IZiNCG keeps a global inventory of recently completed and upcoming national nutrition surveys in low- and middle income countries where plasma/serum zinc concentrations have been assessed. Countries for which published reports are available are listed below.

In 2018, plasma/serum zinc was incorporated into WHO’s Micronutrient Database, which enables data visualization. Two publications have summarized available nationally-representative data on plasma/serum zinc concentrations: Hess 2017 and Gupta et al 2020.
