A thyroxine test is qualified as a blood test that assists in diagnosing thyroid conditions. The thyroid is a small, butterfly-shaped gland located at the base of your throat. It comprises hormones that regulate the process by which the body uses energy. As a result, these hormones not only affect your weight but also significantly impact your heart, body temperature, muscle strength, and mood. Also, it is seen that this disease affects children, too, affecting their growth drastically.
Also known as T4, thyroxine is a type of thyroid hormone. A T4 test calculates and examines the level of T4 in your blood. Regardless of whether the levels are too high or too low, fluctuating thyroid hormones in the body alert your body as a sign of thyroid disease. Also, there is a high chance that these thyroxine levels can lead to other chronic illnesses. Thus, to prevent your body from becoming the hub of all kinds of diseases, it is better to conduct an FT4 blood test in Noida and live a healthy and fit life.
Bound T4- It is considered thyroxine that attaches or binds to specific proteins and alerts them from entering your issues.
Free T4- It is known as the active form of thyroxine hormone that enters your tissues at the appropriate times when it's much needed.
Signs and symptoms of Low levels of thyroxine
Signs and symptoms of High- level of thyroxine
Hyperthyroidism- A condition of overactive thyroid where your gland doesn’t make enough thyroid hormone to fit the needs of your body.
Hypothyroidism- A condition of underactive thyroid where your gland makes an excess thyroid hormone than your body needs.
Pituitary gland disorders- Located at the base of your brain, a pituitary gland makes TSH that controls how much T4 your thyroid gland can make. Thus, if results from a TSH test aren’t found normal, it can indicate that the trouble is with your thyroid or pituitary gland.
