Question 1

i have a tsh level of 0.05 but my t3 and t4 is normal. what is my problem?

Accepted Answer

Low  tsh: A tsh of0.05 is very low and is consistent with hyperthyroidism in which case the t4 and t3 would be elevated. A tsh of 0.5 would be within normal limits. In  cases of subclinical hyperthyroidism the tsh is low and the t4 and t3 are normal, as in your case. I recommend rechecking your tsh to be sure.  A thyroidologist or endocrinologist is best to evaluate your situation if your tsh is still low.

Question 2

my t3 levels have been low consistently, tsh normal, t4 on the high end of normal. is the low t3 anything to be concerned about?

Accepted Answer

Hypothyroid and T3: If the TSH is normal, then that is strong evidence that you are normal.  Pituitary TSH responds mostly to T3.  If you T3 were too low, the TSH should be high.  Indeed, I am not sure why T3 is being measured.  There are more problems with the T3 assay than that of T4. This could just be "lab error".

Question 3

i have a tsh level of 5.69 and just found out that my t4 level is 1.1. what does this mean? if my t3+t4 is normal then what could be the problem?

Accepted Answer

Check antibodies: Ask your doctor for a test called thyroid peroxidase antibodies. If it's high or positive, then you have autoimmune thyroid disease and will need thyroid replacement in the future, if not now depending on how you feel.

Question 4

my tsh level was high 17, t3 and t4 level were low before 8 months ago. i didn't use any medications. now my tsh is 1.8, and t3 and t4 are normal . why it happen ? is it possible ?

Accepted Answer

It is possible.: If your diet changed meaning that you got  iodine  or more iodine in your diet through the food or salt you eat.

Question 5

what are the normal levels for tsh, t4 and t3 (liothyronine) for a young man?

Accepted Answer

Some controversy: Most labs use the reference range of 0.5 - 4.70 or 5.0 miu/l for "normal". However, the american association of clinical endocrinologists (hormone specialists) recommends a narrower range: 0.3 - 3.0 your doc can advise you which reference range s/he follows. T3 (liothyronine) (total): 80-200 ng/dl; T4 (total): 4.5-12.5 µg (micrograms)/dl; T4 (free): 0.8-1.8 ng/l.

Question 6

is tsh levels of 0.03 a lot to worry about. my t3 (liothyronine) and  t4 are normal.?

Accepted Answer

It depends: Are you taking thyroid medication? On any other meds?
Why was this test done?
Have you been told a bout having a thyroid disease? The TSH level in your case is low....Suggesting a possible hyperactive thyroid state..
This could be a lab error as well.
Would check with your doc..

Question 7

how do i increase my free t4 levels. my tsh is 1.029. my free t3 is 2.8. my free t4 is 0.9?

Accepted Answer

: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your TSH and free T4 are in the normal range and no intervention is needed.    Wish you good health!

Question 8

my tsh 3rd generation level came back at 9.490. my t4 was normal and t3 (liothyronine) was low.taking 200 mcg. what do these numbers mean?

Accepted Answer

Still hypothyroid: Not sure how long u have been on thyroid replacement, but if been on 200mcg daily over 6-8 weeks, likely require increase dose. If u have just had u'r medication adjusted the. Repeat TSH usually done in 6 wks; the numbers show that u'r body is still in hypothyroid state and that u'r thyroid gland is making less and less hormone or the T4 is not being converted to T3, (liothyronine) so thyroid medicine needed

Question 9

i guess my t3 (liothyronine) and t4 levels are normal but tsh is high.my weights increasins n i also have polycistric ovaties....what should i do...?

Accepted Answer

Go see your doc: You need to increase your thyroid medication.  High TSH is sensitive for low thyroid. 
Good luck.

Question 10

my t3 (liothyronine) and t4 levels are normal, tsh is 7.76 inspire of taking thyronorm 50mg everyday, please advise?

Accepted Answer

Higher dose: Tsh is more sensitive than T3 (liothyronine) or T4 levels for identifying patients whose thyroid levels are abnormal for them.  A high TSH means that your pituitary gland is trying to get your thyroid to make more thyroid hormone.  Since your thyroid can't (or you wouldn't be on thyroid hormone), you probably need a stronger thyroid tablet.  Talk to your doc to make sure you're getting the most from your pills.
