      Persons with hyperthyroidism absorb too much iodine. A thyroid scan producing images is typically conducted in connection with the uptake test to allow visual examination of the over-functioning gland. Thyroid scintigraphy is a useful test to characterize (distinguish between causes of) hyperthyroidism, and this entity from thyroiditis.

      Hyperthyroidism is treated mostly by medical means, but occasionally it may require the surgical removal of the thyroid gland. If there is a lump of the thyroid or a diffused enlargement (goiter), your doctor will propose a treatment plan based on the examination and your test results.

      Thyroid storm, also called accelerated hyperthyroidism or thyrotoxic crisis, is defined as a sudden life-threatening exacerbation of thyrotoxicosis associated with systemic decompensation.[1,3] Hyperthyroidism and thyroid storm are caused by excess synthesis and release of thyroid hormones resulting in both high free and total T3 and T4 levels ...

      If the serum TSH is lower than 0.1 uU/ml, plasma free T4 and T3 should be measured. If the serum TSH is low, and free T4 and T3 are high, the diagnosis of hyperthyroidism is confirmed, and a 24-hour thyroid radioiodine uptake scan can be ordered to differentiate Grave’ hyperthyroidism from other causes (see p. 461, Lancet article).
