The Total T4 test measures the amount of thyroxine in the blood. Thyroxine is a hormone produced by the thyroid gland, and it plays a central role in regulating metabolism, energy use, and overall endocrine function. This test is commonly used alongside other thyroid tests to evaluate how well the thyroid is working.

About Total T4 Test | Thyroxine Blood Test - Thyroid Testing in Paramount

Thyroxine is one of the two primary hormones the thyroid gland produces.

The thyroid gland releases thyroxine, often called T4, into the bloodstream. Most of this hormone travels bound to carrier proteins, while a smaller portion circulates unbound. A Total T4 test measures both the bound and unbound thyroxine together, giving a broad view of the total amount present in the blood.

Because thyroxine influences how the body uses energy, abnormal levels can affect heart rate, body temperature, weight, and mood. A Total T4 result is typically interpreted alongside other thyroid markers, such as TSH and T3, to build a more complete picture of thyroid function.

Testing may be used when there are signs of an overactive or underactive thyroid. It can also help monitor thyroid status over time. Results are reported in relation to a reference range, and a physician interprets them in the context of symptoms, history, and other laboratory findings.
