Question: Does serum Thyroglobulin Concentration be a Weak Marker of Iodine Status in a Pregnant Population with Iodine Deficiency?
Answer: Tg cannot be considered as a valid marker of iodine deficiency in pregnancy, at least in a mildly iodine-deficient environment. Further studies in a larger patient cohort with differences in iodine status, as well as studies on Tg changes after improving iodine status in pregnant women, are needed in order to corroborate these results.
A:
yes
