What is the Origin of Tissue Receptivity Assessment?

This concept stems from molecular endocrinology and the clinical recognition that conditions like insulin resistance or thyroid hormone resistance represent a failure of tissue response, not necessarily a failure of hormone production. The term emphasizes the peripheral tissue's ability to receive and act upon the endocrine signal. This approach is essential for understanding why some patients are symptomatic despite having "normal" hormone levels.

What is the Mechanism of Tissue Receptivity Assessment?

While direct in-vivo measurement of receptor density is often impractical, assessment involves utilizing indirect biomarkers that reflect the downstream effects of hormone

Tissue Receptivity Assessment

Meaning

Tissue Receptivity Assessment is a clinical evaluation focused on determining the sensitivity of target cells and organs to circulating hormones, rather than merely measuring the hormone concentration itself. A high hormone level is functionally irrelevant if the target tissue lacks the appropriate receptor density or post-receptor signaling efficiency. This assessment provides crucial information about the functional bioavailability of a hormone and is paramount for tailoring personalized dosing strategies. It moves beyond standard lab work to address the cellular and molecular context of hormonal action.
