Complete thyroid function assessment including TSH, T3, T4, and thyroid antibodies.
A thyroid panel evaluates how well your thyroid gland is functioning by measuring the hormones it produces and the pituitary signal that controls it. The thyroid is a butterfly-shaped gland in your neck that regulates metabolism, energy, body temperature, heart rate, and mood. A basic panel measures TSH (the brain's signal to the thyroid) and Free T4 (the main thyroid hormone). Comprehensive panels add Free T3 (the active hormone), reverse T3, and thyroid antibodies (TPOAb, TGAb) that can detect autoimmune conditions like Hashimoto's thyroiditis or Graves' disease. Thyroid dysfunction is extremely common — affecting roughly 1 in 8 women — and often goes undiagnosed because symptoms mimic stress, aging, or depression.
Key Details
Who Is This For?
Anyone experiencing unexplained fatigue, weight changes, hair loss, cold sensitivity, or mood disturbances. People with a family history of thyroid disease or autoimmune conditions. Women planning pregnancy, as thyroid function is critical for fetal brain development. Anyone who has had a 'normal' TSH result but still suspects thyroid dysfunction.
What's Included
Preparation Required
No fasting required for a standalone thyroid panel. If you take thyroid medication (levothyroxine/Synthroid), take your dose after the blood draw, not before — taking it beforehand can temporarily spike T4 levels and skew results. Morning testing is recommended for the most consistent TSH readings, as TSH follows a circadian rhythm and peaks overnight.
