What is Free T4?
Free T4 (thyroxine) is an important hormone produced by the thyroid gland. It plays a crucial role in regulating your metabolism and energy utilization and affects virtually every organ in the body.
Why test for Free T4?
Testing Free T4 is useful for assessing thyroid function. It is particularly helpful for diagnosing hyperthyroidism or hypothyroidism, monitoring thyroid health in individuals using thyroid medication, and for evaluating overall metabolic health.
What does it indicate?
The Free T4 test measures the amount of free T4 hormone in the blood. It provides insight into how well the thyroid gland is functioning.
What does a high Free T4 level mean?
A high level of Free T4 may indicate hyperthyroidism, a condition in which the thyroid gland produces too much hormone. This can lead to symptoms such as weight loss, rapid heartbeat, nervousness, and excessive sweating.
What does a low Free T4 level mean?
A low level of Free T4 may indicate hypothyroidism, where the thyroid gland does not produce enough hormone. This can result in symptoms such as weight gain, fatigue, dry skin, and sensitivity to cold.
