PATH - Feeding Micronutrition

Assay Development and Commercialization

Success Story


Path wanted to provide an affordable, robust, user-friendly test that could be used by organizations within low and middle-income countries (LMIC) to assess the micronutrient status of local, at-risk populations.

Their Story

Improving the health of people around the world.

PATH is an international nonprofit organization, and the leader in global health innovation.  PATH saves lives and improves health by accelerating innovation across five platforms – vaccines, drugs, diagnostics, devices, and system and service innovations – that harness their entrepreneurial insight, scientific and public health expertise, and passion for health equity.

Their Objective

Determining the micronutritional state of a given population consisted of individual ELISA kits targeting five unique biomarkers. These included AGP, CRP, Ferritin, STfR and RBP-4. The process of testing individual biomarkers was very costly and required a great deal of time and sample to generate the required data needed to make informed decisions. This high resource burden associated with these methods limited many LMICs in their ability to determine the prevalence of nutritional deficiencies within their populations, plan targeted nutritional interventions, and track the effects of such efforts.

The Solution

Quansys Biosciences worked with PATH to develop a customized multiplex kit. This newly developed assay added two additional markers (Tg, HRP2) to the previously tested five analytes (CRP, AGP, Ferritin, sTfR, RBP4), resulting in a 7-plex array. When coupled with the robust Q-View™ imaging system and user friendly Q-view Software, The newly created Human Micronutrient array established a new standardized platform that can be used within low and middle-income countries.


By eliminating the need to run five separate ELISA tests, Quansys provided an affordable, robust, and user-friendly test that can be used by organizations in low and middle-income countries to better understand micronutrional deficiencies in large populations.

  • Affordable. Only 10 μl of sample are needed per 7 analytes read – minimizing the complexity and cost of specimen collection, sample preparation, and testing time.

  • Localized and Robust. The Q-Plex Imaging and Software technology is highly robust – allowing sample to be ran in the harshest of conditions.

  • User-Friendly. Simple and quick setup along with a straightforward software interface make running and imaging kits easy for any user.
