Her past medical history is significant for hypothyroidism, which was diagnosed four years ago. She takes L-thyroxine, and the dose of the hormone has been stable for the last several years. Her blood pressure is 120/70 mmHg and heart rate is 80/min. Physical examination is insignificant. Which of the following actions related to the control of hypothyroidism is the most reasonable next step in the management of this patient?
