Understanding Thyroxine - Total in Chennai
What is Thyroxine - Total in Chennai?
A Thyroxine - Total is a blood test that measures the level of total thyroxine (T4) hormone in the blood. This test helps assess overall thyroid function and detect possible thyroid disorders. It is also performed in combination with total T3 and TSH tests as part of a thyroid profile total test.
What does Thyroxine - Total measure?
A Thyroxine - Total measures both the bound and unbound/free form of thyroxine (T4) hormone in the blood. T4 exists in the blood in two forms: bound (attached to proteins) and free (not attached to proteins). Most of the T4 circulating in the blood is bound to proteins and only a small part is free. It is necessary to maintain a fine balance of these forms to ensure the proper functioning of the body.
