A patient's thyroid gland exhibits sustained iodine trapping deficiency despite normal TSH levels. Which consequence follows from impaired thyroid peroxidase function?

💡 Explanation

Iodine trapping enables thyroid hormone synthesis by incorporating iodine into thyroglobulin. Impaired thyroid peroxidase inhibits this crucial step, because the organification process requires peroxidase; therefore, reduced hormone production happens, rather than increased synthesis or altered T4/T3 conversion.
