Abstract
A 54-yr-old African-American woman was seen at an urgent care facility because of the recent development of palpitations. When examined, she was noted to have a pulse of 100 bpm. Her thyroid was normal in size, and the rest of the physical examination was normal. Thyroid function tests were as follows: T4 14 μg/dL, T3RU 43% (25–35), thyroid-stimulating hormone (TSH) 1.6 mU/L. These results were interpreted as indicating that the patient was euthyroid, and she was started on a (β-blocker for symptomatic relief. However, one of the physicians in the urgent care center felt that the thyroid function tests were somewhat inconsistent, and called for further advice.
