What is the Origin of Endogenous Hormone Profiling?

This advanced diagnostic approach evolves from traditional clinical chemistry, leveraging highly sensitive analytical techniques like mass spectrometry to accurately quantify parent hormones and their downstream metabolites. The term emphasizes the focus on endogenous production, distinguishing it from the assessment of exogenous, or administered, hormones. Profiling is essential for understanding the nuances of individual hormonal metabolism and clearance rates.

What is the Mechanism of Endogenous Hormone Profiling?

The mechanism involves collecting biological samples, such as saliva, serum, or urine, at specific time points to map the secretory pattern of hormones like cortisol, sex steroids, and thyroid hormones. By analyzing the ratios of hormones and their metabolites, clinicians gain insight into enzymatic conversion pathways, receptor sensitivity, and clearance efficiency. This detailed profiling enables the identification of subtle dysfunctions not apparent with single-point blood draws.

Endogenous Hormone Profiling

Meaning

Endogenous Hormone Profiling is the precise measurement and temporal analysis of hormones naturally synthesized and secreted within the body, providing a comprehensive assessment of endocrine function. This clinical practice extends beyond simple static measurements, often utilizing dynamic testing or serial collections to capture the pulsatile and diurnal rhythms of key signaling molecules. The resulting profile informs targeted intervention strategies aimed at restoring physiological balance.
