1 Overview

This report examines the state-space trajectory of Absolute Neutrophils and Absolute Lymphocytes. Together, these markers define the Neutrophil to Lymphocyte Ratio (NLR).

  • Absolute Neutrophils: Absolute Neutrophils (ANC) measure the primary ‘first responders’ of the innate immune system. Chronic elevation suggests ongoing systemic stress or subclinical inflammation.
  • Absolute Lymphocytes: Absolute Lymphocytes represent the adaptive immune reserve. Optimal levels are necessary for effective viral surveillance and immune regulation.
  • Neutrophil to Lymphocyte Ratio (NLR): The NLR is a measure of the balance between innate and adaptive immunity. A trajectory moving toward the top-left (low lymphocytes, high neutrophils) indicates a shift toward systemic inflammation and physiological stress.
