Some controversy: Most labs use the reference range of 0.5 - 4.70 or 5.0 miu/l for "normal". However, the american association of clinical endocrinologists (hormone specialists) recommend a narrower range: 0.3 - 3.0 your doc can advise you which reference range s/he follows.

TSH: It depends on lab normals. For most commercial labs it is less than 4.50 miu/ ml.
