Total Thyroxine or T4 test 

The T4 test is used to evaluate thyroid function and diagnose thyroid disease.

Thyroxine (T4) is a thyroid hormone and the test measures how much is in your blood. Some thyroid diseases are tied to too little T4, and others are tied to too much.

Low values of T4 can be indicative of an underactive thyroid gland (called hypothyroidism) where the thyroid produces too little hormone.

Higher values of T4 occur when your thyroid gland is overactive (hyperthyroidism) and produces too much hormone, the body's metabolism speeds up.
