The physiology and metabolism of thyroid hormones were areas of intense research investigation during the 1970s. Radioimmunoassays were applied to study the concentration of iodothyronines in biologic fluids. These techniques proved to be highly sensitive, specific, and reproducible as well as rapid. The availability of specific radioimmunoassays led to the detection of several iodothyronines in human biologic fluids, e. g., reverse triiodothyronine (rT 3), diiodothyronines, monoiodothyronines, and acetic acid derivatives of thyroxine (T 4) and T 3, which were previously either unknown or...
