Claim 11:
12. The lateral flow assay device of claim 1,
further comprising a channel base, a channel layer on top of the channel base, and a channel cover on top of the channel layer, the channel base, channel layer, and channel cover collectively defining a microchannel,
wherein a portion of the pooling layer is disposed on top of the channel cover,
wherein the portion of the pooling layer and an opening in the channel cover together laterally define an additional filtrate pooling chamber, the additional filtrate pooling chamber vertically defined between the sample pad and the channel base and fluidically connected to the microchannel, the additional filtrate pooling chamber containing an additional soluble matrix in contact with both the sample pad and the channel base, the additional soluble matrix possessing a capillary drawing force sufficient to draw additional filtrate through the sample pad and into the additional soluble matrix, causing the additional soluble matrix to at least partially dissolve or disintegrate in the additional filtrate, whereby the additional filtrate is released into the additional filtrate pooling chamber for delivery from the additional filtrate pooling chamber to the microchannel.
