Understanding FT3 & FT4 (Free T3 & Free T4) in Kolkata


What is FT3 & FT4 (Free T3 & Free T4) in Kolkata?

The FT3 & FT4 (Free T3 & Free T4) test is a specialized test tailored to measure the amounts of free form of thyroxine (FT4) and thyroxine (FT4) present in the blood. This test helps evaluate how well your thyroid gland works and is available at an affordable price in Kolkata with Tata 1mg Labs. This test aids in diagnosing and monitoring thyroid disorders like goiter, Graves’ disease, or Hashimoto’s thyroiditis, which result from either an overactive (hyperthyroidism) or underactive (hypothyroidism) thyroid gland. Your doctor may suggest the FT3 & FT4 (Free T3 & Free T4) test when you have symptoms suggestive of a thyroid disorder, such as tiredness, mood swings, depression, muscle pain, nervousness, or anxiety.

This test is also recommended for pregnant women to ensure adequate levels of FT4 and FT4, both of which are crucial for the healthy development of babies and to prevent pregnancy complications. No special preparations are required for this test, and typically, there is no need to stop thyroid medication beforehand. However, inform your doctor about all medications you are taking, as some may impact thyroid function.

 

What does FT3 & FT4 (Free T3 & Free T4) measure?

Contains 2 tests

An FT3 & FT4 (Free T3 & Free T4) test measures the free form of triiodothyronine (FT3) and thyroxine (FT4) hormones made by the thyroid gland. These hormones exist in the blood in two forms: bound (attached to proteins) and free (not attached to proteins). Most of the T3 and T4 hormones circulating in the blood are bound to proteins and only a small part circulates freely and constitutes the physiologically active form. The body maintains a delicate balance of bound and free T3 as well as T4 to ensure proper functioning. Measuring free forms of thyroid hormones (FT3 and FT4) gives a better understanding of thyroid function than the bound forms as they are independent of changes in the concentration and the binding properties of the thyroid hormone binding proteins.

Thyroxine - Free

The Thyroxine - Free test measures the free form of thyroxine (T4) hormone made by the thyroid gland. T4 hormone exists in the blood in two forms: bound (attached to proteins) and free (not attached to proteins). Most of the T4 hormone circulating in the blood is bound to proteins and only a small part is free. A delicate balance of bound and free T4 should be maintained to ensure the proper functioning of the body.

Triiodothyronine Free

The Triiodothyronine Free test measures the levels of free triiodothyronine (T3), a hormone produced by the thyroid gland. T3 hormone plays a vital role in regulating the body's metabolism, energy levels, and growth & development. It exists in the blood in two forms: free T3 and bound T3. Only a small portion of T3 is free (not bound to proteins) and can be utilized by the body’s tissues. In contrast, more than 99% of T3 is bound to proteins, such as albumin and thyroid-binding globulin (TBG), preventing it from entering the tissues. The body balances bound and free T3 to ensure proper functioning.
