A normal range for TSH in most laboratories is 0.4 milliunits per liter (mU/L) to 4.0 mU/L. If your TSH is higher than 4.0 mU/L on repeat tests , you probably have hypothyroidism. Your doctor may also order a T4 test.
What thyroid level is considered high?
Experts don’t agree on which TSH levels should be considered too high. Some suggest that TSH levels of over 2.5 milliunits per liter (mU/L) are abnormal, while others consider levels of TSH to be too high only after they have reached 4 to 5 mU/L .
What TSH level is considered severe hypothyroidism?
Normal and Abnormal TSH Ranges
TSH > 4.0/mU/L with a low T4 level indicates hypothyroidism. If your TSH is > 4.0 mU/L and your T4 level is normal, this may prompt your physician to test your serum anti-thyroid peroxidase (anti-TPO) antibodies.
Is thyroid level 2.9 good?
The normal range of TSH levels in adults is between 0.4 to 4.0 mIU/L (milli-international units per liter). Some research suggests that this range should actually be more like 0.45 to 2.5 mIU/L. The TSH range may also vary slightly based on the testing facility where your blood is being analyzed.
What is a high level for hypothyroidism?

TSH normal values are 0.5 to 5.0 mIU/L . Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in different range as guided by an endocrinologist. FT4 normal values are 0.7 to 1.9ng/dL.
Is a TSH level of 8 too high?
The standard reference range for the TSH level is anywhere between 0.30 and 5.0 uIU/mL. If your TSH level is higher than 5.0 uIU/mL , then the lab will flag you as “high,” and you may experience the symptoms listed above 5.0 uIU/mL. Values of the TSH level more than 10.0 uIU/mL need long-term thyroid supplements.

What is the best treatment for thyroid?
The most common treatment is levothyroxine (Levoxyl, Synthroid, Tirosint, Unithroid, Unithroid Direct), a man-made version of the thyroid hormone thyroxine (T4). It acts just like the hormone your thyroid gland normally makes. The right dose can make you feel a lot better.
