The greatest problems arise when defense mechanisms are overused in order to avoid dealing with problems. In psychoanalytic therapy, the goal may be to help the client uncover these unconscious defense mechanisms and find better, healthier ways of coping with anxiety and distress. Sigmund Freud's daughter, Anna Freud described ten different defense mechanisms used by the ego.
Speaking roughly, normal levels of thyroid-stimulating hormone (TSH) are in the range of 0.4 to 4.0 mIU/L. However, each laboratory and test manufacturer identifies its own normal TSH range. This is based on the test, the equipment being used, and the patients being tested.
Recommended TSH Levels May Not Be Right. Clinical chemists and doctors decided decades ago that healthy people with normal functioning thyroid glands have TSH levels within a range of 0.450 to 4.500 mIU/L (and some labs go as high as 5.000mIU/L). In clinical shorthand, the diagnostic range is rounded out to 0.4-4.0.
