A person with a normal thyroid hormone level is considered?

Normal thyroid hormone levels define an euthyroid state. When circulating thyroid hormones (T4 and T3) are within reference ranges and the pituitary response (TSH) is appropriate, the body isn’t signaling either overactivity or underactivity of the thyroid. Euthyroid means the thyroid is functioning normally. In contrast, hyperthyroidism means too much thyroid hormone production, leading to symptoms of increased metabolism; hypothyroidism means too little hormone, with slowed metabolism and fatigue; thyrotoxicosis or thyrotoxic states describe overall toxicity from excess thyroid hormone, not a normal level. So a person with a normal thyroid hormone level is euthyroid.
