What is Total Thyroxine (TOTAL T4)?
The Total Thyroxine (T4) test measures the total amount of T4 hormone in your blood, which is produced by the thyroid gland. This hormone plays a vital role in regulating your body's metabolism, energy levels, and overall growth and development.
Why is this test important?
This test is crucial for evaluating thyroid gland function and diagnosing conditions like hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid). It helps doctors understand if your thyroid is producing too much or too little T4, guiding appropriate treatment.
