About Total T4 Test | Thyroxine Blood Test - Thyroid Testing in Modesto
Thyroxine is a hormone that the thyroid gland releases into the bloodstream, where it travels bound to carrier proteins.
The Total T4 test quantifies both the protein-bound and unbound portions of thyroxine in a blood sample. This distinguishes it from a free T4 test, which measures only the unbound fraction that is biologically active.
Physicians may order a Total T4 test to evaluate suspected hypothyroidism or hyperthyroidism, or to monitor thyroid function over time. Results are typically interpreted alongside other thyroid markers, such as TSH and T3, to form a complete picture.
The test involves a routine blood draw, and results are generally available within a few business days. Preparation instructions should be followed as provided by the laboratory performing the collection.
