Excess TSH is a substance found in the blood in most but not all people with an underactive thyroid gland (hypothyroidism). The test determines the level of TSH in the blood; this test gives the result as a number. The normal level for TSH is between 0.3 - 5.0 mIU/L. Interpretation of your test and medical advice is standard and included in the price of the test.
