We found that the serum FT3 and TSH (IRMA) levels of villagers were higher and the FT4 level was lower than those of the controls, which suggested that the inhabitants of the endemic goiter area had subclinical hypothyroidism based on the ultrasensitive method for TSH assay. Therefore, we suggest that the best biochemical techniques for monitoring the iodized salt prophylaxis program and the physiological response of villagers to iodine are measurements of serum TSH level and FT4 level periodically.
