What is the Origin of Personalized Biomarker Thresholds?

This concept is a direct evolution of clinical laboratory medicine, recognizing that the vast biological variability among humans renders standard population ranges insufficient for optimal health management. The personalization is rooted in the principles of genomics and systems biology. Clinicians use these tailored thresholds to guide therapeutic decisions and assess the true efficacy of an intervention for a specific patient.

What is the Mechanism of Personalized Biomarker Thresholds?

The establishment of these thresholds involves longitudinal monitoring of biomarkers across various physiological states, correlating those values with the patient's subjective well-being and objective functional outcomes. For example, an individual's optimal free testosterone level may be defined not by the population average, but by the level that consistently correlates with their highest energy, libido, and muscle mass. This mechanism ensures treatment targets are biologically meaningful and patient-centric.

Personalized Biomarker Thresholds

Meaning

Personalized Biomarker Thresholds are the clinically defined, optimal reference ranges for an individual’s specific physiological and hormonal markers, which are determined by integrating their unique genetic profile, health history, lifestyle data, and therapeutic goals. These thresholds move beyond the broad, population-based laboratory reference intervals to define a precise, individualized zone of peak function. Utilizing personalized thresholds is fundamental to precision medicine in endocrinology.
