Can you tell me what tests they did to rule out Hashimoto's? And do you have the actual results, with reference ranges?
Do you know if the T4 test that was done was a Free T4 or a Total T4? Those aren't the same tests and don't provide the same information. Typically, when we see "T4", we assume it's Total T4, which is considered obsolete and of little value; however, the result of yours, is one we, often, see for Free T4. Do you have the reference range for it?
