My TSH 17.38, ft4 15.72 and ft3 4.25 what does it means?

Would be rare: It could make sense if your TSH was elevated due to pituitary or hypothalamic tumor. This is very unlikley. Would repeat labs. You need to include normal range as they vary from lab to lab. Looks like your ft4 and ft3 are both upper limit of normal. Usually would suppress tsh. ...Read more

I have a TSH redsult of 17.38, ft4 15.72 and ft3 4.25. Is it normal or dangerous?

You are not taking: Tsh is very sensitive to the compliance of you taking the thyroid medication. Usually, when we see a high TSH and a high t4, it means the patient took some extra thyroid meds recently. Your overall control is bad. Just take your thyroid medication regularly at the same dose and re-do the labs in a 6 weeks. Tsh level is really the long-term ft4 sensor! ...Read more

60yo, tested today: TSH (6.8 last month) went up to 10.51 and FT4 is 11.71. Why did it go up and can I wait 3 mnths to start any meds as I'm busy now?

Doesn't add up: Your TSH doesn't correlate with your FT4, Are you sure your Ft4 is 11.7? This is too high, look at the blood report one more time and let me know. Your TSH is high and if it's 10 and your Ft4 is within normal range (0.8-2.5) and you are symptom free then you have subclinical Hypothyrodism and it's time for treatment. Usually elevated TSH and Ft4 are lab error, or very rare medical conditions. ...Read more

Thyroid: Numbers alone aren't enough to work with. Do you have hypothyroidism or thyroiditis, or post thyroidectomy or none of above. Based on ft3 and ft4, i would expect your TSH to be lower. It depends on your clinical picture, lots of variables influence these #s, incl. Meds, other disorders, hormones , etc.Do you take thyroid meds? ...Read more

My TSH reamains so low (0.02) after RAI (3 years ago) even if FT4 and FT3 are normal? Does this have anything to do with the rest of my symptoms.

My TSH reamains so low (0.02) after RAI (3 years ago) even if FT4 and FT3 are normal? Does this have anything to do with the rest of my symptoms.

It depends: It depends what your symptoms are. Generally, if your TSH is low but your T4/T3 are normal then you should not worry. If you are feeling ok, then this an even better indicator. Graves disease may manifest with a low TSH but it is more important to go by your T4/T3. ...Read more
