The Thyroid Function Panel measures key hormones that regulate your metabolism, energy levels, and overall thyroid activity. It includes TSH, which signals your thyroid to produce hormones, along with Free T3 and Free T4, the active and storage forms of thyroid hormone. Together, these markers help determine whether your thyroid is underactive (hypothyroidism), overactive (hyperthyroidism), or functioning normally.
This panel is often recommended if you’re experiencing symptoms like fatigue, weight gain or loss, temperature sensitivity, or changes in mood and focus. It provides a foundational view of how well your thyroid is working and whether further testing or treatment may be needed to support healthy metabolic function.
