Abstract

Non-thyroidal illness (NTI) is frequently characterized by triiodothyronemia (low T3) and abnormal thyroid function tests. This could result in an incorrect diagnosis of hypothyroidism. The purpose of this study was to determine which thyroid function test or group of tests could be used to identify those euthyroid patients with NTI. A total of seventy patients with triiodothyronemia were clinically evaluated and tested for: total T4 , normalized T4, "free'' T4, total T3, reverse T3 , T3 uptake, free thyroxine index, and TSH. Commercially available radioassay kits were used in testing. The patients were separated into four groups: primary hypothyroid, secondary hypothyroid, hypothyroid with NTI, and euthyroid with NTI. The results correctly identified the primary and secondary hypothyroid patients and those hypothyroid patients with NTI. The normalized T4 test accurately identified those euthyroid patients with NTI and triiodothyronemia 94 percent of the time.
