Iodine deficiency lowers circulating thyroxine (T4) and raises serum Thyroid Stimulating Hormone (TSH), where free T4 (fT4) and TSH have strong corelation with thyroglobulin (Tg). The results from population studies indicate, Tg appears to be a valuable indicator of thyroid status, but it has yet to be fully explored. This study aimed to measure the association between serum Tg with TSH and fT4…
