Definition of T3 Test:
Triiodothyronine (T3) is a thyroid hormone. It plays an important role in the body’s control of metabolism (the many processes that control the rate of activity in cells and tissues). Triiodothyronine , also known as T₃, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. A laboratory test can be done to measure the amount of T3 in your blood.
Our Healthcare Lab Experts can help you understand the detailed parameters of the T3 Test for Thyroid.
T3 Test Normal Range:
A normal Total T3 level in adults ranges from 80-220 ng/dL. A T3 test is most often used to diagnose hyperthyroidism , a condition in which the body makes too much thyroid hormone.
Why is T3 Test done?
Most of the T3 in your body binds to protein. The T3 that doesn’t bind to protein is called free T3 and circulates unbound in your blood. The most common kind of T3 test, known as the T3 total test, measures both kinds of T3 in your blood. T3 tests are frequently ordered with T4 test and TSH (thyroid stimulating hormone) tests.
A T3 test may also be used to monitor treatment for thyroid disease. Free T3 assays are often unreliable and not routinely used to assess thyroid function. The free T3 test measures the active form of T3 that is not bound to protein, while the total T3 test measures bound T3 and free T3 combined.
Free T3 or total T3 blood tests may be ordered to evaluate thyroid function if a thyroid disorder is suspected. Triiodothyronine Test helps analyze your thyroid gland functioning and diagnose hyperthyroidism, in which your body makes too much thyroid hormone .
When your doctor suspects you have symptoms of hyperthyroidism, such as weight loss without trying, irregular or fast heartbeat, increased appetite, sweating, and more, they will prescribe the T3 Lab Test to examine your condition.
