Tiroxina
Tiroxina is the main hormone secreted in the blood stream by thyroid gland. It plays an important role in digestion, heart and muscle function, brain development and bone maintenance.

What is Tiroxina?
Tiroxina is the main hormone secreted in the blood stream by thyroid gland. It is an inactive form and most of these are actively converted into an active form called triiodothyronine by the organs such as the liver and kidneys. Thyroid hormonesplay an important role in regulating the body’s metabolic rate, heart and digestive function, muscle control, brain development and bone maintenance.

A Tiroxina test helps diagnose thyroid disorders. Thyroid is a small, butterfly-shaped gland located near the throat. Your thyroid produces hormone which regulates the way your body uses energy. It plays an important role in regulating your weight, body temperature, muscular strength, and even your mood. Tiroxina, also called T4, is a type of thyroid hormone. This test measures the level of T4 in your blood. Very high or very small T4 may indicate thyroid disease.
T4 Hormones come in Two Forms:• Free T4, which enters the body tissue where it is needed
• Bound T4, which is linked to the protein, prevents it from entering body tissues
• Bound T4, which is linked to the protein, prevents it from entering body tissues
A test which measures both free and bound T4 is called total T4 test. Other tests only make free T4 measures. Total T4 testing is considered to be more accurate than the total T4 test for the investigation of thyroid function.
Other Names:Free thyroxine, free T4, Total T4 concentration, Tiroxina screen, Free T4 concentration
what is it Used For?
A T4 test is used to evaluate thyroid function and diagnose thyroid disease.

How is Tiroxina Controlled?
The production and release of thyroid hormone, Tiroxina and triiodothyronine is controlled by a feedback loop system, which involves the hypothalamus in the brain and pituitary and thyroid glands. The hypothalamus passes through thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormones. This hormone stimulates the production of thyroid hormones, Tiroxina and triiodothyronine by thyroid gland. Read More
