What does Thyroid Profile Free (FT3, FT4 & TSH) measure?

Contains 3 tests

A Thyroid Profile Free (FT3, FT4 & TSH) measures the levels of three hormones in the blood, namely triiodothyronine hormone (T3) free, thyroxine hormone (T4) free, and thyroid-stimulating hormone (TSH). T3 and T4 are thyroid hormones that help regulate metabolism and energy levels in the body. On the other hand, TSH is produced by the pituitary gland and stimulates the thyroid gland to produce T3 and T4 hormones. T3 and T4 circulate in the blood in two forms: bound (attached to proteins) and free (does not attach to any protein). The serum levels of the thyroid hormones and TSH have an inverse relationship, i.e., low T4 (as observed in hypothyroidism) and high T4 (as seen in hyperthyroidism) levels are associated with high and low TSH levels, respectively.

Thyroxine - Free

A 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

A Triiodothyronine Free test measures the levels of free triiodothyronine (T3), a 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. Only a small portion of T3 is in the free form (not bound to proteins) and can be utilized by the body’s tissues, whereas more than 99% T3 is bound to proteins, such as albumin and thyroid-binding globulin (TBG), which prevent it from entering into the tissues. The body maintains a balance between bound and free T3 to ensure proper functioning.
