Order Total T4 Test | Thyroxine Blood Test - Thyroid TestingThe Total T4 test measures the total amount of thyroxine circulating in the blood, a hormone produced by the thyroid gland. Because thyroxine influences metabolism, heart rate, and body temperature, its concentration offers a useful view of thyroid function. This blood test is often used alongside other thyroid markers when evaluating suspected over- or underactivity of the gland.
About Total T4 Test | Thyroxine Blood Test - Thyroid Testing in Bountiful
Thyroxine and the thyroid
The thyroid gland, located in the neck, produces two principal hormones: thyroxine (T4) and triiodothyronine (T3). Although T3 is the more biologically active form, the thyroid secretes far more T4. Most T4 travels through the bloodstream bound to carrier proteins, while a smaller fraction remains free and available to tissues.
A Total T4 test quantifies both the bound and free portions of thyroxine together. That distinguishes it from a Free T4 test, which measures only the unbound fraction. Because binding proteins can shift for reasons unrelated to thyroid disease, total and free measurements sometimes tell different stories, and clinicians interpret them in context.
Results are typically considered alongside thyroid-stimulating hormone (TSH) and sometimes T3. A high total T4 may point toward hyperthyroidism, while a low value may suggest hypothyroidism, though pregnancy, certain medications, and other conditions can alter binding proteins and affect the total measurement. Turnaround for this test is generally one to three business days.
