Thyroid Panel
The thyroid panel evaluates how your thyroid is working - TSH, free T4 and free T3. It's used when hypo- or hyperthyroidism is suspected, and for fatigue or weight changes.
Also known as: Thyroid Function Test · TFT · Thyroid Profile
Preparation: No special preparation is usually needed.
TSH is the most sensitive first-line marker; free T4 and T3 refine the picture. The values are interpreted together, not in isolation.

Frequently asked questions
Is TSH alone enough?
TSH is often the first screen, but if it's off, free T4 (and sometimes T3) is added to understand why. Read them together with your doctor.
Do time of day or food matter?
TSH varies through the day, and some supplements (biotin) distort the result. Follow your lab's instructions.
