What is the Free Triiodothyronine (FT3)?

Free T3 measures the unbound, biologically active portion of triiodothyronine (T3), one of the main thyroid hormones. Unlike total T3, it isn’t affected by changes in binding proteins, making it a more precise marker in certain situations.

Why is the Free Triiodothyronine (FT3) done?

Ordered alongside TSH and Free T4 to more precisely evaluate thyroid function, especially when total T3/T4 results are affected by conditions like pregnancy or liver disease that change binding protein levels.

It can help your doctor assess

Hyperthyroidism (when elevated) and, in specific patterns, certain forms of hypothyroidism.

Who may need this test?

This test may be considered for:

People being evaluated for hyperthyroidism, or when total thyroid hormone results are difficult to interpret due to altered binding proteins (e.g. pregnancy, liver disease, certain medicines).

Whether this test is right for you depends on your symptoms, medical history and the reason for testing - your doctor can advise.

What does this test measure?

The free (unbound, active) fraction of T3 hormone in the blood.

Free T3

Thyroid Hormone

The active, unbound form of T3 - more reliable than total T3 when binding-protein levels are altered by pregnancy, liver disease or certain medicines.

Understanding your Free Triiodothyronine (FT3) results

How to read your result

Your report should be read using the reference interval, unit and method shown by the performing laboratory. A result outside a reference interval does not automatically establish a diagnosis, and a result inside the interval does not rule out every health problem. Clinical interpretation depends on symptoms, history and other findings.

MarkerResultWhat it may be associated with
Free T3High, TSH LowSupports a diagnosis of hyperthyroidism.

If a result is outside the range

If the Free Triiodothyronine (FT3) is reported as high, low, positive, negative or otherwise outside the laboratory's stated interval, the meaning depends on the specific test and the reason it was ordered. Your clinician may consider repeat testing, related investigations or other clinical information before deciding what the result means.

Limitations of this test

Free T3 alone doesn’t give the full thyroid picture - it’s combined with TSH and Free T4 for accurate interpretation.

An abnormal result does not by itself mean you have a particular disease. Your doctor interprets results together with your symptoms, history and other tests.
