Re: 17 year old lab results--Please reply
His doctor is concerned about his TSH. That's why he is offering the thyroxine. It is the standard treatment for hypothyroidism. So yes, he does have a thyroid disorder and he should accept and use the thyroid hormone being offered.
I can't comment on the antibodies without knowing the lab's reference range for the test. If the result is elevated, it means the cause of the hypoT is due to the autoimmune disease called Hashimoto's thyroiditis. Further proof that the elevated TSH shows hypoT.
I can't say if correction of the hypoT will definitely result in growth, because I'm not familiar enough with all the variables of growth retardation. But, thyroid treatment does have the potential to allow growth if the bone growth plates have not yet closed.
