Abstract
EUthyroid aims to harmonise IDD related studies by improving their overall quality and comparability. For this aim, a guidance document for researchers was developed, serving as a practical tool for research professionals planning and conducting population studies, especially monitoring studies.

The guide is divided into three parts:

Part A includes general recommendations and issues related to study planning.

Part B offers detailed instructions and recommendations for specimen collection and sample handling.

Part C provides an overview of laboratory analysis related to urinary iodine and thyroid function.
