Tests for diagnosing Graves’ Disease

Reading time: 1 min

Diagnosis is based on the symptoms of hyperthyroidism and effects on the eyes, as well as imaging and analytical tests. 

Blood collection tube

Blood tests. Blood tests show a high level of active thyroid hormones: high levels of free thyroxine (T4L) and free triiodothyronine (T3L) in the presence of low levels of thyrotropin (TSH) regulatory hormone. The cause of GBD is confirmed by the presence of typical activating antibodies, known as anti-TSH receptor antibodies (anti-TRAb, LATS, TSI), which determine the activation of thyroid cells and hyperthyroidism.  

Gammagrafía tiroidea

Imaging tests. An ultrasound is used to rule out nodules and scintigraphy is used for other forms of thyroiditis. The ultrasound shows a large, highly vascularised thyroid, usually with no nodules. Scintigraphy shows diffuse enlargement of the thyroid.
