Anyone having interest reading this, TSH is not the most important thyroid test. It's a close third to T4 and T3.
Unknowing Drs some times do this alone because they simply do not understand thyroid and/or they are trying to save money. The Free T3 and Free T4 have always been most important as these are the fuel your cells use.
TSH is only a signal, not "fuel", which unfortunately does not always correlate the way it should with T3 and T4 levels.
TSH has a standard range. Free T3 and Free T4 ranges will differ according to the test machine/brand used for testing- so you always need to include ranges when questioning these two.
Thyroid antibodies also have different ranges and/or limits according to test procedure/lab/machine used.
Sometimes when TSH and Frees contradict each other, treatment by trial and error are the only way to find out what's right for you.
If Ft3 and or FT4 are not over their ranges, and TSH is not super low, one is not hyper, but might be close. Its not an on/off light switch, its more like an adjustable dimmer.
Any T3 supplementation takes more than a week , but less than a month to get used to. Its an uncomfortable process.
