A T3 test measures the amount of triiodothyronine, a thyroid hormone that helps regulate metabolism, in your blood. It is often ordered when a doctor suspects an overactive thyroid or wants to monitor a known thyroid condition.

What it measures

  • Total T3 — Measures all T3 in the blood, including T3 attached to proteins.
  • Free T3 — Measures only the unbound T3 that is active and available to body tissues.
  • Reverse T3 — An inactive form of T3; sometimes measured in special cases.

Who it is for

Doctors typically order a T3 test for people with symptoms of an overactive thyroid, such as weight loss or a fast heartbeat, or to follow up on abnormal thyroid test results.

Preparation

No fasting is usually required. Tell your doctor about any medicines or supplements you take, as some can affect T3 levels.

Results and what they mean

Results are reported as numbers with a reference range. Your clinician interprets them along with your symptoms and other thyroid tests. This is general information, not medical advice; only your clinician can diagnose or treat a thyroid condition.
