Clinical Significance
| High Levels of TSH TSH levels typically fall between 0.4 and 4.0 milliunits per liter (mU/L), according to the American Thyroid Association. Ranges between laboratories will vary with the upper limit generally being between 4 to 5. If your level is higher than this, chances are you have an underactive thyroid. In general, T3 and T4 levels increase in pregnancy and TSH levels decrease. |  |
Low Levels of TSH It’s also possible that the test reading comes back showing lower than normal levels of TSH and an overactive thyroid. This could be caused by: Graves’ disease (your body’s immune system attacks the thyroid)
- Too much iodine in your body
- Too much thyroid hormone medication
- Too much of a natural supplement that contains the thyroid hormone
