What does a TSH of 40 mean?

Patients who show too much response to TRH (TSH rises greater than 40) may be hypothyroid. This test is also used in cancer patients who are taking thyroid replacement to see if they are on sufficient medication. It is sometimes used to measure if the pituitary gland is functioning.

What is a good TSH level for a woman?

The normal range of TSH levels in non-pregnant adult women is 0.5 to 5.0 mIU/L. In women, during the menstruation cycle, pregnancy, or after menopause, TSH levels may fall slightly outside the normal range, because of fluctuating levels of estrogen.
