A cheap and accessible micronutrient deficiency test will help to ensure affordability and accessibility to everyone. This will contribute to closing the gap between the status of micronutrient deficiencies between high- and low-income countries. Besides, gaps between countries, it will also help to reduce national inequalities in malnutrition. Often, cities have better healthcare infrastructure, such as laboratory facilities, and a cheap micronutrient deficiency test can help to minimize the need for the laboratory setting thereby making diagnostics available for rural areas as well. Moreover, the screening communities for micronutrient deficiencies can help to increase the health of everyone by earlier intervention and especially for those groups that are the most vulnerable, children and women of reproductive age.
