What this test is

The T3 test is a blood test that checks the level of triiodothyronine, both free and bound forms. T3 is one of the main hormones produced by the thyroid gland and affects metabolism, heart rate, and body temperature. This test is often used along with other thyroid tests to get a fuller picture of thyroid function.

What it measures

  • Total T3 — reflects the total amount of triiodothyronine in the blood, including both bound and free forms
  • Free T3 — reflects the unbound, active portion of triiodothyronine that is available for the body to use

What the test involves

The test requires a standard blood draw from a vein in your arm. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order a T3 test if you have symptoms of an overactive or underactive thyroid, such as unexplained weight changes, fatigue, or heart palpitations. It can also be used to monitor treatment for thyroid conditions or to investigate an abnormal result from another thyroid test.

Preparation

Preparation instructions can vary depending on the laboratory and the specific method used. Always follow the instructions provided by the collection lab or your clinician.

How results are reported

Results are typically reported as a numeric value for total T3 or free T3, along with a reference range. Reference ranges differ between laboratories, so your result should be interpreted using the range provided by the testing lab.

Frequently asked questions

What is the difference between total T3 and free T3?

Do I need to fast before a T3 test?

Fasting is not usually required for a T3 test, but some laboratories may have specific instructions. It is best to check with the lab or your clinician before the test.

Can medications affect T3 test results?

Yes, certain medications, such as thyroid hormone replacements or some heart medications, can influence T3 levels. Always inform your clinician about any medications or supplements you are taking.

How long does it take to get T3 test results?

Results are typically available within a few business days, though this can vary by laboratory. Your clinician will discuss the results with you once they are ready.
