What is the Origin of Biomarker Phase Sequencing?

The concept is a progression from traditional, single-sample biomarker analysis, borrowing rigor from longitudinal research studies and chronometric data analysis. It originated from the clinical need to understand the cyclical nature of human physiology, particularly the infradian rhythm of the menstrual cycle and the diurnal variations of hormones like cortisol. This sequencing approach enhances the predictive power of clinical diagnostics.

What is the Mechanism of Biomarker Phase Sequencing?

The process functions by establishing a baseline phase profile, followed by collecting sequential data points for biomarkers such as sex steroids, thyroid hormones, or inflammatory cytokines. Analyzing the rate of change and the phase-specific peak/trough levels allows for the identification of subtle regulatory dysfunctions. This sequential mapping is critical for calibrating personalized hormonal interventions to match the body's natural ebb and flow.

Biomarker Phase Sequencing

Meaning

A sophisticated analytical methodology involving the serial measurement and temporal correlation of multiple physiological and biochemical indicators across distinct, predefined biological or chronobiological phases. This process moves beyond static, single-point measurements to map dynamic shifts in the endocrine, metabolic, and inflammatory systems over time. It provides a nuanced clinical understanding of an individual’s health trajectory and response patterns.
