Normal Tsh Levels After Thyroidectomy
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 moreSee 1 more doctor answer
Does a low T3 (liothyronine) uptake with normal TSH and ft4 indicate adrenal insufficiency? Also had a borderline low am cortisol. On levo for total thyroidectomy.
I had a total thyroidectomy due to cancer. My lab shows low tsh but t4 and t3 (liothyronine) levels are normal indicating correct dosage why would my tsh be low?
I'm taking 150mg of levothyroxine after total thyroidectomy & RAI a month ago due to papillary thyroid cancer. My TSH level is 0.091uIU/mL. Is it normal?
On who you ask. Most lab reports show normal as being 0.5 - 5 mlu/l, but many people feel the range should be 0.3 - 3. If you are being treated for hypothyroidism, the ideal range is 1 -2. I usually start to take notice when someone's TSH is >2.5.

Definitely: TSH is a very poor marker for tissue hypothyroidism and to assess Hashimoto's. you can even have normal TPO and thyroglobulin antibodies and manifest Hashimoto's. Get your free T4, free T3, (liothyronine) Reverse T3, (liothyronine) and antibodies checked and optimized... refer to https://www. Facebook.

It's controversial: There is broad consensus that a TSH between 0.3-2.5 is normal (assuming no pituitary problem exists), and broad consensus that TSH levels above 10 are abnormal and should be treated. A middle-of-the-road approach might be to say that levels between 5-10 are abnormal, and treatment is likely to be beneficial, and that values between 2.5-5 may be abnormal, and that treatment may be beneficial. ...Read more
Normal ranges vary from lab to lab and you should check the reference range for your lab. General ranges are given below:
tsh: 0.4 - 4.0 miu/l
t4: 4.5 – 12.5 for more info see the site below

Very slightly low: Your TSH is very slightly low, which can be seen for a variety of reasons. No need to worry unless it's still low when you repeat it. Tsh is secreted in spurts and you never make big decisions based on just one result. ...Read more
My T3 (liothyronine) and T4 levels are normal, TSH is 7.76 inspire of taking thyronorm 50mg everyday, please advise?
Higher dose: Tsh is more sensitive than T3 (liothyronine) or T4 levels for identifying patients whose thyroid levels are abnormal for them. A high TSH means that your pituitary gland is trying to get your thyroid to make more thyroid hormone. Since your thyroid can't (or you wouldn't be on thyroid hormone), you probably need a stronger thyroid tablet. Talk to your doc to make sure you're getting the most from your pills. ...Read more
Yes: Thyroid levels does not take into account the peripheral conversion of t4-t3 sometimes T3 (liothyronine) at tissue level would be low. I found environmental pollution and increased plastic usage thyroid requirements are higher. People who has muscle issues - myopathy has higher thyroid need. ...Read more
I had 2 nodules that were being monitored for the past 5 yrs but in the last yr they have grown and joined. I have normal TSH level. Should I worry?
More info needed: Certain features on the ultrasound can clue you in on whether or not a nodule should be biopsied. In general, nodules that are growing over time should be evaluated with an ultrasound guided biopsy. Tsh are usually normal in patient with thyroid nodules and does not help ruling in or out thyroid cancer. ...Read moreSee 1 more doctor answer
Tsh levels are these normal? Tsh- 3rd generation- 1.04 miu/l, then another one was 0.63 miu/l. Tsh w/free T4 rfx 1.50 miu/l. Are these normal levels?
Probably: Most labs include a reference range (or normal range) in their reports. While there can be some variation from one lab to another, almost all labs would consider TSH values between 0.5 to 3.0 to be normal. All three of your levels fall in this range, and so would be considered normal. ...Read more
