New Guidelines for Thyroid Test
Eight 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 under-active 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.
