the total T3 ( TT3 or T3) and the T4 are stored hormones that do absolutely nothing to read or treat many hypothyroid patients.
"Free" T3 and T4 are the free flowing thyroid hormones that are useful in the body and can detect thyroid function.
Free T4 converts to active Free T3 - Free T3 is the most active form of thyroid hormone.
Can you explain more. You say they aren't good labs. Do you mean the lab didn't run the tests that should have been checked? What is free t3 and t4?
First I would interpret them being total T3 and Total T4 tests. These aren't good labs.
If I took a stab at them I would think you are storing your thyroid hormones and your Hashimoto antibodies are rearing up.
I think your doctor probably based alot on the TSH and that number is within the gold seal of being normal.
