I like the normal tsh test that seems to be the best inicator of where i am and need to be!
All TSH tests are now the same. The "sensitive" or "3rd Generation" are just the newest tests. The old versions haven't been offered in a while- like years.
Each lab has their own reference range, though.
I think your TSH fkuctuates and that may be a sign of "mild" thyroid trouble.
Request thyroid antibodies and always test close to the same time of day for accuracy and reprodicability.
Anything over a TSH of 2 and positive thyroid antibodies is likely abnornal. My endo says this is so.
Here is a great reference to explain it all:
Thyroid function test should be done early in the morning with no thyroxine replacement taken until after the blood test.
The TSH can fluctuate during the day but is at its highest first thing in the morning (around 8am).
If you take thyroxin medications before the blood tes, it will give a false reading.
