Order Total T4 Test | Thyroxine Blood Test - Thyroid TestingThe Total T4 test measures the amount of thyroxine circulating in the bloodstream.

Because thyroid hormones influence metabolism, energy use, and temperature regulation, a Total T4 measurement is often part of a broader evaluation of thyroid function.
About Total T4 Test | Thyroxine Blood Test - Thyroid Testing in Hobbs
Thyroxine and the thyroid gland
The thyroid gland sits in the neck and produces two main hormones: thyroxine (T4) and triiodothyronine (T3). T4 is the more abundant of the two, though much of it circulates bound to carrier proteins rather than acting freely. A Total T4 test measures both the bound and unbound portions together, which is why it is described as "total."
Total T4 results are interpreted alongside other thyroid markers, such as TSH and T3, rather than in isolation. A high Total T4 can point toward an overactive thyroid, while a low Total T4 can suggest an underactive thyroid. However, binding-protein levels, pregnancy, and certain medications can shift Total T4 without a true change in thyroid status, so context matters.
This test requires a blood draw, typically from a vein in the arm. Turnaround is usually one to three business days. Preparation instructions vary by laboratory, so following the lab's specific guidance is the most reliable approach before collection.
