Neutrophil/Lymphocyte Ratio
The neutrophil-to-lymphocyte ratio is calculated from a standard CBC differential and reflects the balance between innate inflammatory and adaptive immune responses. Elevated ratios indicate systemic inflammation and stress and have been associated with worse outcomes in cardiovascular disease, cancer, infection, and critical illness. It is a simple, inexpensive marker of immune activation.
