Two cases in which thyroid function tests were ordered appropriately but not acted upon in a timely fashion illustrate the challenges of thyroid emergencies. The patient in Case #1 had a history of hyperthyroidism and noted not taking his medications for months, yet no one addressed his abnormal thyroid function tests until hospital day 3. He had thyroid storm. In Case #2, providers neglected to follow up on the patient's abnormal thyroid function tests, even though she was taking a medication with a known risk of thyroid toxicity. She had myxedema coma.
