What are normal TSH levels?

Normal TSH Levels. Run between 0.5-5 mIU/L. Remember that TSH is opposite what you would normally think. Low TSH levels mean that you are HYPERthyroid. High TSH levels mean that you are HYPOthyroid. Hope this helps!
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.

Thyroid blood test: normal tsh, and normal t 4, slightly lower free t3 (liothyronine). What is a normal TSH level?

0.4-4.5. In most labs, the normal TSH ranges between 0.4 and 4.5. Most people have TSH levels under 2.5. One can still be normal with higher TSH levels, but if you have hypothyroid symptoms, a mildly high TSH could be a sign of developing hypothyroidism. Free T3 (liothyronine) levels are not accurate in many labs, so a slightly low level may be meaningless. You should see an endocrinologist if you have symptoms. Read more...
