Diurnal Hormone Profiling

Meaning

Diurnal Hormone Profiling is a specialized diagnostic practice that involves measuring the concentrations of specific hormones at multiple, timed intervals throughout a full 24-hour period. Unlike single-point blood draws, this comprehensive approach captures the natural, dynamic rhythm and fluctuation of key endocrine signals, such as cortisol, melatonin, and sex hormones. This detailed profiling is essential for accurately assessing the health of the hypothalamic-pituitary axes and identifying subtle phase shifts or amplitude disruptions that single-sample tests would fail to detect.
