T4-7.7, T3 Uptake 7.7, TSH 1.41 is this normal??

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. You may consult this site for more information on this topic.

I got a thyroid test and need analysis of the results Thyroxine t4 = 6.8 T3 uptake = 26 Free thyroxine index = 1.8?

I got a thyroid test and need analysis of the results Thyroxine t4 = 6.8 T3 uptake = 26 Free thyroxine index = 1.8?

Okay: 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 T4 level is normal. However, it would have been useful to have TSH level.
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.

Tsh level is 9.23 HIGH (0.450-4.500) Thyroxine T4 6.4 (4.5-12) T3 uptake 27 (24-39%). free thyroxine index 1.7 what does it mean?

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

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

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? TSH - 8.070 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

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

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

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

See your doctor: If you are having issues with sleep and a fast pulse, you should see your family practice physician. Think of TSH like a flagpole. If it is high, you may need more thyroid hormone. If it is low, you may need less thyroid hormone. ...Read more

I have a T3 (liothyronine) uptake of 30, a T4 total of 11.3 and an FTI of 3.4. What does that mean? I'm also tired all of the time.

Tired: If those numbers are correct that is not the cause of your tiredness.
That said, labs occasionally misread the patient's name on the blood specimen.
Either way, please get in touch with your primary doctor as soon as you can. ...Read more

My t4 is 5.80 my T3 (liothyronine) uptake is 37.8 my FT4 INDEX is 2.2 my tsh 3rd generation is 97.352 I was put on meds 75mcg I need to know what this means help?

Hypothyroid: Both the T3 (liothyronine) uptake and FT4 Index are indirect evaluations of thyroid hormone levels.
Briefly, the total T4 is a reservoir for active hormone (T3 (liothyronine)). If the body senses low T4 or T3 (liothyronine), then it secretes TSH to tell the thyroid gland to make more hormone.
Your TSH being 97 (normal ...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?

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 is the significance of a low T3 (liothyronine) uptake with normal TSH and ft4 7 weeks post total thyroidectomy and on levothyroxine for 7 wks?

What is the significance of a low T3 (liothyronine) uptake with normal TSH and ft4 7 weeks post total thyroidectomy and on levothyroxine for 7 wks?

No significance: T3 (liothyronine) uptake is an old test used to indirectly measure t4. Now that we have assay to accurate measure free t4, we don't use this test anymore. If your TSH and free T4 is normal on levothyroxine, then you are doing fine on the current dose. No need to change anything at this point. ...Read more

Thyroidologist: Your thyroid parameters are within normal range except for borderline low tsh which may indicate subclinical hyperthyroidism. Are you taking any thyroid supplements? Are you symptomatic with weight loss, tremor, heat intolerance, thyroid nodules? An endocrinologist or thyroidologist is best qualified to evaluate, advise, follow-up and treat you if needed. ...Read more

Thyroid tests: All else being equal it means your dose of levothyroxine is probably too high. The TSH level is very low, meaning your body is trying to reduce thyroid hormone levels. Follow-up with your doctor to discuss. ...Read more

Person with normal Total T4, T3 (liothyronine) Uptake, FTI, Ultrasensitive TSH but LOW Total T3 (liothyronine) (63.55 ng/dl) = 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

Not your thyroid: I can't say if you needed to be started on T4 without seeing your test results before treatment but your current tests show normal thyroid levels on your current dose. It is rare for an underactive thyroid to case weight gain and when it does, the thyroid is severely underactive and weight gain is no more than 5-10 lb. So your 40 lb weight gain is likely due to lifestyle not hormonal issues ...Read more

My thyroid uptake was high. I feel terrible. Should I consider ablation of the thyroid? My TSH is low normal and my T3 (liothyronine) andt4 are high normal. Help!

Yes/drugs/surgery.: You apparently have a serious issue with your thyroid. Although your lab values are not evident, the fact that you feel bad is enough to see your doctor for urgent treatment. One option is ablation of a nodule, not your whole thyroid, by radioiodine. Another is surgery. If you have high hormone levels, drugs like ptu (propylthiouracil) & DEXA and potass-iodode are needed. Again see your doctor asap for work-up. ...Read more
