Results are presented from measurements of the radioactive iodine uptake in 177 subjects. Of this number 60 were normal, 41 presented goiter but were clinically euthyroid, 48 were hyperthyroid, 8 were hypothyroid, and 20 were suffering from other diseases. Measurements of radioiodine uptake were made over the thyroid at the end of the 1st, 2nd, 6th, 24th, and 48th hour. It was concluded that for practical and routine diagnostic tests the 24-hour uptake is sufficiently reliable. Simultaneous measurements were also made of the protein- bound iodine-131 conversion ratio and the total accountable iodide-131. An investigation was also made of the total dietary iodide inthke of the subjects over a 24-hour period. (C.H.)
