This thyroid panel includes TSH, T4, and T3, 3 common hormones used to measure thyroid function, and aid in the diagnosis of a thyroid disorder. This test will be able to identify both an overactive (hyperthyroidism) and underactive (hypothyroid).
TSH is Thyroid Stimulating Hormone. TSH is used as a screening test to determine if your thyroid gland is making appropriate amounts of thyroid hormones. TSH levels can help determine if someone is Hyperthyroid (making too much thyroid hormone) or Hypothyroid (making too little thyroid hormone). If the TSH is abnormal, a more comprehensive thyroid panel may be needed.
