Order Total T4 Test | Thyroxine Blood Test - Thyroid TestingThe Total T4 test measures the amount of thyroxine, often called T4, that is circulating in the blood. Thyroxine is one of the two principal thyroid hormones, and its concentration offers a broad view of how the thyroid gland is performing. Because T4 is largely bound to carrier proteins in the bloodstream, the total T4 result reflects both bound and unbound hormone rather than the free fraction alone.
About Total T4 Test | Thyroxine Blood Test - Thyroid Testing in Riverton
Thyroxine is a hormone produced by the thyroid gland and released into the circulation, where it influences metabolism, growth, and energy use throughout the body.
Most thyroxine in the blood travels attached to transport proteins, with only a small portion remaining unbound and biologically active. A total T4 measurement captures the entire amount, which is why it is often interpreted alongside other thyroid markers such as TSH and free T4.
A total T4 result can fall above or below the usual reference range for a variety of reasons. Elevated values may occur with an overactive thyroid, while low values may accompany an underactive thyroid. Conditions that alter carrier proteins, including pregnancy and some liver or kidney disorders, can also shift total T4 without necessarily indicating a thyroid problem.
Clinicians use the Total T4 test as part of a broader thyroid evaluation. It is not a stand-alone diagnosis, and results are typically reviewed in the context of symptoms, medical history, and additional laboratory findings to determine whether thyroid function is normal, increased, or decreased.
