Abstract
This invention describes a device for assaying a dry or small volume liquid sample on a lateral flow capillary assay by utilizing a supplementary non-sample aqueous solution that will push the sample up the assay without diluting or significantly diluting the original sample. This invention enables a sample to be assayed rapidly and/or on-site when the sample is in dried or solid form, or when the liquid volume is too small to complete an assay. As an option, the device can display a colored signal when a sufficient amount of liquid sample has been collected or added to the device. The minimal liquid volume requirement of the device significantly reduces the sample collection time to a matter of seconds and resolves situations in which fluids available for collection are not abundant. Therefore, this invention allows the lateral flow test device to be a more rapid, efficient, and versatile apparatus.
