Neutrophils to Lymphocytes and Platelets Ratio, Procalcitonin, and Total Leucocytic Count as Indicators of Prognostic Outcome in Septic Patients in the Intensive Care Unit.

Sepsis affects more than 30 million people annually worldwide and is one of the significant causes of death in critical patients worldwide. Any infected person can potentially develop sepsis, and the incidence of sepsis is as high as 1-2% of all hospitalized patients. Many potential sepsis biomarkers have been proposed, procalcitonin (PCT) and C-reactive protein (CRP) being the most frequently studied. The ratio of neutrophils to lymphocytes and platelets (N/LP) is a low-cost measure that can be obtained through routine blood tests and is often used to reflect the body's inflammatory state.
