euthyroid status and negative TRAb. The only laboratory basis for diagnosing our patient as having Graves' disease was his elevated TSAb level.
Subtyping was based on measurement of TRAb in serum (TRAb+ patients were classified as Graves' disease), and no other cause for the hyperthyroidism was identified.
A number of authors have found a positive correlation between the levels of TRAb and the presence or severity of GO (4,6,17-21).

The patient has not received antithyroid therapy for more than four years although TSAb, TRAb and anti-thyroglobulin antibody levels continue to be abnormal.

Detection of TRAb has become the most commonly used method to differentiate the etiology of thyrotoxicosis when RAI uptake is unavailable or contraindicated [3].
The majority of TRAb assays detect both TSI and TBAb.
