Question 1

i have a high tsh but normal t4 levels, what does this mean?

Accepted Answer

Hypothyroidism: The TSH test is10 times more sensitive for the diagnosis of hypothyroidism that the t4. The TSH is reported on a log scale so that small changes in the TSH value are caused by relatively big changes in the blood level. This is a reflection of the pituitary being extremely sensitive to change in the T3 (liothyronine) level  if you have symptoms it would be wise to seek treatment.

Question 2

high tsh levels but normal t4 levels, i don't understand what this means?

Accepted Answer

Early hypothyroidism: If the elevated TSH persists, it generally indicates early hypothyroidism, which can easily be diagnosed and treated by your doctor.

Question 3

33 yr m 6'2 185 pounds. high tsh levels but normal free t4, whst exactly does this mean?

Accepted Answer

Euthyroid sick: Euthyroid sick syndrome is a condition which can occur due to abnormal TSH level, with normal free T3, (liothyronine) and T4 levels or normal TSH level, with low free T-3, free T4 levels. Causes of elevated TSH, with normal free T3, (liothyronine) free T4 levels can also be due to secondary acquired hypothyroidism, including autoimmune thyroiditis.  Consult your physician for further evaluation and treatment is recommended.

Question 4

can a high tsh level but normal t4 cause hypothyroid symptoms or not?

Accepted Answer

Maybe: Your symptoms may be from subtle hypothyroidism. Although your T4 is in the normal range, it may be lower than it was. Some people are sensitive to minor variations in t4. On the other hand, the symptoms of hypothyroid can be due to other things. Once you get treated with levothyroxine, you will know.

Question 5

pheochromocytoma could it be detremined by the tsh and the free t4 ? and if it can should they be low or high?  tsh is 0.6 and the free t4 is 3.2

Accepted Answer

Pheo: Pheo is not diagnosed by TSH levels. It is a clinical  suspicion  based on high blood pressure and other symptoms. Certain urine tests are diagnostic.

Question 6

what does it mean if i have high tsh, t3, (liothyronine) t4 levels?

Accepted Answer

HiTSH=hypo,hiT4 hype: Thyroid function is measured many ways.  The TSH is your body's call for more hormone, so a high TSH suggests underactive thyroid, very low TSH overactive. The t4/t3 levels are measures of circulating hormone, so high T4 or T3 (liothyronine) suggest hyperthyroidism and vice versa.  T4 levels can beaffected by hormones and so need to be interpreted carefully.  For initial testing, the TSH alone best test.

Question 7

im 42 type2 diabates for 10 yrs (avg 180 sugar level), recent lab test shows high tsh:11.5 (range 0.3-4.2) but normal free t4: 19 (ref12-22), vit d 11.3

Accepted Answer

Lab error?: The TSH is elevated, but the free T4 is in the upper range of normal.  One can have subclinical hypothyroidism where the TSH level is high, with normal free t4, though usually the free T4 is in the low range of normal.  You should have the test repeated after 1 month.  Your vitamin d level looks low, you should take a vit d supplement of around 2000 iu daily.

Question 8

my thyroid panel shows low t3 (liothyronine)  (29), normal t4 (8.10) and high tsh  3.16. what does this mean

Accepted Answer

TSH normal: Your TSH is normal and your thyroid appears to be functioning properly. Ignore the "t3" as it's not a real measurement of T3 (liothyronine) level.

Question 9

total thyroidectomy 4 mo ago. high tsh & t4, low t3 (liothyronine). feeling very hypo. increases in levothyroxine not helping symptoms. sliding downhill fast! help!

Accepted Answer

Thyroid: Something does not sound right.
A high TSH with a high T4 is very uncommon.
It is possible, but unlikely that your pituitary gland is producing too much TSH.
You need to see your thyroid surgeon or your regular doctor as soon as possible.

Question 10

what does this mean?t3 (liothyronine) free normal, tsh normal, t4 categories-t4 high, t3u low, fti high.tsh tested again 6 months later, lower but normal.on nuvaring only

Accepted Answer

Normal thyroid tests: Normal TSH level indicates normal thyroid function in the majority of cases. Normal free t3 (liothyronine) and normal freet4 usually support the fact. Total T4 (t4) can be high without excess thyroid when the thyroxine binding globulin (tbg), a thyroid hormone carrier, is elevated, as in pregnancy and while taking a bcp. Then t3 (liothyronine) (resin) uptake (t3 (liothyronine)u) is low and fti normal (tests now outdated should not be checked.
