TSH Range
If the normal TSH range is 0.5-5.0, why is my doctor OK with 0.3 for the present time?
As discussed above, the most important consideration is symptoms. Are you having any symptoms? From your labs, I agree with Barb that your FT3 and FT4 levels are out of balance. FT4 is over the range and FT3 is low in the range. This is indicative of not converting T4 to T3 adequately. This can also be affected by having low iron/ferritin, and also low selenium. Good idea to test for those.
If you are still having hypo symptoms, then you will need to discuss with your doctor the need to adjust FT3 level upward and decrease your FT4. Is your doctor willing to treat you clinically by testing and adjusting FT3 and FT4 as necessary to relieve symptoms, without being constrained by resultant TSH levels? Also, is your doctor willing to prescribe meds other than T4 types? If the answer to either question is no, then you are going to have to either change his mind, or find a good thyroid doctor that will do so.

As gimel said, if you had a TT, that means you are on replacement hormones. What med are you on? At what dosage? Triiodothyronize is T3........ looks like you might not be converting FT4 to T3.

When taking thyroid medication the TSH is frequently suppressed below the range. This does not mean that you are hyper. You are hyper only if having hyper symptoms caused by excessive levels of FT3 andFT4. For example, I have had a TSH of about .05 for over 25 years without ever having hyper symptoms. In fact I had lingering hypo symptoms until learning about the importance of FT3 and getting my meds revised to include a source of T3. Now I feel best ever.
