It's funny you would post this because I was just reading how the thyroid hormone can be blocked at the tissue level. So, even if there is a "normal" amount in the blood, it isn't necessarily getting to the cells.

I also pulled up my May 2006 test results:

TSH 0.02 (0.38 to 5.5 is normal)
Free T4 = 9.7 (10.5 to 20 is normal)
(no Free T3)

I don't see why the sudden alarm in my doctor's attitude because of the difference from TSH being 0.02 or 0.01. (I was on the same dosage of desiccated with the results from this year and last.)

Digging even further back to 1996, when I was first diagnosed with just hypothryoidism, my TSH was 15.2. After two months and 25 mg. of Synthroid, my TSH was 8.0. Two months after that, and on 50 mg. of Synthroid, my TSH was 0.1.

Dosage was brought back down to 25 mg, and TSH was 5.6. Back up to 50 mg. (all two months apart) my TSH was 12.0.

Wild swinging, anyone? Wish someone then had known that was a symptom of Hashimoto's.

Thanks again for the thoughts... still preparing for battle...
