Normal CSF values can vary by age. General reference ranges for pediatric patients include:
White blood cells (WBC): 0-5 cells/µL in infants, 0-10 cells/µL in neonates Red blood cells (RBC): 0-10 cells/µL Protein: 15-45 mg/dL in children, higher levels in neonates Glucose: 40-80 mg/dL, with CSF glucose typically about two-thirds of blood glucose levels
