A housing element houses the reservoir, the distributor pad and lateral flow assays. The housing element includes an impermeable bottom cover and a spacer element arranged between the top and bottom covers and, provides a gap between the lateral flow assays and the impermeable top cover.
