title: [Value of separation on ion exchange resins of plasma iodine fractions. Comparison with Werner's suppression test].
abstract: This was a study of 71 patients suspected of hyperthyroidism who had undergone a tri-iodothyronine suppression test. A study of circulating protein-bound iodine after separation on ion-exchange resins had been carried out before triiodothyronine administration, on the same patients. The results showed that the radioactive hormonal fraction has a better diagnostic value than radioactive serum protein-bound iodine. In 60% of cases, a study of the radioactive hormonal fraction could have permitted to avoid the use of the suppression test.
