Iodide uptake can be evaluated using various methodologies, including radioactive iodine uptake tests, which measure the thyroid's ability to absorb iodine from the bloodstream. In toxicological studies, assays utilizing radioactive isotopes of iodine, such as I-123 or I-131, help in assessing the impact of chemicals on thyroid function. Additionally, molecular techniques can evaluate the expression of the sodium/iodide symporter in thyroid tissues or cells.
