He has not visited the office since being prescribed this medication. Which of the following lab tests should be obtained at the present office visit?

A patient presents with lethargy, tiredness, cold intolerance, dryness of skin and hair, hoarsness of voice and weight gain. He also has psychosis and his heart rate appears to be lower than normal. Which of the following is not associated with the presenting symptoms?
Correct Answer: D
