A commonly ordered thyroid panel – this is a blood test that checks for two markers related to thyroid function, and calculates a third from those results.
- Free thyroxine index
- T3 uptake (THBR)
- Thyroxine (T4)
Typical turnaround time is within one day, although this may vary due to other tests ordered for the same blood draw, and expected variation of testing.
