Estimation of serum thyroid stimulating hormone in patients undergoing high dose I-131 therapy after two weeks of thyroidectomy

Patients with thyroid cancer (papillary or follicular) can be surgically treated by removing thyroid gland and leaving recurrent tissues to protect the laryngeal nerve, followed by I-131 radio ablation therapy on the basis of I-131 pre therapy scan. The above mentioned are the maximum and minimum serum TSH levels for different age groups. Hence from the results it is evident that the ATA guidelines of TSH > 30 can be achieved within two weeks. Within two weeks after thyroidectomy, the serum thyroid stimulating hormone (TSH) levels of patients was above 30 mIU/L. So here we can conclude that we can administer I-131 to patients after two weeks of post thyroidectomy and so there is no need of waiting for three to four weeks
