Question

Quizplus · Accepted Answer

The most appropriate test for confirming hypothyroidism is measuring thyroid hormone levels, specifically thyroxine (T4) levels. Thyroxine-binding globulin (TBG) is a protein that binds to T4 and is involved in transporting T4 in the blood. Measuring levels of TBG can help diagnose certain thyroid disorders, including hypothyroidism. Thyroglobulin is a protein produced by the thyroid gland that is used in testing for thyroid cancer. Thyroid-binding inhibitory immunoglobulin is used to diagnose Graves disease, which is a type of hyperthyroidism. Toxoplasma antibody testing is used to diagnose and monitor a parasitic infection called toxoplasmosis.
