T3

About Test

The T3 (Triiodothyronine) test measures the level of triiodothyronine, a thyroid hormone, in the blood. T3 is produced by the thyroid gland and plays a crucial role in regulating metabolism, energy levels, and overall bodily functions. It is one of the two main thyroid hormones, the other being thyroxine (T4).

The T3 test can be used to evaluate thyroid function and diagnose conditions related to thyroid hormone imbalances, such as hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid). Elevated T3 levels may indicate hyperthyroidism, thyroiditis, or thyroid hormone resistance. Low T3 levels can suggest hypothyroidism or conditions affecting the conversion of T4 to T3.

Monitoring T3 levels helps healthcare providers assess thyroid health, guide treatment for thyroid disorders, and ensure that thyroid hormone levels are maintained within the optimal range for overall well-being. Regular testing is important for adjusting treatment plans and managing conditions that affect thyroid function effectively.
