Question of the Week
For September 29, 2015
A 24-year-old, gravida 3, para 2 woman at 18 weeks’ estimated gestation reports palpitations and is found to have a thyroid-stimulating hormone level of 5.1 μU/mL (trimester-specific reference range, 0.2–3.0). She has no family history of thyroid disease.
Physical examination reveals no thyromegaly or nodules. Her reflexes are 2+ throughout. She currently feels well, and her palpitations resolve without any treatment. Her fetus is active.
What is the most appropriate next step for this patient?
