Circulating Hormone Thresholds

Meaning

Circulating Hormone Thresholds define the specific concentration range of a given hormone in the peripheral blood required to elicit a measurable and clinically significant biological effect in target tissues. Levels below this threshold may result in insufficient receptor binding and functional deficiency, while excessively high levels can lead to adverse saturation effects. Maintaining levels within an optimal therapeutic window is crucial for endocrine health. These thresholds vary based on tissue type and receptor sensitivity.
