Thyroid Function Tests (TFTs) are among the most commontly ordered tests. Significant overuse of TFTs can occur when instead of using a single TSH test to screen for thyroid disease a full panel (TSH plus FT4 and FT3) is ordered. The aim of our study was to evaluate the effectiveness of the application of a scientifically-established laboratory-controlled algorithm for TFTs to physician's orders for inpatients and to address potential pitfalls of such an approach.
