If the etiology of thyrotoxicosis is not apparent based on initial evaluation, clinicians should test for thyrotropin receptor antibodies to evaluate for Graves disease and order imaging studies such as thyroid ultrasonography to evaluate thyroidal blood flow and radioactive iodine uptake and scan to determine radioactive iodine uptake.12,21	C	Expert consensus guideline
Patients with subacute thyroiditis should be started on high-dose acetylsalicylic acid or nonsteroidal anti-inflammatory drugs as first-line therapy; corticosteroid therapy should be initiated for subacute thyroiditis in patients with severe neck pain or minimal response to acetylsalicylic acid or nonsteroidal anti-inflammatory drugs after four days.12,26	C	Expert consensus
