Can anyone explain the ranges:
1. On what are these ranges based?
2. How can the ranges differ so widely in different areas. Surely the range is the range?
3. Ten years ago, top of the range in my area was 26. Today it is 14.7. How can this happen. Surely the repurcussions are enormous.
4. My body is not going to change because Joe Bloggs has decided to bring the range down ten points. My cells are not going to suddenly decide they need a whole lot less thyroxine because the range has been reduced overnight. How does the medical profession work with this?
