Since 1994 after a partial thyroidectomy for Graves Disease I have been on 200mcg Levo. Over the last 2/3 years my GPs have asked me to reduce my dose as they told me I have been overmedicated. I am now taking 100mcg. I recently had a Blue Horizon test which included T3 which to my knowledge has not been tested before.
Here are my results:
TSH 0.039 ( reference range 0.270 - 4.2)
Free T4 26.98 ( 12-22)
Free T3 3.8 ( 3.1-6.8)
My TSH and Free T4 have risen since my last test ( though my dose of Levo was the same) but I do not understand the significance of the T3 result.
Can you help?
