Semi-Quantitative Lateral Flow Assays

Organization Name	STC UNM
Institutional ID Number	20178
Technology Tags or Keywords	Bioassay diagnostic
Summary	This method requires a multiple-arm pattern of flow channels. When the assay is employed in the presence of analyte, it is possible to make a semi-quantitative determination of analyte concentration.
Technology Benefit	--
Technology Applications	Ability to produce semi-quantitative test results using commercially available lateral flow assays

Detailed Technology Description	A researcher at the University of New Mexico has developed a method of generating semi-quantitative data from lateral flow assays. This method requires a multiple-arm pattern of flow channels. When the assay is employed in the presence of analyte, it is possible to make a semi-quantitative determination of analyte concentration.

Additional Information	Track Code 2012-096 Manager Erin Beaumont Background Current commercially-available lateral flow test kits are limited to answering yes/no questions such as those concerning pregnancy or influenza. Many important tests are quantitative in nature -- such as HIV loading, the extent of liver function damage, and measurements of environmental exposure -- and these cannot be answered at present by commercially-available lateral flow assays. There is a present need for the development of a diagnostic tool to obtain quantitative or semi-quantitative data from lateral flow assays.
