Subacute thyroiditis is self-limited, and in most cases the thyroid gland spontaneously resumes normal thyroid hormone production after several months. Patients with overt hypothyroidism (elevated TSH and low free T4 levels) should be treated with levothyroxine to a goal TSH level of 1 to 3 mIU per L. A starting dosage of 1.6 mcg per kg per day can be initiated, with subsequent incremental changes made every 10 to 12 weeks to achieve this goal. Answer From Todd B. Nippoldt, M.D. Our purpose was to describe the TgAb resolution time course and the significance of persistent antibody elevation after thyroidectomy.

My recent antibody levels came back 421 last week (May 30, 2013). First, the laboratory test result should be confirmed, and free thyroxine (T4) and free triiodothyronine (T3) levels should be measured. The thyroid gland is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck. To exert its effects, T4 is converted to triiodothyronine (T3) by the removal of an iodine atom. Hypothyroidism is treated by thyroid hormone and returning thyroid hormone levels to the normal range usually resolves symptoms in most patients.

However, a diagnostic dilemma occurs when the patient presents with thyroid-stimulating hormone (TSH) suppression. High antibodies indicate that a patient's symptoms are from too little thyroid hormone regulation when the TSH, T4, or T3 fail to do so.
