Diagnostic accuracy of serum procalcitonin (PCT) as an early biomarker of neonatal sepsis using blood culture as gold standard – Habib et al. (2021) [7]. Diagnostic accuracy of point-of-care (POC) testing of C-reactive protein, interleukin-6 (IL-6), and procalcitonin in neonates with clinically suspected sepsis: a prospective observational study – Goyal et al. (2024) [13]. C-reactive protein, procalcitonin, and white blood count to rule out neonatal early-onset sepsis within 36 hours: a secondary analysis of the Neonatal Procalcitonin Intervention Study – Stocker et al. (2021) [8]. This evidence concerns the gene CALCA and Sepsis.
