About Total T4 Test | Thyroxine Blood Test - Thyroid Testing in Wheaton
Thyroxine is a hormone produced by the thyroid gland that regulates metabolism, energy, and growth.
Total T4 measures both bound and free thyroxine in the bloodstream. Most thyroxine circulates attached to transport proteins, while a smaller fraction remains unbound and biologically active.
Because total T4 reflects both bound and free hormone, results can be influenced by changes in binding proteins. Conditions such as pregnancy or liver disease may alter total T4 levels without necessarily indicating a thyroid disorder.
This test is typically ordered when a thyroid disorder is suspected or to monitor treatment for known thyroid conditions. It is often interpreted together with TSH and free T4 for a more complete assessment.
