FAQ
Frequently asked questions
What is the difference between free T3 and total T3?
Total T3 includes T3 bound to proteins and free T3 circulating in the blood. Free T3 is the active form that affects your body's tissues. Some tests measure both, while others focus on free T3.
Can medications affect T3 levels?
Yes, certain medications, including hormone replacement therapies and drugs that affect protein binding, can influence T3 levels. It is important to inform your doctor about all medications you are taking.
How does T3 relate to other thyroid hormones like T4?
T4 (thyroxine) is the primary hormone produced by the thyroid, and T3 is converted from T4 in the body. Both are essential for regulating metabolism, and doctors often order tests for both.
What does a low T3 level indicate?
Low T3 levels can suggest an underactive thyroid (hypothyroidism) or other conditions affecting hormone metabolism. However, results should always be interpreted by a healthcare professional in the context of your overall health.
