title: [Correlation studies of some thyroid function tests (author's transl)].
abstract: The results of a thyroid test based on ion exchange and column chromatographic separation and of two radiochemical T4 and three T3 tests were carried out with commercially available reagent packs ready for use, and were compared with the PBI values found in the same serum sample in each case. This also tested the analytical precision of each method. A good correlation was found between the PBI and the T4 values, while the accuracy of the T3 tests was unsatisfactory.
