Abstract

The presence of a T4-binding autoantibody resulted in a falsely high value for free T4 and a falsely low one for total T4 in a patient who was clinically euthyroid. Values for serum T3 and thyrotropin were normal. Such results should alert the analyst to the possibility that the patient's serum contains autoantibodies.
