Sample Type

T3 sometimes referred to as triiodothyronine, is a crucial thyroid hormone that controls metabolism and makes sure your body can carry out critical processes effectively. While the majority of T3 in the circulation is protein-bound, part of it is unbound or free. In contrast to the total T3 test, which examines both bound and free T3, the free T3 test assesses the active form of T3 that is not bound to protein. If a thyroid condition is suspected, a free T3 or total T3 blood test may be requested to assess thyroid function. Moreover, they can be used to diagnose thyroid illness severity and type, monitor thyroid condition therapy, and examine pituitary gland issues.

Frequently asked questions

The disease hyperthyroidism, in which the body produces too much thyroid hormone, is most frequently diagnosed using a T3 test. TSH (thyroid stimulating hormone) and T4 tests are routinely ordered together with T3 testing. The therapy for thyroid illness may also be monitored by a T3 test.

For a T3 blood test, no extra preparations are required. If any medications need to be stopped before your test, your healthcare professional will let you know. T3 levels may increase or decrease depending on the drug.

A blood draw has a little amount of risk attached. In the location where the sample was taken, you could experience a little bruising.

The FT3 test results are out in 1 to 2 working days.
