  1. All samples have been obtained by venous puncture, except blood gas analyses that have been performed on arterialized capillary blood samples obtained by warmed heel prick. All measurements have been performed with certified analytical micro-methods dedicated to the NICU and subjected to periodic quality controls. All results are normal for the neonatal reference ranges, expect for CSF proteins and leukocytes on DOL3; glycorrhachia was always similar to blood glucose measured at the same time.
  2. γ-GT, gamma-glutamyl transferase; ALT, alanine aminotransferase; AST, aspartate transaminase; BE, base excess; CRP, C-reactive protein; CSF, cerebro-spinal fluid; DOL, day of life; PCT, procalcitonin; RBC, red blood cells; WBC, white blood cells.
