Objective: Early diagnosis of sepsis is crucial to institute appropriate therapy and then to avert a possible negative outcome. We planned this study to evaluate the diagnostic value of presepsin, its sensitivity and specificity for diagnosing sepsis in critically ill patients, and its ability to prognosticate the outcome of sepsis. Methods: In this prospective observational study, adult patients admitted to the intensive care unit (ICU) at our institute were screened, and those with features suggestive of sepsis were recruited into the study. Procalcitonin (PCT) and presepsin were assessed on the day of admission and day 7 of the ICU stay, apart from routine investigations. Patients were followed for outcome in terms of mortality till 28 days. Results: The study comprised 82 patients who satisfied the inclusion criteria. Presepsin sensitivity for sepsis diagnosis was determined to be 78%, while that of PCT was determined to be 69%. This gave a combined sensitivity of presepsin and PCT of 93% when used in parallel for the diagnosis of sepsis. Conclusion: A combination of PCT and presepsin provides higher sensitivity and can be used to screen for sepsis in the ICU.
