Neutrophil-to-lymphocyte ratio in predicting mortality in sepsis and its correlation with sofa score and C-reactive protein values

A high value of NLR, SOFA score, and CRP on days 3 and 5 of admission in sepsis patients is associated with increased mortality. A serial increase in the value of NLR during the initial period of sepsis is a better marker for prediction of mortality, rather than a single point value, and the same is true for SOFA score and CRP values. NLR can be used as a simple, cheap, and easily available biomarker for sepsis during the initial period to predict severity and mortality.
