Thyroxine
Explanation: Thyroxine (T4) is a hormone made by the thyroid gland, a small butterfly-shaped gland in the neck. It plays a critical role in regulating metabolism, heart rate, body temperature, and digestion, and it supports proper growth and development. After T4 is released, it gets converted into another hormone called triiodothyronine (T3), which is the active form that the body uses.
Test purpose: Testing T4 levels helps detect and manage thyroid-related conditions like hypothyroidism (underactive thyroid), hyperthyroidism (overactive thyroid), or thyroid nodules: Evaluate symptoms like fatigue, weight changes, rapid heartbeat, hair loss, or mood changes.
- Monitor thyroid treatment: For people taking thyroid medications, this test helps ensure the treatment is working properly.
