Question 1

is single solid thyroid nodule more/less likely to be malignant in presence of just-id'd suppressed tsh, slightly elevated free t3/free t4, tsi of 313?

Accepted Answer

More likely, but: A solid single nodule in a 58 year old woman is more worrisome than multiple nodules or a single cystic nodule. Thyroid tumors are seldom functional. The best thing for you to do is to have a fine needle aspiration. The interpretation of the fna will allow for a determination of what to do next. Good luck.

Question 2

t4 is elevated. 14.4  but free t4 and free t3 normal, tsh normal, antithroglobulin ab is 14, normal range 0-115?

Accepted Answer

See below: 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. Having said that, if free T4 and T3 and TSH are normal, there is no cause for concern. T4 may be elevated in women on birth control pills.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. 
Practice safe sex, if you have sex.

Question 3

free t3 (liothyronine) 3.2 range 2.3-4.2, free t4 1.4 range0.8-1.8  but tsh elevated 8.2 what does it mean and do i need medication

Accepted Answer

Controversial topic: Elevated TSH in presence of normal free T4 & free T3 (liothyronine) is known as subclinical hypothyroidism in traditional medicine (http://jama.Jamanetwork.Com/article.Aspx?Articleid=186627 & http://www.Uptodate.Com/contents/subclinical-hypothyroidism). Some feel strongly this should be treated (http://jcem.Endojournals.Org/content/86/10/4585.Full). Important question to ask is how you feel: treat if symptomatic.

Question 4

i have a normal tsh and free t3 (liothyronine) but elevated free t4. what does this mean?

Accepted Answer

Probably nothing: Are you taking thyroid replacement? A normal TSH usually means all is ok. See a thyroidologist.

Question 5

normal free t3/free t4. elevated tsh (5.50). hypothyroidism??

Accepted Answer

Yes or No: No, if the patient has no symptoms and is a normal person with a normal thyroid gland. Yes, if the person's thyroid gland is actually working overtime to maintain adequate levels of thyroid hormones. The question is not merely what to call it, but more about whether or not the thyroid gland is working overtime and whether or not to supplement with thyroid pills to let the thyroid gland rest a bit.

Question 6

free t3 (liothyronine) high, thyroid peroxidase ab greater than 1000, thyroglobulin ab elevated but tsh ultrasensitive normal as well as thyroglobulin. ?

Accepted Answer

Autoimmune thyroid: All this says is you have hashimoto's thyroid disease.  Nothing else specific.  Are you taking thyroid medication? What kind?

Question 7

my sons tsh is normal 1.04 but he has mildly elevated total t3 and t4, 230 and 14.1 respectively he is 8 years old.does he have euthyroid hyperthyroxinemia? what should be done? should we check free t3 t4? has no symptoms or weight loss?

Accepted Answer

: What was the reason he have thyroid panel checked at 8 years old? The normal range of TSH for children varies a lot by different laboratories in the world. Was his TSH reportedly in normal range? Normal TSH level rules out thyroid dysfunction provided there is no problem with pituitary gland.

Question 8

do i need  treatment if my tsh 7.69 high normal  free t4 and free t3 (liothyronine) and elevated thyroid antibodies?

Accepted Answer

Yes: Tsh 7.69 with high tpo is not "high normal" but high and indicates hypothyroidism. Having high tpo indicates autoimmune or hashimoto's thyroiditis. I suggest adding selenium zinc b complex and vitamin c and iodine and avoiding gluten for a month and  rechecking levels in a month. If no change then you might need thyroid supplementation.

Question 9

why does some doctors consider a free t3/rt3 ratio valid and others don't?

Accepted Answer

Valid for what?: If you are chronically ill, the ratio of t3 (liothyronine)/rt3 (liothyronine) decreases. In patients with kidney failure, other chronic diseases this is called "euthyroid sick syndrome". Emphasis "euthyroid", i.e. Normal.  Even if t3 (liothyronine) is low, you don't treat this with thyroid, you treat the underlying condition.  I rarely measure rt3 (liothyronine) because it does not tell me anything that is not evident.

Question 10

what is the definition or description of: free t3 (liothyronine)?

Accepted Answer

Thyroid hormone: Thyroid hormone exists in 2 states T4 and T3 (liothyronine) ( they differ in how many iodine molecules are bound to the thyroid hormone chemical structure, with T4 having 4 and T3 (liothyronine) having 3 iodine molecules) ordinarily the thyroid hormones float in the blood either chemically attached to a protein ( protein- bound) or not ( free) so free T3 (liothyronine) is the amount of T3 (liothyronine) hormone in the blood not stuck to protein).
