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.
Requesting the Total T4 Test in Alaska
Order online, choose a certified collection site in Alaska, and review results through a secure portal. No referral is required, and orders are processed confidentially. Because the region is uneven, coastal metros, inland towns, and rural counties with very different access to testing — worth planning around when you book.
Frequently asked questions
Do I need to fast for a total T4 test?
No, fasting is not needed. You can eat and drink normally before the blood draw.
What can affect my total T4 result?
Pregnancy, birth control pills, and some medications can raise or lower total T4. Always share your medication list with your provider.
Is total T4 the same as free T4?
No. Total T4 includes both bound and free hormone, while free T4 measures only the unbound, active portion. They are different tests.
How long until I get my results?
Results are typically available within 1 to 3 business days.
