Introduction

SPINA (Structure Parameter Inference Approach), a method to calculate constant structure parameters of endocrine feedback control systems from hormone levels obtained in vivo, has been applied in a prototypical implementation for the evaluation of the thyroid function.

This application allows for calculating the thyroid's maximum secretion capacity and the sum activity of the peripheral 5'-deiodinase from the levels of TSH, FT4 and FT3 determined only once.
