It's important to know that "total" T3 and T4 levels really don't tell much. Be sure that blood work is done to check "FREE" T3 and T4 levels. If the free levels of T3 and T4 aren't varying, it means that the TSH being produced by your body is keeping them level, but you don't say if any or all of these levels are within the lab normal range. It's also important to know that, in the last few years, what's considered a "normal" TSH level has changed. The upper end of the normal range used to be 6; now it's 3.

TSH is a sensitive marker for hypothyroidism and hyperthyroidism. Have a confirmatory test done. Any increase in TSH values indicates hypothyroidism and any decrease indicates hyperthyroidism. This is the opposite of T3 an T4 which are usually increased min hyperthyroidism and decreased in hypothyroidism.

YES. if the TSH falls or rises beyond the normal range i.e 0.5-4.7mU/mL in the presence of normal T3 and T4 u might be having subclinical hyerthyroidism/ sub clinical hypothyroidism resp. The second possibility is that the total T3 or T4 is normal but if u get a free T3/T4 levels done they might be abnormal too, in that case ur having overt thyroid dysfunction
