Abstract:Aim: Early diagnosis of sepsis in the neonate is often difficult because symptoms and signs are usually non-specific. A study was conducted to evaluate C-reactive protein (CRP) as a screening tool for neonatal sepsis. Method: The prospective observational study was conducted at NICU, V. S. Hospital, Ahmedabad from January 2008 to June 2009. 75 neonates were included with the age group of first 28days (4week) of life (infant age) in study, all of which were suspected to have sepsis in clinical settings. All peripheral smear of neonate stained with Giemsa stain were reviewed .CRP performed by semi quantitative latex agglutination method. Positive cultures were the “gold standard” against which the performance of CRP , abnormal white blood cell counts (WBC) & absolute neutrophil counts (ANC) were compared. Results: Among 75 septic screens, 39 (52%) patients had positive cultures. The sensitivity and specificity of CRP 0.6 mg/dL was 92.30% and 85.71% respectively. Abnormal platelet count had the lowest specificity(45%) and sensitivity(23.07%) among them. Conclusion: CRP assay using semi quantitative latex agglutination method is a valuable adjunct in screening for neonatal sepsis, complementing clinical decision-making.
