      Despite the proliferation of thyroid function tests, just three tests, free-T4 index, free-T3 index, and TSH, suffice for the evaluation of the thyroid status of all but a very few patients. In the form of an algorithm the authors outline a logical sequence for the development and interpretation of thyroid function tests that prompts the clinician to integrate the results with clinical assessment.
