IZiNCG keeps a global inventory of recently completed and upcoming national nutrition surveys measuring plasma/serum zinc concentrations. The countries and link to survey report are listed below.

In 2018, plasma/serum zinc was incorporated into WHO’s Micronutrient Database, which enables data visualization.
