A free T3 test measures the amount of triiodothyronine (T3) in your blood that is not attached to proteins. It is ordered to help evaluate thyroid function, especially when total T3 or other thyroid tests give unclear results.
What it measures
- Free T3 — The active, unbound form of T3 hormone that can enter cells and affect metabolism.
- Total T3 (sometimes) — Measures both bound and free T3; may be included for comparison.
- Free T4 (sometimes) — Another thyroid hormone, often checked alongside free T3.
- TSH (sometimes) — A pituitary hormone that signals the thyroid; helps interpret T3 levels.
Who it is for
A healthcare provider typically orders this test when symptoms suggest an overactive thyroid (hyperthyroidism) or when other thyroid tests are inconclusive. It may also be used to monitor treatment for thyroid conditions.
Preparation
No fasting is usually required. Tell your provider about any medications or supplements you take, as some can affect T3 levels.
Results and what they mean
Results are reported as a number with a reference range, which varies by lab. A clinician interprets your free T3 level along with your symptoms and other tests. This is general information, not medical advice; discuss your results with a qualified healthcare professional.

How soon will I get my results?
