Question 1

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?

Accepted Answer

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.

Question 2

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?

Accepted Answer

Low TSH: Low TSH should be respected and you may need adjustment of your medication. Seeing your Endocrinologist may be needed, and they can discuss if a dose change is needed. T3, (liothyronine) T4 don't always paint the full picture and have to looked in context of your symptoms, TSH.

Question 3

im 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?

Accepted Answer

Seems suppressed: Discuss with your MD if reduction of dose of levothyroxine is indicated

Question 4

anyone know what is a normal tsh level?

Accepted Answer

May vary by lab: The normal values of a TSH may vary a little by testing lab, but generally 0.4-4. The levels change for children.

Question 5

what are the normal tsh levels for a teenager?

Accepted Answer

TSH: It depends on the assay.  Generally 0.5-5.0.

Question 6

what is the normal tsh level for an average male?

Accepted Answer

Depends: 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.  
See http://www.Nlm.Nih.Gov/medlineplus/ency/article/003684.Htm.

Question 7

hashimotos disease with normal tsh levels, is that possible?

Accepted Answer

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.com/groups/95847031171/

Question 8

what are normal tsh levels?

Accepted Answer

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.

Question 9

can you have hashimotos and a normal tsh level?

Accepted Answer

Yes.: The TSH level rises when a significant loss of thyroid cells are lost due to inflammation.  In an early stage this is less likely to be present.

Question 10

should i be concerned of a high tsh level with a normal  tsh  4  level?

Accepted Answer

I assume you mean a: high TSH with a normal T-4???
That is usually indicative of very early (subclinical) hypOthyroidism (LOW thyroid) 
If the gland is NORMAL size (not enlarged) your Doctor may wish to just follow this finding..
Hope this is helpful!
