Part of the Monographs on Endocrinology book series (ENDOCRINOLOGY, volume 18)


The availability of sensitive, rapid, and precise methods for the measurement of T3 and rT3 has been a key factor responsible for the recent major improvements in our understanding of thyroid hormone physiology. This chapter reviews some methods of measurement and data regarding T3 concentrations in the serum and/or amniotic fluid of healthy individuals, those with thyroid disease, and in those with nonthyroidal systemic diseases. The data on serum T4 levels are also described when considered relevant to the understanding of the nature and/or the basis of the changes in the levels of circulating thyroid hormone levels in various circumstances.
