"Normal": I suspect "medium range" means normal. You really should discuss the results of tests with the doctor who ordered them since there may be particulars in your case so that "normal" is not normal. ...Read more

Not everyone has tremor, palpitations, anxiety, emotional lability, weakness, heat intolerance, increased perspiration, and/or weight loss. But your testing does suggest that you need further evaluation for the cause of your hyperthyroidism. ...Read more

I'm just wondering, if you have thyroid cancer will your TSH level in your blood test be off?

I'm just wondering, if you have thyroid cancer will your TSH level in your blood test be off?

Not necessarily: Tsh stands for thyroid stimulating hormone. It does exactly that-- tells your thyroid to make thyroid hormone. If your thyroid isn't making enough hormone, your TSH will increase. And if your thyroid is making too much hormone, your TSH will go down. But cancer is usually not the cause for a high or low tsh. And you can have a completely normal TSH and still have thyroid cancer. Hope that helps! ...Read more

I had a us of my thyroid and they found a hypoechoic nodule measuring 0.413 x 0.546cm. Blood test came back normal TSH and free T4 really nervous. ?

Please don't worry: One of the next steps is usually a fine needle aspiration biopsy, which involves using a very skinny needle to remove cells from the nodule. In my experience, most of these cells are benign, especially give the size of your nodule. However, if they are malignant or suspicious, you will need thyroid surgery. Most thyroid cancer (papillary type) can be cured. ...Read more

Could be both: The symptoms could be from both. I would treat to bring the thyroid to normal. If the symptoms are still there, then it's most likely not the thyroid causing the original symptoms. Get your thyroid antibodies check as well. ...Read more

Thyroid blood test: normal tsh, and normal t 4, slightly lower free t3 (liothyronine). What is a normal TSH level?

Thyroid blood test: normal tsh, and normal t 4, slightly lower free t3 (liothyronine). What is a normal TSH level?

0.4-4.5: In most labs, the normal TSH ranges between 0.4 and 4.5. Most people have TSH levels under 2.5. One can still be normal with higher TSH levels, but if you have hypothyroid symptoms, a mildly high TSH could be a sign of developing hypothyroidism. Free T3 (liothyronine) levels are not accurate in many labs, so a slightly low level may be meaningless. You should see an endocrinologist if you have symptoms. ...Read more
