title: [Radioimmunologic determination and analysis for saturation of the thyroid hormones: comparison and use in the practical clinic].
abstract: Reliability of a recent method of assay by saturation analysis for assessment of thyroid status, which is to be recommended for its practicability and technical improvement, has been verified. Its diagnostic efficiency in more than 3,000 assays has been evaluated. On the whole T3 Uptake (T3U) and serum Thyroxine (T4D) determination showed a quite good accuracy, that decidely improved when both the tests were carried out and the Free Thyroxine Index (Free Thyopac Index) was drown. Moreover the present availability of the radioimmunological determinations of triiodothyronine allowed to assay simultaneously both thyroid hormones in normal euthyroid subjects, in pregnancy, in hyperthyroid, hypothyroid and goitrous patients. Results obtained have been analysed and discussed and clinical conditions pointend out where determination of both hormones may be useful.
