About T3

What is T3?

Triiodothyronine (T3) is a hormone produced by the thyroid gland. T3 is the more powerful of the two main thyroid hormones (with T4 being the other), which regulate metabolism throughout the body.

The vast majority of T3 in the body is bound to other proteins, with the remaining unbound T3 called free T3.

Measuring T3 gives an indication of thyroid function. Abnormal levels of T3 can indicate thyroid problems such as hyperthyroidism or hypothyroidism.

Why take the test?

This test measures the level of T3 in the blood. It is typically used to diagnose thyroid problems.
