RT Journal A1 Anagnostakis D, Mandyla H, Damianos D T1 CErebrospinal fluid protein concentration in full-term neonates JF Archives of Pediatrics & Adolescent Medicine JO Archives of Pediatrics & Adolescent Medicine YR 2001 FD May 1 VO 155 IS 5 SP 618 OP 619 DO 10.1001/archpedi.155.5.618 UL http://dx.doi.org/10.1001/archpedi.155.5.618 AB We agree strongly with the comment of Wong et al1 that cerebrospinal fluid (CSF) protein concentration is age dependent and that neonates have higher CSF protein values than older children. In an analogous study we examined CSF obtained by nontraumatic lumbar puncture from 63 full-term neonates (aged 0-4 weeks) who were evaluated for sepsis or meningitis.2 Of them, 38 with no sepsis or meningitis (bacterial or aseptic) and an uneventful clinical course were considered "healthy." The mean (range) CSF protein concentration in these healthy neonates was 0.49 g/L (0.25-0.82 g/L), similar to the concentration reported by Wong et al.
