If you gave a person with primary hypothyroidism (iodine deficiency) an injection of TSH would T3 and T4 levels increase? Why or why not?

Solution

Primary hypothyroidism is a type of auto immune disease. In this disease antibodies will be produced against TSH. So if we give injection of TsH there will be no increase of T3 and T4 because it also requires iodine for its manufacturing. Hypothyroidism is due to the deficiency of iodine and increasing levels of TSH.
