Depends: Although they are usually pretty similar, each lab has its own set of reference values which should be reported along with the lab results. Contact the lab or doctor who ordered your test to find out for sure.

What is Normal: Every lab has a different standard for normal. And it depends on if you are looking at TSH (thyroid stimulating hormone), free T4 or total t3 (liothyronine). Find out the lab normals, and what is exactly being tested.
