Background: In India, 25%–65% of neonatal deaths are due to sepsis. Since it produces nonspecific symptoms, it is difficult to diagnose and manage. The present study assessed the value of brain natriuretic peptide (BNP) and C-reactive protein (CRP) to predict sepsis along with blood culture. Materials and Methods: Samples were collected from 90 neonates with suspected sepsis, submitted for blood culture, CRP by latex agglutination kit, and BNP by ELISA. Results: Of the 90 cases, blood culture was positive in 25 (28%) cases, BNP in 45 (50%) cases, and CRP in 36 (40%) cases. BNP was positive among 25 (100%) blood culture-positive cases. CRP, BNP, and blood culture were positive in 16 (18%) cases. Conclusion: Although BNP is an equally good marker in predicting sepsis, it is not widely available. Hence, screening by serial CRP along with blood culture alone reinforces the diagnosis.
