A Free T4 Levels Test measures the amount of unbound thyroxine (T4) in your blood. T4 is a thyroid hormone that helps control energy use, heart rate, and body temperature. Clinicians order it to check how well the thyroid is working, often alongside TSH.
What it measures
- Free T4 (free thyroxine) — The active, unbound portion of T4 that can enter tissues and affect metabolism.
- Total T4 — Sometimes measured with free T4 to show all T4 in the blood, bound and unbound.
- TSH (thyroid-stimulating hormone) — A pituitary hormone that tells the thyroid to make T4; often checked with free T4.
- Thyroid antibodies — Proteins that may attack thyroid tissue; added when autoimmune thyroid disease is suspected.
Who it is for
A clinician may order this test if you have symptoms such as fatigue, weight change, feeling cold or hot, or a known thyroid condition. It is also used to monitor thyroid treatment or during pregnancy when thyroid concerns exist.
Preparation
No fasting is usually required. Tell your clinician about any thyroid medicines, supplements, or biotin you take, because timing and some products can affect results.
Results and what they mean
Results are reported as a number with a reference range, which varies by lab. A clinician interprets your result with your symptoms, history, and other thyroid tests. This is general information, not medical advice; discuss your results with a qualified clinician.
