Abstract
PDF - Antithyroid hormone autoantibodies can be present in the sera of patients with thyroid and non-thyroid disorders. Antithyroid hormone autoantibodies in a patient's serum interfere with radioimmunoassay of thyroid hormones. Clinically, this interference can result in discordance between the serum thyroid hormone levels and the clinical features of the patient, which can lead to misdiagnosis or inappropriate treatment. We experienced a woman who had primary hypothyroidism with unexpectedly high concentrations of serum total triiodothyronine (T(3)) and free T(3), and she had been treated for Graves' disease in the past. Through the use of a polyethylene glycol precipitation method, we detected the anti-triiodothyronine autoantibodies in her serum. We report on this case along with a review of the related literature.

Abstract
PDF
- Autoantibodies against thyroid hormones can be detected in the sera of patients with both thyroidal and non-thyroidal disorders. These antibodies interfere with the radioimmunoassay of serum total and free thyroid hormone concentrations, resulting in a discrepancy between the measured hormone levels and clinical features. This can in turn lead to an erroneous diagnosis and patients may receive unnecessary treatment from physicians who are unaware of the presence of the autoantibodies. We experienced a woman having Hashimotos' thyroiditis with a spurious elevation of total T3 and free T3 values according to one-step analog-tracer radioimmunoassay who was had been treated as Graves' disease in past. Through the use of a polyethylene glycol precipitation method, she was subsequently revealed to have anti-triiodothyronine autoantibodies. We report this case with a review of related literature.
