Abstract
An embodiment includes a sample receiving region, a first diagnostic element that includes one or more colorimetric analysis regions, and a second diagnostic element that includes one or more lateral flow assay analysis regions. The embodiment also includes a first flow path that allows a portion of a liquid deposited at the sample receiving region to flow to the first diagnostic element. The embodiment also includes a second flow path that allows a portion of the liquid deposited at the sample receiving region to flow to the second diagnostic element.
Claims6
An apparatus comprising:
- a sample receiving region;
- a first diagnostic element that includes one or more colorimetric analysis regions;
- a second diagnostic element that includes one or more lateral flow assay analysis regions;
- a first distribution substrate comprising a first hydrophilic region and a first hydrophobic region that defines a boundary of the first hydrophilic region, wherein the first hydrophilic region receives liquid deposited at the sample receiving region;
- and
- a second distribution substrate comprising a second hydrophilic region that receives a first portion of liquid from the first hydrophilic region and allows the liquid to flow to the first diagnostic element, a third hydrophilic region that receives a second portion of liquid from the first hydrophilic region and is configured to allow the liquid to flow to the second diagnostic element, and a second hydrophobic region that is configured to oppose traversal of liquid from the second hydrophilic region to the third hydrophilic region.
