TSH in patients on thyroid replacement
—ANA POPOCA-LOGUE, PA-C, San Diego
Measuring TSH is the best way to monitor patients on thyroid replacement therapy for hypothyroid conditions. The general rule of thumb is to maintain the level between 1.0 and 2.0-2.5 mU/L, but make sure you pay attention to the patient's overall state of health; together, TSH and patient condition are the best indicators of successful replacement therapy.
