The T4 test measures thyroxine, a hormone that plays a vital role in regulating metabolism, energy, and growth. It helps diagnose thyroid conditions like hypothyroidism or hyperthyroidism, especially when symptoms such as fatigue, weight changes, or neck swelling are present.
Often used with TSH and T3, this test is also helpful for monitoring thyroid treatment or screening those with a history of thyroid issues.
