This test is useful in patients who had a recent iodine load or in pregnant women in whom RAI cannot be used. At present, TSH testing in the United States is typically carried out with automated platforms using advanced forms of immunometric assay. They are easy to verify, and they have only one or two common causes.

Synthetic thyroxine was first successfully produced by Charles Robert Harington and George Barger in 1926. It remains controversial whether development of the aforementioned changes in thyroid metabolism reflects a protective mechanism or a maladaptive process during illness.
