Good Morning:
Each lab has different ratios of what is considered normal for that lab.
It usually is on the lab report. Also if you are new to graves a
great reference book is “Your thyroid”-Wood, Cooper, Ridgway
ISBN 0-345-41006-8. This gives an overview of the tests and
lab values.
A great on line website explaining each of the tests can be found at:

Hope this helps.
