Quansys Technologies and PATH have partnered to develop a "Multiplexed Micronutrient Assessment Tool" (MMAT) to evaluate micronutrient malnutrition. Quansys, in Utah, and PATH, out of Washington state, are working together to join their biotechnological and global health expertise. Quansys Technologies has developed a 96 well-plate antibody assay using the common enzyme assay, ELISA. They test for 5 key biomarkers, including iron, vitamin A, and inflammation.
In 2011, the MMAT was externally validated in India, Burundi, and Vietnam.
