New Guidelines for Thyroid Test
Over six years ago, the American National Academy of Clinical Biochemistry narrowed the window of normal for thyroid stimulating hormone (TSH) from 0.5-5 to 0.2-2.5mIU/L. Similar revisions by the American Association of Clinical Endocrinologists (AACE) meant that 13 million people previously considered to be normal, could now become officially diagnosed with underactive thyroid.

If you suspect low thyroid function, but have had "normal" blood tests, you and your doctor may want to take a second look. A TSH of greater than 2.5 is not normal.
