Free Triiodothyronine (Free T3)
The most active thyroid hormone, important in diagnosing an overactive thyroid.
T3 is formed from T4 in the tissues and has the strongest effect on energy use and heart rate.
Doctors order it mainly when an overactive thyroid is suspected, because it can rise before T4 does.
Preparation before the test
- No fasting needed; it can be done any time.
- Stop biotin (B7) supplements 48 hours before; it affects the result.
