My TSH level was 6.5 on my tests but my other thyroid tests came normal (t3 (liothyronine) and T4 I believe) what does this mean? And what could be causing this?

Several things. You have subclinical hypothyroidism. It may be asymptomatic. If you are planning pregnancy it should be treated. The cause for many women is hashimoto's thyroiditis. See a thyroidologist.
See below. T3 (liothyronine) and T4 can be normal if your protein level is high. These are total T3 (liothyronine) and T4 levels. Both hormones are transported on proteins. So, if your TSH is high, your doctor should be running a free T4 (not protein bound) to confirm that your thyroid level really is low. Otherwise, there are a few other reasons just the TSH can be high.

I am having extreme fatigue and I did blood test and my TSH level was high (8.6)! but thyroid hormones are normal (t3 (liothyronine) T4)! what is causing fatigue?

Further testing. The fatigue may be still be related to the thyroid. You should have a full thyroid panel which would include total and free T4 and t3, (liothyronine) rt3 and fti as well as thyroid autoantibodies. There can be defects in conversion from inactive to active hormone or an autoimmune process may be active. If that is the case treatment may include some hormone replacement but also addressing the immune system. Read more...

Thyroid. The TSH is only minimally elevated and that may well be simply a lab error. Your t3 (liothyronine) and T4 are near the top of the reference interval. Put this together and it is unlikely that your thyroid labs are contributing to your fatigue. Are you sleeping well? Are you overweight? You might need to have a sleep study. Please check with your primary care doctor. Read more...

What do you suggest if my thyroid tested. The results were high TSH but normal T3 (liothyronine) and t4. I also didn't test for antibodies. What could cause this?

High TSH. This suggests the thyroid is in the early stages of "failing". T4/T3 has not fallen, yet, but the pituitary TSH is working harder to stimulate the thyroid. First, repeat the TSH to make sure not lab error. Do you have hypothyroid symptoms? The cause is probably Hashimotos, even if abs negative. Talk to your doc about whether or not you need to start levothyroxine. Read more...

I'm 32 years old female. Recently I checked my thyroid and found my TSH level as 57.6 and t3, (liothyronine) T4 are normal. Please suggest.

Hypothyroidism. That TSH level is very high, consistent with hypothyroidism. It is unclear why the t3 (liothyronine) and T4 are normal with such a high tsh, so the levels should be repeated to ensure there is no lab error, and add a free t3 (liothyronine) and a free T4 to the tests, and consider adding thyroid antibodies to determine autoimmune thyroid condition.

High tsh. Those numbers indicate a condition called sub clinical hypothyroidism i.E your thyroid at risk of becoming under active. Treatment should be started. Read more...

If my reports for thyroid show normal levels of TSH and normal t3 (liothyronine). But abnormal T4 what does it show?

Thyroid issue. It's somewhat unusual to see that breakdown. Normally, we see abnormal TSH and normal t3/t4 levels. First, i would repeat the tests to make sure the new report corroborates with the old one. If the same breakdown is seen this may mean your thyroid is hyperfunctioning. In this case, i refer patients for radioactive iodine uptake study to confirm or rule this out. Read more...
