<p>Used to evaluate thyroid function and binding protein status. In hyperthyroidism if TSH levels are low but the FT4 level is normal, a T3 measurement should be performed, since the serum T3 concentration is often elevated earlier in the course of hyperthyroidism and to a greater degree than the T4 concentration.</p>
