I had heard that over the years, there were no labs in existence for thyroid until the 70's...this proves it. Doctors back then went by symptoms and not numbers...

That is what my D.O. finally did for me after 10 years of numbers and no thyroid support.

The older I get, the more I dig, the more dirt I come up with. Labs can be a guideline but symptoms are what it is.
