Thyroid Stimulating Hormone is secreted from the anterior pituitary gland and levels are based on a negative feedback loop to signal to the thyroid gland whether to release more Thyroxine or stop releasing. Conventionally along with free T4 the combination is considered the gold standard for assessing thyroid status. Levels are also affected by heavy metal burdens including Aluminium.
