More info needed: A screening test or on thyroid med? He has a normal TSH and normal free T4, so he is normal or has normal replacement results. The T-3 uptake is irrelevant. Many normal individuals have anti-thyroid antibodies. If his thyroid isn't enlarged or has no nodules, don't worry about it. If you are still concerned ask for a referral to an endocrinologist. ...Read more

Hypothyroidism : Your TSH is a substance made in the brain. When high it indicates the possibility that your thyroid gland is not able to make enough thyroid hormone. In some cases, it takes a repeat test to clarify this was not a false test, but at your age, and depending on how well or not you feel, it might indicate the need to start thyroid replacement treatment. Please review these tests with your doctor. ...Read more

Subclinical Hypothyr: Your TSH is quite high with normal t4, it suggest you have subclinical hypothyroidism, it may be due to hashimoto disease and need to check for antithyroid antibodies and need to ba treated with replacement thyroid hormone till TSH comes down to within normal range consult your doctor or an endocrinologist. ...Read more

Yes: 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, your results are normal.

I had a thyroid panel test and my results are below. Should I be taking medication? TSH - 8.070 T4, Total - 5.4 T3 Uptake Ratio - 26 FreeThyroxine-1.4

I had a thyroid panel test and my results are below. Should I be taking medication?

T4, Total - 5.4
T3 Uptake Ratio - 26
FreeThyroxine-1.4

Repeat test: Ideally, thyroid panel tests should be evaluated based on the reference range for the laboratory where the tests are performed. Most commonly, the reference range for TSH = 0.5 - 5.5. Although your TSH may be slightly high, you may not need treatment. Your total and free T4 are normal. Results such as these usually warrant retesting in 1-3 months. TSH will often return to normal without treatment. ...Read more

Great name Graves!: Overactive thyroid disease is called Graves Disease.

Tsh is .77, T3 is 112, T3 uptake 29, T4 free 1.1, T4 total 8.5 and free T4 2.5. On 100mcg of synthroid (thyroxine). Nodules and goiter, still feeling bad, why?

Felling bad: Hi. There is a tendency among patients to blame every ailment on the poor little thyroid. Your thyroid labs are a little inconsistent - you say free T4 is both 1.1 and 2.5; did you mean one is a free thyroxine index? If indicated, has your nodule been needle biopsied? Otherwise, there are a bazillion things that can make you feel bad with normal thyroid function. ...Read more

Maybe: Your TSH is abnormal it should be between 0.5 and 2.5. So you would need treatment and monitoring during pregnancy. After you deliver your doctor can figure out if you truly have low thyroid or not. Without treatment, your baby will be at a slightly higher risk of brain development issues. ...Read more

Yes: Your tests indicate you have a hypo active thyroid and should take replacement. While you may need to take this treatment for long, you need to get these repeated annually to adjust your meds. ...Read more

I have hypo last result came TSH 2.66 T3 (liothyronine) uptake 42.60 T4 total 8.22 and t7 8.75 high i had 1 i131 one year ago iodo , feeling bad?

I have hypo last result came TSH 2.66 T3 (liothyronine) uptake 42.60 T4 total 8.22 and t7 8.75 high i had 1 i131  one year ago iodo , feeling bad?

Normal levels: The t7 is a calculation based on the total T4 and t3 (liothyronine) uptake levels. The level of 8.75 is not correct. It should be 3.5 based on the numbers supplied. The TSH is the more important indicator of thyroid levels. Your TSH is normal. I am not sure what you mean by feeling bad, but it is likely unrelated to your thyroid level. ...Read more

What do these levels (tsh less than point 01, T4 3.8, T3 (liothyronine) 336) along with negative ultrasound, high uptake (rai uptake scan) with no nodules, mean?

What do these levels (tsh less than point 01, T4 3.8, T3 (liothyronine) 336) along with negative ultrasound, high uptake (rai uptake scan) with no nodules, mean?

Prob Graves Disease: Did the radioactive scan show homogenous uptake? I bet it did, since the us showed no nodules. That makes the diagnosis graves disease. Labs are consistent with hyperthyroidism. A hyper functioning nodule is not the diagnosis given the us result. Graves' disease is an immune disorder that results in overproduction of thyroid hormones. Treatment is with radioactive iodine. ...Read more

T3 (liothyronine) uptake and T4 thyroxine and free T4 index are normal, but TSH is4.65 and per the lab that is high. The highest normal is 4.5. What does this mean?

T3 (liothyronine) uptake and T4 thyroxine and free T4 index are normal, but TSH is4.65 and per the lab that is high. The highest normal is 4.5. What does this mean?

Once - Nothing!: Any symptoms? Sublinical hypothyroid or nothing. This is an odd combo of tests as T4 & FTI essential measure the same thing. Your TSH is just above normal & there is sometimes variability in the test. I would suggest, repeat testing by an endocrinologist about 2 weeks after this one, with antithyroid antibodies. If (+) closer monitoring, if (-) less close f/u. Fam Hx also important. Don't worry! ...Read more

Synthroid dose needs to increase?

It's OK: Hi. Your TSH is "normal", but I'd shoot for a value on therapy generally around the 1.0-1.5 range. The total T4, T3 (liothyronine) resin uptake, and FTI are prehistoric tests no one in the thyroid field has used for years. Your body regulates conversion of T4 to T3 (liothyronine), so your T3 (liothyronine) should be just what the body ordered. Your T3 (liothyronine) is close to the normal range; if you repeat it it's likely to be within normal range. ...Read more

Unusual combination: This is a very unusual combination of results +scan. The most likely cause(if you are not taking excess thyroid hormone and have appropriate Iodine levels in your blood) is thyroiditis, Which type would need antibody assessment and exam of the gland. ...Read more
