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.

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

Can you help interpret these lab test results? I have a family history of Hashimoto's Disease: T4 total 8.6 TSH. 762 mIU/L and a t3 (liothyronine) uptake of 33%
Thyroid tests: The units of the t4 test and the lab range matter. If mcg. Dl, your tests look to be in normal range. Usually, TSH, free t4, free t3 (liothyronine) are tested. It also helps to know what medications a patient is taking that could affect levels of thyroxine and whether a patient is pregnant. If a + fam history of Hashimoto's, autoimmune antibodies ATA, TPO may be present. ...Read more

0.024 TSH, Normal T3 (liothyronine) and T4, postive antibodies, depressed iodine uptake test. Please interpret results? Confused and not getting answers..
Thyroid tests result: If you have normal output of thyroid hormone (T3, T4) from your thyroid gland then the level of the thyroid stimulating hormone (TSH) should be low, which it is! I'm not sure why your doc ran a thyroid uptake test because you say you have normal thyroid hormone output. Ask the doc for the reason for doing a test. It should always be a good reason that you should understand. ...Read more
I am on levothyroxin 88mcg. But dr wants me to do the uptake scan, is this just for hyper or also hypo? Was told my T4 was high from last weeks blood
Thyroid scan: I use it for hyperthyroidism diagnosis. Not sure the rationale for this test in your case. If you are on thyroid supplement and your T4 is high, I would lower it and recheck in 6 weeks. If normal, i'd not do the scan. I cannot comment on your doc's decision since I don't know the full story. ...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.
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

Just took i123 this morning, no restrictions. I go bak in the morning for uptake scan. Tsh 0.17 T4 1.6 thyroglobulin <20 antibodies 16 some clarity.?
Thyroid scan: It is hard to tell from your question and bio what your doctor is thinking. The scan will 1. Measure uptake. High uptake is consistent with hyperthyroidism, eg graves disease. 2. Give an image. Diffuse uptake (i.e. All over) suggests graves. Patchy could be a nodular goiter, or hashimotos. Have you been hyperthyroid? Talk to your endocrinologist. ...Read more
Have 1.1 cm Node on lower pole right lobe. TSH=1.28 T4=8.4 Free t4=0.93 I-123 24h uptake = 41.8% having FNA Wed. What are your thoughts on this?
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
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

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

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
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
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
Hi, t3 (liothyronine) uptake: 32, t4 free 1.35, t4 11.8, FTI 3.8, TSH 2.050, im taking. 50 mcg levothyroxine. How's my thyroid, gain 40 pounds last few years?
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
