Reappraisal of C-reactive protein as a screening tool for neonatal sepsis

Abstract

Aims: To assess the usefulness of C-reactive protein (CRP) [either alone or in combination with a full blood examination (FBE) and microbiology of gastric aspirate] in predicting the diagnosis of neonatal sepsis compared with routinely available markers of infection. Methods: A prospective study of quantitative CRP, FBE, gastric aspirate and surface swab microscopy and culture in predicting neonatal sepsis in a level III perinatal referral hospital was performed. Results: Of 301 episodes evaluated over a 5-month period, there was a 5% rate of major (culture proven) sepsis (3% early onset, <72 hours) and 10% rate of modified sepsis. No single test alone was sufficiently reliable as an indicat..
