Tsh level is 3.2. doctor called with negative test result for hypothyroidism. why is no one following the new aace range of .3-3 that was made in 2003?

Because: This might be perfectly normal for you. Consult a real thyroidologist if you think you are hypothyroid. The mean TSH by newer criteria is about 2.5 and 2 sds might suggest that 3.2 is normal. If we were to repeat the TSH it might be even more in the normal range.

Nonsense: Cannot go by TSH alone, and 3.2 is highish. I suspect you may have a hypothyroid problem. Check free T3 and reverse t3. Ft3 should be in upper range and rt3 in lower range. If your ratio is off, you may need Armour Thyroid or t3, and synthroid (thyroxine) would be the wrong med for you.

Depends: You should discuss this with your current doctor. Remember that thyroid pill is a hormone. Do not use it unless it is necessary. You don't just take a hormone just to see how you feel on it. If you are really worried about this, ask your doctor for a free T4 and thyroid antibodies test. If antibodies are positive, then you have autoimmune thyroid disease and can start treatment with goal TSH <2.
