Thyroid Profile + Free T3 T4 (FREE)








The Thyroid Profile + Free T3 T4 (FREE) package provides a comprehensive evaluation of thyroid function by combining a basic thyroid profile with advanced hormone assessment. The Thyroid Stimulating Hormone, along with total T3 and T4, forms the baseline thyroid profile, helping assess overall thyroid regulation and hormone production. TSH acts as the primary control signal from the pituitary gland, while total T3 and T4 reflect the circulating hormone pool (both bound and unbound). The add-on markers, Free T3 and Free T4, measure the biologically active (unbound) hormones available for use by the body. These provide deeper clinical insight, especially in cases where total values or TSH alone may be inconclusive. This combined approach ensures a more accurate and clinically meaningful assessment of thyroid health, helping differentiate between subclinical and overt thyroid disorders. Abnormal results may indicate conditions such as hypothyroidism or hyperthyroidism. This package is particularly useful for individuals experiencing symptoms like fatigue, weight changes, hair fall, or temperature sensitivity, or those with a family history of thyroid disorders. Regular monitoring supports early diagnosis, better clinical correlation, and effective management of thyroid conditions.











What does Thyroid Profile + Free T3 T4 (FREE) measure?
Contains 5 testsThe 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.

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.
