D. graves disease may have a heritable component. what future testing would you suggest for hayden

Hayden's blood samples at 3 months shows high thyroid levels of 22.2 μg/dL which is higher than normal range of 6-15 μg/dL. Moreover, his TSH values are on borderline on lesser side of range i.e. 0.3 μg/dL when normal range is 0.3-3.04 μg/dL. These Observations are alarming and an antibody test is highly recommended to see if hyperthyroidism is attributed to Graves disease.

Explanation:

Graves disease may have a heritable component because it is possible that any gene or genes alteration in the family tree may have inherited by the patient. It is an autoimmune disorder in which antibodies are formed against the thyroid-functioning of pituitary gland resulting into overproduction of thyroid hormones known as hyperthyroidism. The thyrotropin receptor antibody (TRAb) are produced in Graves disease which mimics the function of regulatory pituitary hormones. Physical examination is performed to see if the thyroid gland is enlarged due to overproduction of hormone. Blood samples are taken to assess the thyroid-stimulating hormone (TSH) levels which are lower than normal in blood due to high amount of thyroid hormone in circulation. The levels of thyrotropin receptor antibody (TRAb) in blood is also assessed to confirm if the cause of hyperthyroidism is none other than Graves disease.
