Funky TSH Results

When treating hypothyroidism, sometimes I get unexpected TSH results. Before making another adjustment to a patient's levothyroxine dose, I always double check 1) compliance with taking the levothyroxine, and 2) if they are taking their levothyroxine with vitamins, antacids, iron, or calcium supplementations (which can all decrease levothyroxine absorption in the gut).
