FT4 (RIA) is a key test for evaluating thyroid function after TSH. It helps diagnose thyroid disorders and provides a more accurate picture of thyroid activity, especially in patients with abnormal Thyroid Binding Globulin (TBG) levels—such as pregnant individuals or those taking certain medications. FT4 is also used to screen newborns to ensure their thyroid gland is functioning normally.
No patient preparation necessary.
