Determination of protein-bound-radioiodine level as an index for determining the form of thyrotoxicosis

The diagnostic capabilities of the test in hyperthyroidism and its possibilities in determining the form and stage of the disease were studied on a rather ample case material of 243 patients. The major diagnostic value of the method in differentiating between euthyroid function and hyperthyroidism is pointed out. The great sensitivity of the test will allow detection of even the slightest disturbances of iodine metabolism. (author)
