Overview of Thyroid Profile Total
How Thyroid Profile Total helps you?
A Thyroid Profile Total (T3, T4 & TSH) offers a series of blood tests that measure the levels of thyroid hormones in the blood. Together, these tests help identify how well your thyroid gland works. It includes tests for thyroid-stimulating hormone (TSH), thyroxine hormone (T4)- total, and triiodothyronine hormone (T3)- total.
Precautions
1. You need not stop taking your thyroid medications on the day of the test unless otherwise advised by the doctor.
2. It is advisable to stop multivitamins or dietary supplements containing biotin (vitamin B7) for at least 2 days before the test.
Package Tests Included in Thyroid Profile Total (3 tests)
- Triiodothyronine Total
A Triiodothyronine Total measures triiodothyronine, also known as T3, hormone that is produced by the thyroid gland. T3 hormone plays an important 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. Free T3 is not bound to proteins in the blood and is the active form of T3. Whereas, bound T3 is bound to proteins, such as albumin and thyroid hormone binding globulin (THBG), which prevent it from entering the body tissues.
- TSH (Thyroid Stimulating Hormone) Ultrasensitive
A TSH (Thyroid Stimulating Hormone) Ultrasensitive test measures the levels of TSH hormone in the blood. TSH is produced by the pituitary gland located in the brain. Its function is to stimulate and regulate the functioning of the thyroid gland. It signals the thyroid gland to increase or decrease the production of thyroid hormones T3 and T4 (essential for regulating our body’s metabolism, temperature, heart rate, and growth) when their levels are low or high, respectively. Therefore, when the levels of T3 & T4 decrease, the pituitary gland is stimulated to release TSH. This high TSH level, in turn, stimulates the thyroid gland to release more thyroid hormones (T3 & T4); the vice-versa happens when the levels of thyroid hormones increase.
- Thyroxine - Total
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.
