A comprehensive thyroid panel measures multiple thyroid hormones and related markers to evaluate overall thyroid function. This panel is essential for diagnosing thyroid disorders such as hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). The test measures thyroxine (T4), T3 uptake, and calculates the free thyroxine index (FTI) to provide a complete picture of thyroid health. Thyroid disorders can cause symptoms like fatigue, weight changes, mood disturbances, and heart problems. This panel is commonly ordered when patients experience unexplained symptoms, have a family history of thyroid disease, or need monitoring of existing thyroid conditions. Regular thyroid testing is important for maintaining overall health and energy levels.
