Description

Use:

This test is used as a complementary study when evaualting thyroid function.

Free T4 may be indicated when binding globulin (TBG) problems are perceived, or when conventional test results seem inconsistent with clinical observations. It is normal in subjects with high thyroxine-binding globulin hormone binding who are euthyroid (ie, free thyroxine should be normal in nonthyroidal diseases). It should be normal in familial dysalbuminemic hyperthyroxinemia.

Diagnosing and monitoring treatment of hypo/hyperthyroidism.
