Description

This thyroid panel measures T3, T4, and TSH to diagnose hypo‑ or hyperthyroidism. Thyroid dysfunction can affect weight, mood, heart rate and energy. Testing is advised for symptoms like fatigue, hair loss, palpitations or temperature intolerance and during pregnancy. Results help tailor levothyroxine or antithyroid therapy and determine follow‑up intervals. No fasting is required. Periodic monitoring ensures stable hormone levels and symptom control.
