MON-481 Remarkable Euthyroid Hyperthyroxinemia Mistaken for Thyrotoxicosis

Euthyroid hyperthyroxinemia: a case report.

Euthyroid Hyperthyroxinemia and Euthyroid Hypothyroxinemia — Differential Diagnosis and T3-Resin Uptake

The thyroid gland is an endocrine organ that secretes the hormones triiodothyronine (T3) and thyroxine (T4), which are, in turn, under the influence of the TSH and the TRH. Though hyperand hypothyroidism remain the common clinically manifesting condition of the thyroid, in some cases, the patient remains symptomless with either excess or decrease in thyroxine levels, along with normal TSH level...

Detection of protein binding abnormalities in euthyroid hyperthyroxinemia.

This is a procedure for rapidly identifying the three common abnormalities in binding of thyroxin by protein. After incubation with [125I]thyroxin, serum proteins are separated by electrophoresis on agarose gel and binding of thyroxin to the various protein fractions is determined after autoradiography. Quantitatively abnormal binding to albumin or prealbumin and thyroxin autoantibodies is easi...
