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
What does a low T4 index (T7) indicate?
My Free T4 is .9ng/dL and my T3 uptake is 32%
My calculations give me a T4 index of .33, internet search
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
I just received lab results showing the following: thyroid
tsh 15.060 high thyroxine (t4) 6.2 t3 uptake 26 free thyroxine index l.6?
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

I got a thyroid test and need analysis of the results
Thyroxine t4 = 6.8
T3 uptake = 26
Free thyroxine index = 1.8?
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.
Practice safe sex, if you have sex. ...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
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. We need to know the normal limits of the lab that you were using but for the most part these tests may be fine although the T4 may be a little high but I need to know the range for your lab. Are you really name Graves? ...Read more
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

If my TSH and T4 are high and free thyroxine is normal...but T3 (liothyronine) uptake is low, should I take synthroid my dr prescribed?
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
TSH is always very low T3 (liothyronine) is normal high T4 is normal low. **Uptake scan, 5.3, showed hypothyroidism! All other tests Ok Pituitary ok different DX's?
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
TSH 2.534 (ref 0.340-5.600), T3 (liothyronine) uptake 45.7 (ref 32-48), total T4 13.37 (ref 6.9-12.2), free T4 6.1 (ref 1.1 – 4.6). No symptoms, is this high T4 OK?
Ok.: Have the test repeated if you are in doubt. May be a lab errror since TSH is normal. ...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?
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?
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

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's likely to be within normal range. ...Read more
Normal T3 (3.53) and T4 (1.42), very low TSH (0.02), thyrogobulin is 69, thyroid uptake imagining "significantly abnormal and below normal range"...
Low T3 (liothyronine) uptake (21%), Normal TSH (3.190), normal T4 (9.4), normal free thyroxine index (2.0). Also, low BUN/creatine ratio (7). Is this normal?
YES: T-3 Uptake not a reliable test....the rest of your thyroid tests are normal and your kidney function is as well! ...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 the time.
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?
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

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

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
