Significant global progress has been made in the past two decades to reduce iodine deficiency disorders through universal salt iodization programs. To ensure sustained success, careful monitoring of iodization levels at production, importation and end- consumption is critical. To simplify the monitoring process, several electronic rapid test kits for quantitative salt iodine content analysis, have been developed and are mostly commercially available. GroundWork is collaborating with the Micronutrient Initiative and other stakeholders on the comparative validation of a series of such devices. This validation will include both typical laboratory performance assessments and the user- and field-friendliness of devices, including challenges of procurement, training requirements, and waste disposal procedures. The project aims to provide device-guidance based on specified use for organizations and professional staff advancing universal salt iodization.
