You really *have* to find out exactly what was tested, exactly what the results were (the actual numbers) as well as the lab ranges for the testing lab. None of us will really have much of a clue until you get that information. For example, "testing of T1" doesn't even make any sense. That's not something that would be tested. TSH is usually the classic first test. And then possibly T4 and T3. Testing for thyroid antibodies is crucial for Hashimoto's diagnosis but I suspect that was not tested in your case.
