T3 is triiodothyronine, and is the active form of the hormone secreted by the thyroid. T4 (thyroxine) is another form of thyroid hormone which must be converted to T3 by your body via the deiodinase enzyme. Although T3 is active, your body produces much more T4.
The best way to monitor low thyroid function is by looking at TSH (thyroid stimulating hormone). TSH will be high if the thyroid is not producing enough T3/T4. For the majority of hypothyroid cases, only TSH needs to be monitored.
For hyperthyroidism and some hard to treat hypothyroid cases, the doctor will test T3 and T4.
