Product Details
The thyroid is a small, butterfly-shaped gland located in the neck. It produces T3 and T4 hormones that help regulate the body's metabolism, energy, and the function of vital organs. On the other hand, the TSH hormone is produced by the pituitary gland. This hormone acts as a messenger, telling the thyroid gland how much thyroid hormone (T3 & T4) it needs to make. An abnormal level of any of these three hormones can signal a thyroid problem, such as an underactive (hypothyroidism) or overactive (hyperthyroidism) gland.
The doctor may advise the Thyroid Profile Total (T3, T4 & TSH) test if there are symptoms suggestive of thyroid disorders, such as hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid).
Common symptoms of hypothyroidism include weight gain, fatigue, sensitivity to cold, constipation, dry skin, thinning hair, and irregular or heavier-than-usual menstrual periods. On the other hand, hyperthyroidism may cause unexplained weight loss, sensitivity to heat, irritability, mood swings, muscle weakness, hyperactivity, and difficulty sleeping.
Doctors also recommend the Thyroid Profile Total (T3, T4 & TSH) for women during pregnancy to check whether they have adequate thyroid hormone levels. These hormones are important for fetal brain development and pregnancy health.
The levels of thyroid hormones (T3 and T4) fluctuate due to changes in a protein called thyroxine-binding globulin (TBG). TBG helps carry thyroid hormones to the right parts of the body. The TSH level can vary depending on factors such as the time of day it is tested. That is why it's better to test TSH in the daytime for more accurate results.
No special preparations are needed for this profile. Usually, you do not need to discontinue taking thyroid medication before getting tested. However, inform your doctor about all medications you are taking, as some may affect the test results.
Lab test results may vary across laboratories. Interpreting test results requires expert guidance. Therefore, do not self-medicate, and talk to the doctor to understand the test results correctly.

The Thyroid Profile Total (T3, T4 & TSH) measures the circulating amounts of three key hormones:
- Total T3 (Total Triiodothyronine): T3 is the most active thyroid hormone and plays a major role in metabolism. The Thyroid Profile Total test measures both T3 bound to proteins and free T3 in the blood.
- Total T4 (Total Thyroxine): T4 is the primary hormone secreted by the thyroid gland. The Thyroid Profile Total test measures both protein-bound and free T4. It is a good indicator of overall thyroid hormone production.
- TSH (Thyroid Stimulating Hormone): This hormone, released by the pituitary gland, controls the production of T4 and T3 by the thyroid. It is the best screening test for determining whether the thyroid is functioning normally.
Triiodothyronine - Total (T3)
The Triiodothyronine - Total (T3) test 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
The TSH (Thyroid Stimulating Hormone) Ultrasensitive test measures the levels of TSH hormone in the blood. TSH is produced by the pituitary gland located at the base of 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 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). Vice versa happens when the levels of thyroid hormones increase.
Thyroxine - Total (T4)
The Thyroxine - Total (T4) test 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.
