A total T4 test measures the total amount of thyroxine (T4), a thyroid hormone, in your blood. It is often ordered to help evaluate thyroid function when symptoms such as fatigue, weight changes, or irregular heartbeat are present.
What it measures
- Total T4 — The combined amount of T4 that is free and bound to proteins in the blood.
- Free T4 (indirect) — Sometimes calculated from total T4 and a protein measurement, but not directly measured in this test.
- Thyroxine-binding globulin (TBG) — A protein that binds T4; not directly measured, but its levels can affect total T4 results.
Who it is for
A healthcare provider typically orders a total T4 test when checking for an overactive or underactive thyroid, or to monitor thyroid treatment.
Preparation
No fasting is required. Tell your provider about any medications, especially thyroid drugs or birth control, as they can affect results.
Results and what they mean
Results are reported as a number with a reference range, usually in micrograms per deciliter (mcg/dL). A clinician interprets your result along with your symptoms, history, and other thyroid tests. This is general information, not medical advice.
