According to the American Academy of Clinical Endocrinologists, the so-called "normal" range for TSH (Thyroid Stimulating Hormone) is actually wrong. Most labs consider a normal TSH value between 0.5-5.0. The AACE suggests labs consider a TSH between 1-2 normal and anything outside that range suspect. Thousands have undiagnosed thyroid problems. Go back to your doctor and request a full thyroid panel, including Free T-4
