CHI3L1 and Sepsis: In this study, we sought to determine the diagnostic value of serum YKL-40 levels in term neonates with sepsis and to compare YKL-40 with other indices of inflammation, such as C-reactive protein (CRP), white blood cell count (WBC), absolute neutrophil count (ANC), and platelet count (PLT), currently used in clinical practice as sepsis biomarkers.
