Hello
I have gone through your question.
You have high thryoid hormons level and low or supressed
TSH level.
These results means
hyperthyroidism.
YOu didn't mention if you have symptoms of hyperthyroidism.This is an important element for the diagnosis.
If you have no symptoms of hyperthyroidism like
weight loss,irritability,insomnia,heat intolerance etc,it is necessary to repeat the thyroid tests for the confirmation of the diagnosis of hyperthyroidism.I agree with the decision of your doctor.
And if even the second thyroid test results show the same result than an thyroid
ultrasound or a
radioactive iodine uptake (RAIU) test will help to determine the cause of hyperthyroidism and than you can have the right treatement of your thyroid condition.
So, you have no reason to worry.
The tests will help your doctor to reach the right diagnosis and decide the right treatement for you(if the diagnosis of hyperthyroidism will be confirmed).
I want to say that Hyperthyroidism can be treated and resolved definitevely.So, Don't stress.
Hope this is helpful.
If you have oter question,feel free and ask.
Take care.
