Thyroid Function Studies of Healthy Koreans and Patients with Thyroid Disease by means of I131-triiodothyronine.

Abstract

The in vitro erythrocyte uptake of IJ31-TRI was determined in normal Korean subjects and patients with thyroid diseases. Concomitantly. other laboratory tests currently in use were performed in patients. 1. Erythrocyte uptake of I-13ITRI averaged 15.7±3.24 percent in normal males and 14.4±3.56 percent in normal females. No significant difference in erythrocyte 1131-TRI values according with various geographical areas of Korea was found. 2. Erythrocyte uptake of IJ3LTRI was decreased during pregnancy and restored after delivery. 3. Accuracy of erythrocyte P3LTRI uptake test as a diagnostic aid was compared with that of other currently used methods in patients with toxic and nontoxic goiter. 4. The value of erythrocyte 113LTRI were significantly decreased in hypothyroid patients and ad· ministration of thyroid extract resulted with the increase in the value.
