Many health problems can trigger hyperthyroidism, such as toxic multinodular goiter or thyroiditis. Moreover, high protein levels in the blood can also cause high T4 levels. Conversely, low T4 levels indicate hypothyroidism, which is under-activity of the thyroid gland. What is being tested?The T4 test measures the quantity of the T4 hormone in the blood. This hormone is also called thyroxine hormone and it is synthesized by the thyroid gland in the body.Preparation needed?No, there is not any specific preparation necessary for the thyroxine blood test. Fasting required?No, but if you have been prescribed more tests along with this test, you might require to not drink or eat for some hours before the test.
