Re-establishment of normal radioactive iodine uptake reference range in the era of universal salt iodization in the Indian population

Abstract

Compared to the previous values, there was a considerable decrease in the RAIU values in euthyroid individuals. This was further corroborated with increase in the urinary iodine concentration and decrease in thyroid volume, attributed to successful USI programme. Further studies with a large sample from different parts of India need to be done to confirm these findings.
