The ranges are different because he is quoting actual lab test (report) ranges. So they are different for the two individuals that he was discussing as case studies. The general range is the range used on his labs with Quest. He agreed with me that TSH is really meaningless when it comes to hypothyroidism dx and that he doesn't put much weight on it.

He agrees that the ranges are bad and again said that he doesn't use that as a dx tool. No more comment was made.

Thanks Steph! It's understandable now why he used the ranges in the book.
