What is Thyroxine T4?
Thyroxine (T4) is one of the two major hormones secreted by the thyroid gland. T4 hormone has four iodine molecules attached and is produced by the thyroid gland in much greater amounts than T3. T4 plays a role in the body’s vital functions, thus needs to be monitored. This test singly or in combination with T3 and TSH is used to identify thyroid disorders. FT4 is T4 which is not bound to the proteins and is related to thyroid metabolism. Low levels of FT4 indicate hypothyroidism and raised levels are associated with hyperthyroidism. Thyrocare offers a Free Thyroxine test at a very affordable price along with home collection facility.
