TSH (thyroid stimulating hormone) increases the activity of the Sodium-Iodine Symporter (NIS) that drives iodine into the thyroid and into the cells of the other organs. That is the reason that the TSH blood levels increase when patients are taking iodine â the TSH is needed to drive iodine into the cells.
Measurement of Serum TSH Accuracy and Sensitivity of Clinical and Laboratory Assessment To place laboratory testing in perspective we need to consider the sensitivity and accuracy of clinical assessment for thyroid dysfunction. where iodine intake is marginally deficient. a two-fold change in free T4 induces inverse 10-100 fold changes in TSH. with a comparable prevalence of suppressed values indicating possible thyrotoxicosis.
