T4 is considered a reservoir or prohormone for T3, the biologically most active thyroid hormone. Measurement of total T4 gives a reliable indication of thyroid function in the absence of protein binding abnormalities (thyroid horomes not bound to a protein is called free T3 or T4). However, changes in binding proteins can occur which affect the level of total T4 but leave the level of unbound hormone unchanged.
