SUMMARY The results of 450 131 I-triiodothyronine (T 3 )-resin uptake tests in euthyroid, hyper- and hypothyroid patients are described. The effects of variation in the temperature and weight of resin on 131 I-T 3 uptake are demonstrated. Limits of normality have been established for a group of 149 euthyroid patients. The 131 I-T 3 -resin uptake test in euthyroid, hyper- and hypothyroid patients has been compared with the 4 and 48 hr. 131 I neck uptake, the protein-bound iodine ( p.b.i. ) concentration and the basal metabolic rate ( b.m.r. ) as a test of thyroid status. The results suggest that, as a single test for the estimation of thyroid status, the 131 I-T 3 -resin uptake test is as reliable and more convenient than the more established test procedures.
